The United States Industrial Electric Motor Systems Market Opportunities Assessment: Key Results
E-Print Network (OSTI)
This paper summarizes the findings of the U. S. Industrial Electric Motor Systems Market Opportunities Assessment. The Market Assessment was sponsored by the U. S. Department of Energy. The project's principal objectives were to create a detailed portrait of the inventory of motor systems currently in use in US industrial facilities, estimate motor system energy use and potential for energy savings. The research and analysis to support these objectives consisted primarily of on-site motor system inventories of a probability sample of 254 manufacturing facilities nationwide. In addition to characterizing the motor systems in use, the research effort also gathered detailed information on motor system management and purchasing practices. This paper presents key findings from the Market Assessment in regard to patterns of motor energy use, saturation of energy efficiency measures such as efficient motors and adjustable speed drives, and motor system purchase and maintenance practices.

Ultra-Efficient and Power Dense Electric Motors for U. S. Industry
SciTech Connect
The primary purpose of this project was to combine the ease-of-installation and ease-of-use attributes of industrial induction motors with the low-loss and small size and weight advantages of PM motors to create an ultra-efficient, high power density industrial motor that can be started across-the-line or operated from a standard, Volts/Hertz drive without the need for a rotor position feedback device. PM motor products that are currently available are largely variable speed motors that require a special adjustable speed drive with rotor position feedback. The reduced size and weight helps to offset the magnet cost in order make these motors commercially viable. The scope of this project covers horsepower ratings from 20 ? 500. Prototypes were built and tested at ratings ranging from 30 to 250 HP. Since fans, pumps and compressors make up a large portion of industrial motor applications, the motor characteristics are tailored to those applications. Also, since there is extensive use of adjustable frequency inverters in these applications, there is the opportunity to design for an optimal pole number and operate at other than 60 Hz frequency when inverters are utilized. Designs with four and eight pole configurations were prototyped as part of this work. Four pole motors are the most commonly used configuration in induction motors today. The results of the prototype design, fabrication, and testing were quite successful. The 50 HP rating met all of the design goals including efficiency and power density. Tested values of motor losses at 50 HP were 30% lower than energy efficient induction motors and the motor weight is 35% lower than the energy efficient induction motor of the same rating. Further, when tested at the 30 HP rating that is normally built in this 286T frame size, the efficiency far exceeds the project design goals with 30 HP efficiency levels indicating a 55% reduction in loss compared to energy efficient motors with a motor weight that is a few percentage points lower than the energy efficient motor. This 30 HP rating full load efficiency corresponds to a 46% reduction in loss compared to a 30 HP NEMA Premium? efficient motor. The cost goals were to provide a two year or shorter efficiency-based payback of a price premium associated with the magnet cost in these motors. That goal is based on 24/7 operation with a cost of electricity of 10 cents per kW-hr. Similarly, the 250 HP prototype efficiency testing was quite successful. In this case, the efficiency was maximized with a slightly less aggressive reduction in active material. The measured full load efficiency of 97.6% represents in excess of a 50% loss reduction compared to the equivalent NEMA Premium Efficiency induction motor. The active material weight reduction was a respectable 14.5% figure. This larger rating demonstrated both the scalability of this technology and also the ability to flexibly trade off power density and efficiency. In terms of starting performance, the 30 ? 50 HP prototypes were very extensively tested. The demonstrated capability included the ability to successfully start a load with an inertia of 25 times the motor?s own inertia while accelerating against a load torque following a fan profile at the motor?s full nameplate power rating. This capability will provide very wide applicability of this motor technology. The 250 HP prototype was also tested for starting characteristics, though without a coupled inertia and load torque. As a result it was not definitively proven that the same 25 times the motor?s own inertia could be started and synchronized successfully at 250 HP. Finite element modeling implies that this load could be successfully started, but it has not yet been confirmed by a test.

Parametric electric motor study
DOE Green Energy (OSTI)
Technology for the axial gap motor was developed by DOE with an investment of approximately $15 million. This development effort is for motor technologies of high power density and high efficiency. Such motors that are also small and light-weight are not available on the commercial market because high-power motors have typically been used in large industrial applications where small size and light weight are not requirements. AC Delco has been developing motors since 1918 and is interested in leveraging its research and development dollars to produce an array of motor systems for vehicles and to develop a future line of propulsion products. The DOE focus of the study was applied to machining applications. The most attractive feature of this motor is the axial air gap, which may make possible the removal of the motor`s stationary component from a total enclosure of the remainder of the machine if the power characteristics are adequate. The objectives of this project were to evaluate alternative electric drive systems for machine tools and automotive electric drive systems and to select a best machine type for each of those applications. A major challenge of this project was to produce a small, light-weight, highly efficient motor at a cost-effective price. The project developed machine and machine drive systems and design criteria for the range of applications. The final results included the creation of a baseline for developing electric vehicle powertrain system designs, conventional vehicle engine support system designs, and advanced machine tool configurations. In addition, an axial gap permanent magnet motor was built and tested, and gave, said one engineer involved, a sterling performance. This effort will commercialize advanced motor technology and extend knowledge and design capability in the most efficient electric machine design known today.

Efficient electric motor systems for industry. Report on roundtable discussions of market problems and ways to overcome them
Improving the efficiency of electric motor systems is one of the best energy-saving opportunities for the United States. The Department of Energy (DOE) Office of Industrial Technologies estimates that by the year 2010 in the industrial sector, the opportunities for savings from improved efficiency in electric motor systems could be roughly as follows: 240 billion kilowatthours per year. $13 billion per year from US industry`s energy bill. Up to 50,000 megawatts in new powerplant capacity avoided. Up to 44 million metric tons of carbon-equivalent emissions mitigated per year, corresponding to 3 percent of present US emissions. Recognizing the benefits of this significant opportunity for energy savings, DOE has targeted improvements in the efficiency of electric motor systems as a key initiative in the effort to promote flexibility and efficiency in the way electricity is produced and used. Efficient electric motor systems will help the United States reach its national goals for energy savings and greenhouse gas emission reductions.

Development of Ulta-Efficient Electric Motors
Electric motors utilize a large amount of electrical energy in utility and industrial applications. Electric motors constructed with high temperature superconducting (HTS) materials have the potential to dramatically reduce electric motor size and losses. HTS motors are best suited for large motor applications at ratings above 1000 horsepower (hp), where the energy savings from the efficiency improvement can overcome the additional power required to keep the superconductors on the rotor cooled. Large HTS based motors are expected to be half the volume and have half the losses of conventional induction motors of the same rating. For a 5000 hp industrial motor, this energy savings can result in $50,000 in operating cost savings over the course of a single year of operation. Since large horsepower motors utilize (or convert) about 30% of the electrical power generated in the United States and about 70% of large motors are candidates for replacement by HTS motors, the annual energy savings potential through the utilization of HTS motors can be up to $1 Billion in the United States alone. Research in the application of HTS materials to electric motors has lead to a number of HTS motor prototypes yet no industrial HTS motor product has yet been introduced. These motor demonstrations have been synchronous motors with HTS field windings, on the rotor. Figure 1-1 shows a solid model rendering of this type of motor. The rotor winding is made with HTS coils that are held at cryogenic temperature by introducing cooling fluid from the cryocooler to the rotor through a transfer coupling. The stator winding is made of copper wire. The HTS winding is thermally isolated from the warm armature and motor shafts by a vacuum insulation space and through the use of composite torque tubes. The stator in Figure 1-1 is an air core stator in that the stator teeth and a small part of the yoke is made up of nonmagnetic material so the magnetic fields distribute themselves as if in air. Between the HTS field winding and the physical air gap is a series of concentric cylinders that act as vacuum insulation space walls as well as conducting paths for induced currents to flow in order to shield the HTS winding and the rotor cold space from time dependent fields. These time dependent fields may be caused by rotor hunting, during a change in motor load, or by non-fundamental component voltages and currents applied by the inverter. These motors are variable speed controlled by the inverter. Common large motor utility and industrial applications are pump and fan drives that are best suited by a variable speed motor. Inverter control of the HTS motor eliminates the need to design the rotor for line starting, which would dump a large amount of heat into the rotor that would then heavily tax the cryogenic cooling system. The field winding is fed by a brushless exciter that provides DC current to the HTS rotor winding. The stator winding is air or water cooled. Technical and commercial hurdles to industrial HTS motor product introduction and customer acceptance include (1) the high cost of HTS wire and the cryogenic cooling system components, (2) customer concerns about reliability of HTS motors, and (3) the ability to attain the loss reduction potential of large HTS motors. Reliance Electric has demonstrated a number of HTS based electric motors up to a 1000 hp, variable speed synchronous motor with an HTS field winding in the year 2000. In 2001 this motor was tested to 1600 hp with a sinusoidal (constant frequency) supply. Figure 1-2 shows the HTS motor on the dynamometer test stand in the Reliance Electric test lab. The extensive test program of the 1000 hp motor successfully demonstrated the technical feasibility of large HTS motors and the basic technologies involved, however the test results did indicate the need for design refinements. In addition, test results served to identify other more fundamental critical technology issues, and revealed the need to continue research efforts in order to improve future HTS motor first cost, reliability, and performa

Aging assessment of large electric motors in nuclear power plants
Large electric motors serve as the prime movers to drive high capacity pumps, fans, compressors, and generators in a variety of nuclear plant systems. This study examined the stressors that cause degradation and aging in large electric motors operating in various plant locations and environments. The operating history of these machines in nuclear plant service was studied by review and analysis of failure reports in the NPRDS and LER databases. This was supplemented by a review of motor designs, and their nuclear and balance of plant applications, in order to characterize the failure mechanisms that cause degradation, aging, and failure in large electric motors. A generic failure modes and effects analysis for large squirrel cage induction motors was performed to identify the degradation and aging mechanisms affecting various components of these large motors, the failure modes that result, and their effects upon the function of the motor. The effects of large motor failures upon the systems in which they are operating, and on the plant as a whole, were analyzed from failure reports in the databases. The effectiveness of the industry`s large motor maintenance programs was assessed based upon the failure reports in the databases and reviews of plant maintenance procedures and programs.

Electric motor systems in developing countries: Opportunities for efficiency improvement
This report presents an overview of the current status and efficiency improvement potential of industrial motor systems in developing countries. Better management of electric motor systems is of particular relevance in developing countries, where improved efficiency can lead to increased productivity and slower growth in electricity demand. Motor systems currently consume some 65--80% of the industrial electricity in developing countries. Drawing on studies from Thailand, India, Brazil, China, Pakistan, and Costa Rica, we describe potential efficiency gains in various parts of the motor system, from the electricity delivery system through the motor to the point where useful work is performed. We report evidence of a significant electricity conservation potential. Most of the efficiency improvement methods we examine are very cost-effective from a societal viewpoint, but are generally not implemented due to various barriers that deter their adoption. Drawing on experiences in North America, we discuss a range of policies to overcome these barriers, including education, training, minimum efficiency standards, motor efficiency testing protocols, technical assistance programs, and financial incentives.

Economic Realities and Energy Efficient Polyphase Integral Horsepower Electric Motors
Energy efficient polyphase integral horsepower electric motors are currently being vigorously promoted as a profitable method of conserving energy in many industrial and commercial applications. While the goal to be attained is indeed laudable, and must be tenaciously pursued, the economic realities of investment payback on increased efficiency versus cost of change out, power factor, etc. must have a meaningful review before decision making. Actual savings on a discount cash flow basis must be documented. and validity of the claims for the energy efficient motor must be verified. This paper develops the procedures used by the chemical manufacturing divisions of the Union Carbide Corporation in developing a long range plan for evolution from a motor population of standard efficiency units to one of higher efficiency and increased reliability. It notes statistics publicized by the U.S. Department of Energy, Union Carbide's overall electric equipment efficiency review, their own efficiency testing of sample small electric motors, and a pilot program to determine the number of lightly loaded motors in plant location. It further depicts an economic appraisal on the payback of replacing a standard efficiency motor with a higher efficiency unit and an action plan for purchasing energy efficient motors while simultaneously securing optimization of other parameters.

Distributed monitoring system for electric-motor-driven compressors
Personnel in the Instrumentation and Controls Division at the Oak Ridge National Laboratory, in association with the United States Enrichment corporation (USEC), the Navy, and various Department of Energy sponsors, have been involved in the development and application of motor-current signature analysis (CSA) for several years. In that time CSA has proven to not only be useful for manually applied periodic monitoring of electrically driven equipment but it has also been demonstrated to be well suited for dedicated monitoring systems in industrial settings. Recent work has resulted in the development and installation of a system that can monitor up to 640 motor and compressor stages for various aerodynamic conditions in the gas compressors and electrical problems in the drive motors. This report describes a demonstration of that technology installed on 80 stages at each of the two USEC uranium enrichment plants.

Demirel, Melik C.
This report contains the final project summary and deliverables required by the award for the development of an In-line Electric Motor Driven Compressor (IEMDC). Extensive work was undertaken during the course of the project to develop the motor and the compressor section of the IEMDC unit. Multiple design iterations were performed to design an electric motor for operation in a natural gas environment and to successfully integrate the motor with a compressor. During the project execution, many challenges were successfully overcome in order to achieve the project goals and to maintain the system design integrity. Some of the challenges included limiting the magnitude of the compressor aerodynamic loading for appropriate sizing of the magnetic bearings, achieving a compact motor rotor size to meet the rotor dynamic requirements of API standards, devising a motor cooling scheme using high pressure natural gas, minimizing the impact of cooling on system efficiency, and balancing the system thrust loads for the magnetic thrust bearing. Design methods that were used on the project included validated state-of-the-art techniques such as finite element analysis and computational fluid dynamics along with the combined expertise of both Curtiss-Wright Electro-Mechanical Corporation and Dresser-Rand Company. One of the most significant areas of work undertaken on the project was the development of the unit configuration for the system. Determining the configuration of the unit was a significant step in achieving integration of the electric motor into a totally enclosed compression system. Product review of the IEMDC unit configuration was performed during the course of the development process; this led to an alternate design configuration. The alternate configuration is a modular design with the electric motor and compressor section each being primarily contained in its own pressure containing case. This new concept resolved the previous conflict between the aerodynamic flow passage requirements and electric motor requirements for support and utilities by bounding the flowpath within the compressor section. However most importantly, the benefits delivered by the new design remained the same as those proposed by the goals of the project. In addition, this alternate configuration resulted in the achievement of a few additional advantages over the original concept such as easier maintenance, operation, and installation. Interaction and feedback solicited from target clients regarding the unit configuration supports the fact that the design addresses industry issues regarding accessibility, maintainability, preferred operating practice, and increased reliability.

Marketing Reordering of the Electric Utility Industry
ELCON is a group of large industrial consumers of electricity with facilities in most of the 50 states and many foreign countries. Our members produce a wide range of products including steel, aluminum, chemicals, industrial gases, glass, motor vehicles, textiles and food. ELCON members consume approximately ten percent of all electricity sold to industrial customers and nearly five percent of all electricity consumed in the United States. We require an adequate and reliable supply of electricity at reasonable prices, so as you can imagine, we have a continuing interest in all aspects of the production, pricing, and delivery of electricity. ELCON member companies believe strongly that the electric utility industry is undergoing a market reordering that is being shaped by technological, institutional and legal forces. We see technical developments that now make small-scale generation economically attractive, if not downright desirable. Key regulatory and consumer institutions are taking fresh, new looks at issues such as wheeling and access to the grid that used to be considered sacred and untouchable. Some states are passing laws and implementing regulations that will require new thinking and new operating procedures on the part of utilities and consumers. I see these developments as logical reactions to changes in market forces. Change will take place. The relevant questions are: How will regulators and policy makers be influenced by market forces in the future? And: Will utilities, consumers and regulators attempt to benefit from market pressures or, alternatively, try to oppose what I believe is inevitable evolution to a more market-oriented electric industry?

The Wanlass Polyphase Rotating Magnetic Device in Electric Motor and Induction Generator Applications
The electric motor in its present technological configuration has remained virtually unchanged since its original conception nearly 100 years ago. It would be logical to assume that a device, which has undergone such insignificant evolution, would have small impact with reference to industry. This paper will provide an introduction to the Wanlass technology and its application to induction motors and generators. This will be accomplished through analysis of motor and generator tests.

Minimum Efficiency Standards for Electric Motors | Department of Energy
Minimum Efficiency Standards for Electric Motors Minimum Efficiency Standards for Electric Motors Minimum Efficiency Standards for Electric Motors October 7, 2013 - 11:28am Addthis Section 313 of the Energy Independence and Security Act (EISA) of 2007 raised Federal minimum efficiency standards for general-purpose, single-speed, polyphase induction motors of 1 to 500 horsepower (hp). This new standard took effect in December 2010. The new minimum efficiency levels match FEMP's performance requirement for these motors. As a result of this increase in mandatory minimum standards and combined with the lack of significant availability of motors exceeding these standards, FEMP is suspending the purchasing specification for electric motors. Federal buyers may select for purchase any motor that meets design requirements.

IEMDC - In-Line Electric Motor Driven Compressor
This report covers the fifth quarter (01/01/04 to 03/31/04) of the In-Line Electric Motor Driven Compressor (IEMDC) project. Design efforts on the IEMDC continued with compressor efforts focused on performing aerodynamic analyses. These analyses were conducted using computational fluid dynamics. Compressor efforts also entailed developing mechanical designs of components through the use of solid models and working on project deliverables. Electric motor efforts focused on the design of the magnetic bearing system, motor pressure housing, and the motor-compressor interface. The mechanical evaluation of the main interface from both the perspective of the compressor manufacturer and electric motor manufacturer indicates that an acceptable design has been achieved. All mechanical and aerodynamic design efforts have resulted in considerable progress being made towards the completion of the compressor and electric motor design and towards the successful completion of the IEMDC unit.

Summary of electric vehicle dc motor-controller tests
Available performance data for production motors are usually of marginal value to the electric vehicle designer. To provide at least a partial remedy to this situation, tests of typical dc propulsion motors and controllers were conducted as part of the DOE Electric Vehicle Program. The objectives of this program were to evaluate the differences in the performance of dc motors when operating with chopper-type controllers and when operating on direct current; and to gain an understanding of the interactions between the motor and the controller which cause these differences. Toward this end, motor-controller tests performed by the NASA Lewis Research Center provided some of the first published data that quantified motor efficiency variations for both ripple-free (straight dc) and chopper modes of operation. Test and analysis work at the University of Pittsburgh explored motor-controller relationships in greater depth. And to provide additional data, 3E Vehicles tested two small motors, both on a dynamometer and in a vehicle, and the Eaton Corporation tested larger motors, using sophisticated instrumentation and digital processing techniques. All the motors tested were direct-current types. Of the separately excited types, seven were series wound and two were shunt wound. One self-excited permanent magnet type was also tested. Four of the series wound motors used brush shifting to obtain good commutation. In almost all cases, controller limitations constrained the test envelope so that the full capability of the motors could not be explored.

Improved motors for utility applications. Volume 2. Industry assessment study. Final report
Auxiliary drive motor failures in electric utility applications result in large repair costs and, energy replacement costs. In order to assess the motor reliability experience of the utility industry and identify specific problem areas, information or more than 4800 motors at 132 generating units owned by 56 utilities was collected. The computerized database encompasses all fuel sources, geographic factors and motor manufacturers. Analysis of the data, field interviews with utilities across the country and technical judgment were used to identify the major factors influencing motor reliability. In total, 1221 failures were reported which represents a rate of 4.6% failure per motor per year. Several utilities reported experience as good as 1 or 2% and others as poor as 12%. Although all manufacturers can supply reliable equipment for most applications, failures of specific components in certain specific applications appear to be associated with specific manufacturers. However, overall, 22% of all reported failures were attributed to winding failure and 13% to sleeve bearings. Numerous examples of misapplication were discovered such as the horizontal motor which was vertically mounted by an OEM, inadequately balanced hydraulic thrust loads in a packaged motor/pump system and inappropriate enclosure specified for a motor located outdoors.The internal procedures and practices of those utilities which had particularly low failure rate experience included such factors as, stringent specifications, objective purchasing policies, adequate record keeping and preventative maintenance programs. Auxiliary large drive motor failures are estimated to cost the average utility over $350,000 per unit per year for alternate energy source during outages. Future cooperative efforts by the manufacturers, the A and E firms, the OEM's and the utilities could significantly reduce this value.

Not a Babe in the Woods: Using MotorMaster Software to Make Sophisticated Electric Motor Purchase Decisions
Three-phase motors use more than half of all electricity in the United States. Energy efficient models are available in most motor classes in the 1 to 500 horsepower range, offering simple pay backs under two years. In practice, few motor buyers have performed an economic analysis, resulting in missed energy and dollar savings. MotorMaster software helps identify the best motor for a specific application. Its database of 9,000 motors includes the majority of three-phase motors sold in the United State. Performance information such as Full-Load RPM, torque and amperage rating identify models that meet specific design criteria. MotorMaster calculates operating costs and simple paybacks. This paper reviews the importance of proper electric motor selection and explains how MotorMaster software can be used to identify the most efficient, cost effective and reliable motor for each specific application.

Global forces shape the electricity industry
Whatever scenario for electricity comes to pass - one that emphasizes richness in energy supply or productivity in demand - expect to see increased complexity in the industry and its structures. Technology will be a key subversive element of this process of Schumpeterian creation and destruction. There are powerful global forces at work that are transforming whole economies and industries. Today`s electricity industry, with a century of tradition behind it, is also likely to be transformed in terms of its structure, competitive nature and the fuels that it uses. The electricity demand-Gross Domestic Product (GDP) relationship also stems from the increased share of electricity in energy markets. Overall, energy demand is declining relative to GDP, driven by increased efficiency and economic restructuring. Eventually (as indeed is already discernible in OECD countries) electricity demand will show the same characteristics.

Direct Lamination Cooling of Motors For Electric Vehicles
Current designs for electric motors use a housing that acts as both a structural support and as a method of cooling the stator and rotor. This approach to cooling is not as effective as possible because heat must flow from the rotor and stator through the housing to the cooling media. Because the housing must contain the coolant, it is also larger, heavier, and more expensive than necessary. This project develops a motor that uses a direct lamination cooling (DLC) system, passing coolant directly through the stator and eliminating the need for bulky housing, thereby improving heat transfer. Motor size could be reduced by up to 30-40%, mass by up to 20-30%, and cost by up to 30%. Phase I demonstrated that reliable lamination-to-lamination seals and reliable stack-to-manifold seals can be achieved using the methods identified. The addition of the selected sealants adds only slightly to the thermal resistance and pressure drop compared with unsealed counterparts. Phase II builds electric motors and inductors using the DLC method, obtain comparative performance data on the effectiveness of the method, and then obtain operational use data on these components through long term testing in a representative environment. The long-term testing will ensure that real world aspects of motor and inductor operation (including vibration, temperature cycling, and the presence of electrical and magnetic fields) do not degrade the seals such that leaking occurs or that the thermal performance degrades.

Dresser-Rand completed the preliminary aerodynamic flowpath of the volute and inlet design for the compressor section. This has resulted in considerable progress being made on the development of the compressor section and ultimately towards the successful integration of the IEMDC System design. Significant effort was put forth in the design of aerodynamic components which resulted in a design that meets the limits of aerodynamically induced radial forces previously established. Substantial effort has begun on the mechanical design of the compressor pressure containing case and other internal components. These efforts show progression towards the successful integration of a centrifugal compressor and variable speed electric motor ventilated by the process gas. All efforts continue to confirm the feasibility of the IEMDC system design. During the third quarter reporting period, the focus was to further refine the motor design and to ensure that the IEMDC rotor system supported on magnetic bearing is in compliance with the critical speed and vibration requirements of the API standards 617 and 541. Consequently specification to design magnetic bearings was developed and an RFQ to three magnetic bearing suppliers was issued. Considerable work was also performed to complete preliminary reports on some of the deliverable tasks under phase 1.0. These include specification for the VFD, RFQ for the magnetic bearings, and preliminary write-up for motor instrumentation and control schematic. In order to estimate motor efficiency at various operating points, plots of calculated motor losses, and motor cooling gas flow rates were also prepared. Preliminary evaluations of motor support concepts were performed via FEA to determine modal frequencies. Presentation was made at DOE Morgantown on August 12, 2003 to provide project status update. Preparations for the IEMDC motor-compressor presentation, at the GMRC conference in Salt Lake City to be held on October 5, 2003, were also started. Detailed calculations of cooling gas flow requirements for the motor and magnetic bearings, per several new operating points designated by DR, confirmed that the required gas flow was within the compressor design guidelines. Previous thrust load calculations had confirmed that the magnetic thrust bearing design load capacity of 6,000 lb. was sufficient to handle the net thrust load produced by the motor and compressor pressure loading. Thus the design data that has been generated, for the variable speed 10 MW 12,000 rpm motor, during the last three quarters, continue to confirm the feasibility of an efficient and robust motor design.

Electrical motor/generator drive apparatus and method
The present disclosure includes electrical motor/generator drive systems and methods that significantly reduce inverter direct-current (DC) bus ripple currents and thus the volume and cost of a capacitor. The drive methodology is based on a segmented drive system that does not add switches or passive components but involves reconfiguring inverter switches and motor stator winding connections in a way that allows the formation of multiple, independent drive units and the use of simple alternated switching and optimized Pulse Width Modulation (PWM) schemes to eliminate or significantly reduce the capacitor ripple current.

Electric top drives gain wide industry acceptance
Since its introduction, the top drive drilling system has gained acceptance as a productive and safe method for drilling oil and gas wells. Originally, the system was used mostly for offshore and higher cost land drilling, and it had to be installed as a permanent installation because of its enormous weight and size. Essentially, a top drive replaces the kelly and rotary table as the means of rotating drillpipe on oil, gas and geothermal rigs and is considered to be 15% to 40% more efficient than a kelly drive. Top drive systems allow the operator to drill and maintain directional orientation for triple stands and provide tripping efficiency because of the ability to ream and circulate with triple stands, to reduce the risk of stuck pipe or lost wells, and to improve well control and pipe handling safety. The paper describes electric top drives with DC motors, top drives with AC motors, top drives with permanent magnet motors, and top drives with permanent magnet brushless synchronous motors.

Instrument for analysis of electric motors based on slip-poles component
A new instrument is described for monitoring the condition and speed of an operating electric motor from a remote location. The slip-poles component is derived from a motor current signal. The magnitude of the slip-poles component provides the basis for a motor condition monitor, while the frequency of the slip-poles component provides the basis for a motor speed monitor. The result is a simple-to-understand motor health monitor in an easy-to-use package. Straightforward indications of motor speed, motor running current, motor condition (e.g., rotor bar condition) and synthesized motor sound (audible indication of motor condition) are provided. With the device, a relatively untrained worker can diagnose electric motors in the field without requiring the presence of a trained engineer or technician. 4 figs.

Restructuring the Philippine electric power industry
The Philippine electricity industry has shown it can change, and change quickly. In contrast with the crises and changes imposed on it in the past, the industry now has as opportunity to forge a progressive, forward-looking strategy, This opportunity is enhanced by the force of law - the Department of Energy Act of 1992 mandates privatization of the National Power Corporation (NPC) - and by the easing of the power crisis which has significantly diminished political interference. In order to position the industry for growth and rising investment requirements and to support the growing role of the Philippine economy in international markets, that strategy must address the structural deficiencies that continue to plague the industry. By addressing structural changes that need to be made now, it can build on the impetus gained from its privatization mandate to improve accountability, increase efficiency and reduce government risk.

Energy Conservation and Efficiency Improvement for the Electric Motors Operating in U.S. Oil Fields
Because of its versatility, electricity consumption continues to grow all over the world more rapidly than any other energy form. The portion of the United States' primary energy supply used as electricity has expanded from near zero at the turn of the century to 38 percent in 1987. Electric motors use as input about 64% of all electricity in the U.S. and many other countries. The cost of powering motors in the U.S. is estimated to be roughly $90 billion a year. In terms of primary energy input, motor energy use in the U.S. is comparable to all auto energy use. Electric motors are the largest users of energy in all mineral extraction activities. In oil fields, electric motors drive the pumping units used for lifting the oil and water to the surface. To find out actual efficiencies of operating motors in the oil fields, the University of Wyoming and the U.S. Department of Energy -Denver Support Office have been working for the last twelve months on two Naval Petroleum Reserve oil fields -one each in California and Wyoming. So far, actual motor loading of all operating oil fields motors has been determined by actual field measurements. We have also completed the analysis of economy of operation of existing motors and evaluating the candidate replacement motors. In this paper, we will present these results along with the methodologies and protocol developed for motor energy efficiency improvement in oil field applications.

Impact of New Federal Efficiency Performance Standards on the Industrial Motor Marketplace
The Energy Independence and Security Act of 2007 enacted new motor efficiency standards that will go into effect in December 2010. Previous motor efficiency standards, which were implemented as part of EPAct in 1992, caused some confusion within the motor marketplace. In part, this confusion lead to the development of NEMA's Premium® label, which has since helped guide motor purchasers to buy efficient motors. As a companion activity, the awareness program Motor Decisions Matter was established to encourage the replacement of motors with more efficient technology rather than the repair of old, inefficient motors. The motor marketplace now faces similar confusion as the new standards will soon be implemented. It is therefore incumbent upon industrial motor users to begin planning for these standards now, both by developing new motor management plans and by updating repair/replace decision criteria to reflect changes in efficiency and price for motor replacement options. At the same time, it is incumbent upon motor efficiency programs and policymakers to address the anticipated negative market behavior trends that will likely result from the new standards' implementation in the next few years.

Achieving A Long Term Business Impact by Improving the Energy Effectiveness and Reliability of Electric Motors
Over 100,000 electric motors drive the production equipment throughout a large chemical company. The energy-efficiency and reliability of these motors during their entire life have a decided impact on the company's manufacturing costs and production capability. The Corporate Motor Technology Team (CMTT) conceived and led a program to optimize the cost effectiveness and reliability of new motors and developed criteria to determine whether to repair or replace motors that fail. The higher energy efficiency of the electric motors offered by vendors today plays a crucial role in these decisions. The company's current motor specification, procurement, maintenance, repair and replacement practices are vastly improved and consistent across the corporation. The 1995 savings attributed to the higher energy efficiency of over 2000 motors installed the prior year amount to $570,000 and will continue to accrue year after year. So will the savings stemming from lower maintenance cost and reduced downtime.

During this reporting period, significant progress has been made towards the development of the IEMDC System design. Considerable effort was put forth by Curtiss-Wright EMD in the resolution of the technical issue of aerodynamically induced radial forces. This has provided a design basis with which to establish the radial magnetic bearing load capacity and the rotordynamic design. Dresser-Rand has made considerable progress on the flowpath design for the compressor section particularly on the volute and inlet aerodynamic design. All efforts show progression towards the successful integration of a centrifugal compressor and variable speed electric motor ventilated by the process gas. These efforts continue to confirm the feasibility of the IEMDC system design.

Ontario Hydro Motor Efficiency Study
Electric motors consume more than one-half of the electrical energy produced by Ontario Hydro. In the residential sector, the major motor load is for refrigerators and freezers while packaged equipment dominate the motor load in the commercial market. However, this paper concentrates on the industrial market since 76% of this market's load is motors. The poly phase integral horsepower motor is the "workhorse" of industry. The efficiency of the standard induction motor can be improved. The new "high efficiency" motor is described and the operating cost is compared to the standard motor. Payback for high efficiency motors is found to be about one year for continuous duty applications. Specific instructions are presented for use in industry.

Oil Field Electrical Energy Savings Through Energy-Efficient Motor Retrofits
The Wyoming Electric Motor Training and Testing Center (WEMTTC), in conjunction with the Department of Energy-Denver Support Office and the Naval Petroleum Reserve #3 (NPR-3), has conducted an extensive study of electric motor efficiency at the Reserve's oil field near Casper, Wyoming. As a result of this project, WEMTTC has developed a new test method for estimating an electric motor's operating efficiency, and the instrumentation to implement this test method. Using the new test method and instrumentation, several oversized or inefficient motors were replaced with new generation, high-efficiency motors, and the savings documented. This paper describes the test method and instrumentation developed by WEMTTC. The results obtained from the actual energy-efficient motor retrofits are also presented.

American Indian tribes and electric industry restructuring: Issues and opportunities
The US electric utility industry is undergoing a period of fundamental change that has significant implications for Native American tribes. Although many details remain to be determined, the future electric power industry will be very different from that of the present. It is anticipated that the new competitive electric industry will be more efficient, which some believe will benefit all participants by lowering electricity costs. Recent developments in the industry, however, indicate that the restructuring process will likely benefit some parties at the expense of others. Given the historical experience and current situation of Native American tribes in the US, there is good reason to pay attention to electric industry changes to ensure that the situation of tribes is improved and not worsened as a result of electric restructuring. This paper provides a review of electricity restructuring in the US and identifies ways in which tribes may be affected and how tribes may seek to protect and serve their interests. Chapter 2 describes the current status of energy production and service on reservations. Chapter 3 provides an overview of the evolution of the electric industry to its present form and introduces the regulatory and structural changes presently taking place. Chapter 4 provides a more detailed discussion of changes in the US electric industry with a specific focus on the implications of these changes for tribes. Chapter 5 presents a summary of the conclusions reached in this paper.

Public-policy responsibilities in a restructured electricity industry
In this report, we identify and define the key public-policy values, objectives, and actions that the US electricity industry currently meets. We also discuss the opportunities for meeting these objectives in a restructured industry that relies primarily on market forces rather than on government mandates. And we discuss those functions that governments might undertake, presumably because they will not be fully met by a restructured industry on its own. These discussions are based on a variety of inputs. The most important inputs came from participants in an April 1995 workshop on Public-Policy Responsibilities and Electric Industry Restructuring: Shaping the Research Agenda. Other sources of information and insights include the reviews of a draft of this report by workshop participants and others and the rapidly growing literature on electric-industry restructuring and its implications. One of the major concerns about the future of the electricity industry is the fate of numerous social and environmental programs supported by today`s electric utilities. Many people worry that a market-driven industry may not meet the public-policy objectives that electric utilities have met in the past. Examples of potentially at-risk programs include demand-side management (DSM), renewable energy, low-income weatherization, and fuel diversity. Workshop participants represented electric utilities, public utility commissions (PUCs), state energy offices, public-interest groups, other energy providers, and the research community.

Industrial Powerhouse Optimization in the Deregulated Electricity Marketplace
The State of Delaware deregulated the retail sale of electricity in 2002, enabling buyers to procure power on a real-time price schedule and sell excess generated power to the grid. This initiative has prompted industrial sites, especially those with on-site generation capability, to evaluate the benefits and risks of the deregulated market. Deregulation can offer significant potential savings to industrial customers. However, with this opportunity comes exposure to turbulent fluctuations in electricity prices, which can sometimes reach $1,000/MW-hr. If a customer is unprepared for high electricity prices, an entire year of electricity cost savings can quickly be erased. This paper describes how one industrial site evaluated the risks and benefits of electricity deregulation and implemented real-time optimization of the electricity make-buy decision.

Using MotorMaster to Track Motor Inventory and Analyze Purchasing Decisions
MotorMaster 4.0 can be a useful software package for electric motor management decisions in industrial facilities. To be successful, the MotorMaster database must be populated with detailed motor nameplate information. Georgia Tech worked with a large, motor intensive chemical manufacturing plant to collect motor nameplate information on motors 60 hp or larger and populate the motor database. Approximately 130 motors were identified and surveyed. The completed motor database is used to track maintenance actions and to analyze motor replacement options. The approach used to secure and enter motor nameplate data along with examples of purchasing analyses completed will be presented. The success of the MotorMaster software with large motors has convinced the firm to expand its use to smaller horsepower motors.

The changing structure of the electric power industry: An update
The U. S. electric power industry today is on the road to restructuring a road heretofore uncharted. While parallels can be drawn from similar journeys taken by the airline industry, the telecommunications industry, and, most recently, the natural gas industry, the electric power industry has its own unique set of critical issues that must be resolved along the way. The transition will be from a structure based on a vertically integrated and regulated monopoly to one equipped to function successfully in a competitive market. The long-standing traditional structure of the electric power industry is the result of a complex web of events that have been unfolding for over 100 years. Some of these events had far-reaching and widely publicized effects. Other major events took the form of legislation. Still other events had effects that are less obvious in comparison (e.g., the appearance of technologies such as transformers and steam and gas turbines, the invention of home appliances, the man-made fission of uranium), and it is likely that their significance in the history of the industry has been obscured by the passage of time. Nevertheless, they, too, hold a place in the underpinnings of today`s electric industry structure. The purpose of this report, which is intended for both lay and technical readers, is twofold. First, it is a basic reference document that provides a comprehensive delineation of the electric power industry and its traditional structure, which has been based upon its monopoly status. Second, it describes the industry`s transition to a competitive environment by providing a descriptive analysis of the factors that have contributed to the interest in a competitive market, proposed legislative and regulatory actions, and the steps being taken by the various components of the industry to meet the challenges of adapting to and prevailing in a competitive environment.

Environmental impacts of policies toward the rail- and motor-freight industries in the United States
Post-World War II policies toward motor freight encouraged monopolies and prevented competition among motor-freight companies. ICC controls upon rates were ceilings for rail freight, and floors for motor freight. The railroads' share of intercity freight declined drastically, and return on investment fell far below the opportunity cost of capital. Meanwhile motor-freight profits became excessive. Recent administrative and statutory deregulation measures have improved the competitive posture of the rail-freight industry, but policies continue to favor the motor-freight industry. The burgeoning shipment of intercity freight on heavy trucks has subjected the public to objectionable exposure to airborne carcinogens; noise in excess of tolerances; extensive and irreversible solid-waste insults; environmental impacts of unnecessary and excessive petroleum fuel consumption; an excessive death and injury toll; and a high incidence of environmental and human exposure to hazardous materials. By the decision criteria established, the water-quality and land-use impacts of the policy tilt could not be judged important. Recommendations for the amelioration of the policy imbalances are provided.

IRP and the electricity industry of the future: Workshop results
During the next several years, the U.S. electricity industry is likely to change dramatically. Instead of an industry dominated by vertically integrated companies that are regulated primarily by state public utility commissions, we may see an industry with many more participants and less regulation. These new participants may include independent power producers, entities that dispatch and control power plants on a real-time basis, entities that build and maintain transmission networks, entities that build and maintain distribution systems and also sell electricity and related to services to some retail customers, and a variety of other organizations that sell electricity and other services to retail customers. Because markets are intended to be the primary determinant of success, the role of state and federal regulators might be less than it has been in the past. During the past decade, utilities and state regulators have developed new ways to meet customer energy-service needs, called integrated resource planning (IRP). IRP provides substantial societal benefits through the consideration and acquisition of a broad array of resources, including renewables and demand-side management (DSM) programs as well as traditional power plants-, explicit consideration of the environmental effects of electricity production and transmission; public participation in utility planning; and attention to the uncertainties associated with different resources, future demands for electricity, and other factors. IRP might evolve in different ways as the electricity industry is restructured (Table S-I). To explore these issues, we ran a Workshop on IRP and the Electricity Industry of the Future in July 1994. This report presents the wisdom and experience of the 30 workshop participants. To focus discussions, we created three scenarios to represent a few of the many ways that the electricity industry might develop.

Electric Utility Industry Experience with Geomagnetic Disturbances
A geomagnetic disturbance (GMD) by its nature occurs globally and almost simultaneously. Severe geomagnetic storms cause problems for electric power systems. The vulnerability of electric power systems to such events has apparently increased during the last 10 to 20 years because power system transmission lines have become more interconnected and have increased in length and because power systems are now operated closer to their limits than in the past. In this report, the experience of electric utilities during geomagnetic storms is examined and analyzed. Measured data, effects on power system components, and power system impacts are considered. It has been found that electric power systems are susceptible to geomagnetically induced earth-surface potential gradients as small as a few (2 to 3) volts per kilometer, corresponding to a storm of K-6 intensity over an area of high earth resistivity. The causes and effects are reasonably well understood, but additional research is needed to develop a better understanding of solar-induced geomagnetic storms and the responses of power systems to these types of storms. A better understanding of geomagnetic storms and the power systems' responses to GMDs is needed so that mitigation measures can be implemented that will make power systems less susceptible to severe geomagnetic disturbances. A GMD caused by a large high-altitude nuclear detonation is similar in many ways to that of solar-induced geomagnetic storms except that a nuclear-caused disturbance would be much more intense with a far shorter duration.

Application of motor capacitors to improve facility power usage in the industrial setting
As deregulation of the electric power system in the United States unfolds, many customers are experiencing changes in their billing rate structure. Some face the addition of power factor penalty tariffs, and seek ways to minimize the added burden. The installation of entrance capacitor banks is the common response, but fails to take complete advantage of capacitor abilities. Other project designs exist that can harness these advantages to the full benefit of the customer. This work will show that distributing shunt capacitors in parallel with induction motors will elevate power factor and voltage, and also decrease ohmic losses in the wiring and protection devices that supply the motor. This reduction often produces a better overall economic solution due to energy savings. The distribution of capacitors at induction motors reduces the reactive current in the branch of the distribution system that supplies them. A reduction in the total current flowing to the motor along the distribution system results in smaller losses throughout the system. As losses diminish, the total real power drawn through the distribution system is lessened, and electric bills are reduced. This alternative to entrance capacitor banks is not as commonly implemented. A misconception that the resistance in facility distribution systems is relatively low has discouraged distributed motor capacitor installation for overall facility power factor correction, in favor of entrance capacitor banks. We will show that the resistance in the distribution system is higher than typically thought, that motor capacitors can exploit this fact, and can often economically outperform entrance capacitor banks which are terminated at the point of incoming utility power. Motor capacitors are not a new technology. They are commercially available off the shelf technology, suitable for power factor correction for induction motors. Distributed capacitors can be utilized for all significantly sized induction motors in a facility. The elevation in power factor and voltage, reduction in reactive current and real power are calculated, and trends are observed. The matter is considered from both the standpoint of engineering and economics to provide an integrated study.

Estimating Industrial Electricity Conservation Potential in the Pacific Northwest
The Pacific Northwest is undergoing a transition in electricity generation from a predominantly hydro system to a combined hydro-thermal system. The high marginal costs of thermal generation relative to the low-cost hydropower base have made the search for alternatives very important. The cost of many conservation measures is less than the cost of new generation. This paper describes the results of an evaluation of industrial electricity conservation measures. Using a detailed end-use data base on industrial electricity consumption in the Pacific North west (PNW), nine most electricity intensive industry groups at the 4-digit SIC level were selected. An engineering economic analysis of conservation measures was performed for representative plants in each industry group. The plant level conservation estimates were extrapolated to the 4-digit and 2-digit SIC levels. An analysis of the market penetration of each conservation measure was performed using a distribution of desired rates of return. Government programs to encourage electricity conservation were identified, and their costs and effectiveness were assessed. The paper describes the methodology and significant findings of the study.

Perspectives on the future of the electric utility industry
This report offers perspectives on the future of the electric utility industry. These perspectives will be used in further research to assess the prospects for Integrated Resource Planning (IRP). The perspectives are developed first by examining economic, political and regulatory, societal, technological, and environmental trends that are (1) national and global in scope and (2) directly related to the electric utility industry. Major national and global trends include increasing global economic competition, increasing political and ethnic strife, rapidly changing technologies, and increasing worldwide concern about the environment. Major trends in the utility industry include increasing competition in generation; changing patterns of electricity demand; increasing use of information technology to control power systems; and increasing implementation of environmental controls. Ways in which the national and global trends may directly affect the utility industry are also explored. The trends are used to construct three global and national scenarios- ``business as usual,`` ``technotopia future,`` and ``fortress state`` -and three electric utility scenarios- ``frozen in headlights,`` ``megaelectric,`` and ``discomania.`` The scenarios are designed to be thought provoking descriptions of potential futures, not predictions of the future, although three key variables are identified that will have significant impacts on which future evolves-global climate change, utility technologies, and competition. While emphasis needs to be placed on understanding the electric utility scenarios, the interactions between the two sets of scenarios is also of interest.

Electrical energy monitoring in an industrial plant
This thesis presents an investigation into the actual electrical energy and demand use of a large metal fabrication facility located in Houston, Texas. Plant selection and the monitoring system are covered. The influence of a low power factor on energy consumption and demand is covered, including installation of correction and the effect of increasing the power factor on demand and energy consumption block sizes. The installation of capacitance correction has increased the low power factor of this facility from the low 60% range to the mid-to-high 70% range. A method has been developed to predict savings based on precorrection monitored data in the event the exact amount of capacitance installed is unknown. Savings for the month of February, 1994, are found to be $1327.56. This method can be used as a diagnostic tool to determine the amount of active capacitance. In this plant, that amount was found to be 315 KVAC, which correlates reasonably well with the amount active in the plant. The monitoring installation is described, and other uses (besides that dealing with power factor correction) are covered. Those uses include monitoring plant and equipment performance and productivity, and savings due to missed opportunities for equipment turn off.

The Role of Electricity Pricing Policy in Industrial Siting Decisions
One of the many reasons why industries tend to co-locate in a general vicinity is the availability of factors of production. A manufacturer can achieve great savings if his production facility is located near his major raw material supplier. Since many intermediate industrial products are extremely energy intensive, the producer of these products must locate in areas where low cost energy resources are abundant. In many instances, therefore, the existence of these industries will serve as an anchor to other manufacturing industries. Furthermore, industry has great inertia in its locational preferences. It takes a long time to establish a patent of growth or decay. But once it is set in motion it is very difficult to change. Since the pricing policy of electricity plays a significant role in the siting decisions of energy intensive industries, it is therefore imperative for the policy makers to understand the long term impact of their policies. This paper will examine the current pricing policy of the electric utility industry in Texas.

Energy Conservation and Management for Electric Utility Industrial Customers
Comprehensive energy management assistance within the industrial section is currently being offered by a growing number of electric utilities as part of their efforts to - provide additonal demand side services to their industrial customers. One of the keys to these enhanced services is the availability of a unique Industrial Energy Conservation and Management (EC&M) computer model that can be used to evaluate the technical and economic benefits of installing proposed process related energy management systems within an industrial plant. Details of an EPRI sponsored pilot program are summarized and results presented on the use of the computer model to provide comprehensive EC&M system evaluations of potential energy management opportunities in HL&P's and other utility service areas. This capability is currently being offered to HL&P's industrial customers and is primarily concerned with identifying and evaluating possible process heat recovery and other energy management opportunities to show how a plant's energy related operating costs can be reduced.

Changing Structure of the Electric Power Industry: 1970-1991
The purpose of this report is to provide a comprehensive overview of the ownership of the U.S. electric power industry over the past two decades, with emphasis on the major changes that have occurred, their causes, and their effects.
Performance issues for a changing electric power industry
Extremely cold weather created record demands for electricity in the eastern two-thirds of the United States during the week of January 16, 1994. Fuel-related problems, mostly the result of transportation constraints resulting from ice accumulation on roads and water-ways, and unexpected generating capacity outages at utilities and nonutilities resulted in demand not being met. Some utilities asked nonessential customers along with State governments and a portion of the Federal Government to shut down. Two electric control areas, the Pennsylvania-New Jersey-Maryland Interconnection (PJM) and Virginia Electric & Power Company (VEPCO), instituted rolling blackouts. This disturbance was reported widely in the press and, along with other disturbances, peaked renewed interest in the reliability of the electric power system. The renewed interest in reliability has coincided with substantial changes that are beginning to occur in the structure and competitiveness of the electric power industry. Juxtaposing the question of reliability and the issue of changing industry structure leads to the central concern of this report: What effect, if any, will the changing structure of the industry have on the reliability of the system?

Electric utility restructuring and the California biomass energy industry
A shock jolted the electric power industry in April 1994, when the California Public Utilities Commission (CPUC) announced its intention to restructure the industry. The proposal, commonly referred to as retail wheeling, is based on the principle that market deregulation and competition will bring down the cost of electricity for all classes of customers. It would effectively break up the monopoly status of the regulated utilities and allow customers to purchase electricity directly from competing suppliers. According to the original CPUC proposal, cost alone would be the basis for determining which generating resources would be used. The proposal was modified in response to public inputs, and issued as a decision at the end of 1995. The final proposal recognized the importance of renewables, and included provisions for a minimum renewables purchase requirement (MRPR). A Renewables Working Group convened to develop detailed proposals for implementing the CPUC`s renewables program. Numerous proposals, which represented the range of possible programs that can be used to support renewables within the context of a restructured electric utility industry, were received.

A Novel Approach to Determining Motor Load
Properly sized electric motors are essential if industrial plant efficiency is to be optimized and energy costs minimized. Because of the difficulty in making power measurements on three phase motors, loading is rarely, if ever, checked. A simple indication of motor load can be achieved by measuring operating speed because speed and load are almost linearly related. The decrease in motor speed from no load conditions, referred to as slip, can be determined with a non-contact, optical tachometer. Field measurements of motor slip were conducted at a textile plant to quantify motor load conditions. To verify the relationship between operating speed and load, measurements of motor power consumption on a representative number of motors were also conducted. The results of the motor survey, including number of motors, size, and load, are summarized in this paper along with an estimate of the savings from replacing oversized motors.

Evaluating High Efficiency Motor Retrofit
In the petrochemical and refining Industries, and most manufacturing plants, the reliable operation of AC motors always has been crucial to the continuous operation of the process. Now, the cost of operating these motors has also become a significant factor. Engineers Involved In motor specification can help lower plant operating costs and reduce electrical energy consumption dramatically by a relatively simple technique: retrofit of existing, standard-efficiency motors with new, high efficiency models. This article demonstrates strong reasons for motor retrofit, and explains step-by step how process and manufacturing engineering personnel can fully evaluate a retrofit decision.

PM Motor Parametric Design Analyses for Hybrid Electric Vehicle Traction Drive Application: Interim Report
The Department of Energy's (DOE) Office of FreedomCAR (Cooperative Automotive Research) and Vehicle Technologies has a strong interest in making rapid progress in permanent magnet (PM) machine development. The program is directing various technology development projects that will advance the technology and lead to request for proposals (RFP) for manufacturer prototypes. This aggressive approach is possible because the technology is clearly within reach and the approach is deemed essential, based on strong market demand, escalating fuel prices, and competitive considerations. In response, this study began parallel development paths that included a literature search/review, development and utilization of multiple parametric models to determine the effects of design parameters, verification of the modeling methodology, development of an interior PM (IPM) machine baseline design, development of alternative machine baseline designs, and cost analyses for several candidate machines. This interim progress report summarizes the results of these activities as of June 2004. This report provides background and summary information for recent machine parametric studies and testing programs that demonstrate both the potential capabilities and technical limitations of brushless PM machines (axial gap and radial gap), the IPM machine, the surface-mount PM machines (interior or exterior rotor), induction machines, and switched reluctance machines. The FreedomCAR program, while acknowledging the progress made by Oak Ridge National Laboratory, Delphi, Delco-Remy International, and others in these programs, has redirected efforts toward a ''short path'' to a marketable and competitive PM motor for hybrid electric vehicle traction applications. The program has developed a set of performance targets for the type of traction machine desired. The short-path approach entails a comprehensive design effort focusing on the IPM machine and meeting the performance targets. The selection of the IPM machine reflects industry's confidence in this market-proven design that exhibits a power density surpassed by no other machine design.

Impact of Electricity Deregulation on Industrial Assessment Strategies
This paper explores many of the changes in typical industrial assessment recommendations, which have resulted from deregulation of the electric and gas industries. While anticipating that energy efficiency would almost always be a good idea, changes in rate structures and indeed the very nature of how energy is purchased can put some energy efficiency technologies outside of normal economically acceptable ranges. A major focus will be changes in and the elimination of time-of-use rates for electricity. An entire generation of DSM'ers (people working in "Demand-Side Management") worked under the principle that there was economic benefit to load leveling. Time-of-use rates are changing throughout the country and in many cases disappearing. Bulk purchase of electricity has even resulted in cases where, with minimum consumption requirements, industrial plants need to find ways to increase their electrical use to avoid penalties. Energy storage devices including thermal energy storage must be re-examined in terms of this new paradigm. There are applications where they are advisable, but for different reasons then demand management. Another area of particular interest is fuel selection, multiply fuel capability, and contracting. An industrial assessment at two neighboring plants can result in entirely different recommendations based on how energy is purchased and billed. In many cases, an industrial plant may be better off spending resources on energy purchasing agents as opposed to anything like an energy efficiency project. Onsite generation of power and the changing rationales for its adoption has also experienced big changes. Energy security is becoming a strong motivation for industrial plants, options are increased, and third party funding is also starting to appear. Intermediate solutions like gas driven compressors bring these two areas together and leave industrial clients with more options but often more confusion than ever before. Finally, the paper discusses some of the new challenges facing an industrial assessment team in terms of information gathering. It is becoming necessary to examine many possible energy purchase options and each has ramifications on energy efficiency projects. Use of the Internet, computer tools and other information sources is presented.

Phase 1 STTR flywheel motor/alternator for hybrid electric vehicles. CRADA final report
Visual Computing Systems (VCS) and the Oak Ridge National Laboratory (ORNL) have teamed, through a Phase 1 Small Business Technology Transfer (STTR) grant from the US Department of Energy (DOE), to develop an advanced, low-cost motor/alternator drive system suitable for Flywheel Energy Storage (FES) applications. During Phase 1, system performance and design requirements were established, design concepts were generated, and preliminary motor/alternator designs were developed and analyzed. ORNL provided mechanical design and finite element collaboration and Lynx Motion Technology, a spin-off from VCS to commercialize their technology, constructed a proof-of-concept axial-gap permanent magnet motor/alternator that employed their Segmented Electromagnetic Array (SEMA) with a survivable design speed potential of 10,000 rpm. The VCS motor/alternator was successfully tested in ORNL`s Motor Test Tank using an ORNL inverter and ORNL control electronics. It was first operated as an unloaded motor to 6,000 rpm and driven as an unloaded generator to 6,000 rpm. Output from the generator was then connected to a resistance bank, which caused the loaded generator to decelerate to 3,860 rpm where data was collected. After about 4-1/2 minutes, the test was terminated because of an impact noise. Subsequent inspection and operation at low speeds did not reveal the source of the noise. Electrical performance of the motor was excellent, encouraging continued development of this technology. Phase 2 efforts will focus on further design development and optimization, manufacturing development and prototype construction, testing, and evaluation.

The new electricity industry: What`s at stake?
There is enough potential for value creation and growth in the emerging electric industry to overcome the very significant downside facing today`s utilities. In the transition to competition, electricity customers will gain lower prices, and new or retooled competitors will take market share. To emerge a winner, utilities will have to move quickly on three fronts-strategic, organizational, and regulatory. Market forces, now being accommodated by deregulation, are remaking the electric utility industry. As in banking and telecommunications before it, this industry is now in the early stages of a complete transformation. There will be mergers and massive consolidation. There will be new competitors who will redefine the economics and competitive dynamics of the business, as MCI did in telecom and Fidelity has done in banking. As in banking and telecom, there will be traditional players, like Citibank or ATT, who make and actually shape the transition, and others who dwindle, vanish or are subsumed. The winners will create significant value for their shareholders. The once vertically integrated electric industry will fragment into three distinct, but linked, businesses - generation, wires and power services - plus a dispatch function. Each will have its own competitors and particular competitive dynamics. Generation will be a highly competitive, cost-based commodity business. Wires businesses, comprised of transmission and distribution functions, will be regulated, open access networks. Power services, encompassing wholesale and retail commodity sales and including other energy and non-energy products, will be provided by a third set of services competitors. Scheduling and dispatch, grid control and price settlements will be provided by independent, regulated entities and are outside the scope of this article.

Industrial Approaches to Reducing Energy Costs in a Restructuring Electric Industry
Electric restructuring, currently proposed in California and being reviewed elsewhere, can produce many opportunities for large companies to reduce their electricity costs. As the electricity market changes, electric utilities and other potential suppliers are likely to develop a portfolio of options and creative pricing to attract customers in a competitive market. In attempting to be "energy neutral," i.e., to be indifferent to energy costs in one state or utility service area versus another, many companies are looking at a corporate approach to energy procurement, similar to the procurement of other products. Industrial customers may be looking for regional or even national energy suppliers for their facilities. Electric utilities, in an attempt to be competitive and retain customers, will likely work to be this regional or national energy supplier. The expectation will be that these suppliers can offer competitive pricing and a portfolio of options from which to choose. These options may resemble those that have developed in the natural gas market as a result of restructuring in the fuels industry.

Electricity distribution industry restructuring, electrification, and competition in South Africa
This paper reviews the status of the South African electricity supply industry (ESI) and proposals for reorienting and restructuring it. South Africa has been intensely examining its ESI for more than 4 years in an effort to determine whether and how it should be restructured to best support the country`s new economic development and social upliftment goals. The debate has been spirited and inclusive of most ESI stakeholders. The demands on and expectations for the ESI are many and varied. The debate has reflected this diversity of interests and views. In essence, however, there is a consensus on what is expected of the industry, namely, to extend provision of adequate, reliable, and affordable electricity service to all citizens and segments of the economy. This means a large-scale electrification program to reach as many of the nearly 50% of households currently without electricity service as soon as possible, tariff reform to promote equity and efficiency, and the upgrading of service quality now being provided by some of the newly consolidated municipal authorities. The issues involved are how best to achieve these results within the context of the national Reconstruction and Development Program, while accounting for time and resource constraints and balancing the interests of the various parties.

Discrimination among mechanical fault types in induction motors using electrical measurements
Rotating machine failures are a major cause of downtime in a wide variety of industrial processes and are a burden on maintenance personnel and facilities. Some of these failures occur suddenly and are seemingly unpredictable. However, the overwhelming majority develop slowly over time and produce characteristic warning signs. A system capable of detecting and diagnosing these incipient faults before they become critical would significantly reduce downtime and serve to facilitate maintenance and repair of these machines. The ability to accurately distinguish between different types of incipient faults would be a critical aspect of such a system. In this research, a model-based method for diagnosing motor faults is examined and tested using two squirrel-cage AC induction motors with staged fault conditions. The proposed method involves the multi-resolution signal analysis of the current residuals. These residuals are generated by comparing the measured motor current with the current predicted by a recurrent neural network. The frequency content of the distortion of the residuals is used to identify the type of fault present. Although "steady-state" conditions are examined exclusively in this research, the nonstationarities of the current signals are sufficient to warrant the use of multi-resolution analysis. The fault diagnosis system is tested using data taken from an 800 hp motor and a 3 hp motor. The method is successful in identifying residual distortion in the frequency range expected for broken-bar faults. Because the magnitude of the distortion grows with increasing fault severity, the method is also useful for evaluating fault severity for broken-bar faults. However, the current distortions caused by rotor eccentricities and damaged bearings are too small to be identified in a statistically significant manner using this approach. Nevertheless, this research demonstrates the feasibility of a general method by which the characteristic frequencies produced by a particular type of fault can be identified in the output of a system.

What Does Industry Expect From An Electrical Utility
The electric utility industry is an important supplier to Union Carbide and as such must become a proactive participant in our quality programs which are aimed at continuous improvement in everything we do. The essential ingredients in the supplier quality programs we are developing include: 1. Performance and Delivery, 2. Conformance, 3. Responsiveness, 4. Communications, 5. Supplier Quality Efforts. The electric utility supplying each of our locations is our partner at that location. We do not have the same degree of flexibility to change electricity suppliers that we might have with other suppliers of goods and services. In order for our partnerships to work we must get to know each other better. We need to understand the other guy's problems and then find ways to do business that are mutually beneficial to both of us. At Union Carbide our total quality process has started at the top of the corporation and is working its way throughout the organization. Our supplier quality programs are now beginning to take shape and we are relying upon our electric utility suppliers to become active in the final design and implementation of these programs.

Strategies to address transition costs in the electricity industry
Transition costs are the potential monetary losses that electric- utility shareholders, ratepayers, or other parties might experience because of structural changes in the electricity industry. Regulators, policy analysts, utilities, and consumer groups have proposed a number of strategies to address transition costs, such as immediately opening retail electricity markets or delaying retail competition. This report has 3 objectives: identify a wide range of strategies available to regulators and utilities; systematically examine effects of strategies; and identify potentially promising strategies that may provide benefits to more than one set of stakeholders. The many individual strategies are grouped into 6 major categories: market actions, depreciation options, rate-making actions, utility cost reductions, tax measures, and other options. Of the 34 individual strategies, retail ratepayers have primary or secondary responsibility for paying transition costs in 19 of the strategies, shareholders in 12, wheeling customers in 11, taxpayers in 8, and nonutility suppliers in 4. Most of the strategies shift costs among different segments of the economy, although utility cost reductions can be used to offset transition costs. Most of the strategies require cooperation of other parties, including regulators, to be implemented successfully; financial stakeholders must be engages in negotiations that hold the promise of shared benefits. Only by rejecting ``winner-take-all`` strategies will the transition-cost issue be expeditiously resolved.

Transition-cost issues for a restructuring US electricity industry
Utilities regulators can use a variety of approaches to calculate transition costs. We categorized these approaches along three dimensions. The first dimension is the use of administrative vs. market procedures to value the assets in question. Administrative approaches use analytical techniques to estimate transition costs. Market valuation relies on the purchase price of particular assets to determine their market values. The second dimension concerns when the valuation is done, either before or after the restructuring of the electricity industry. The third dimension concerns the level of detail involved in the valuation, what is often called top-down vs. bottom-up valuation. This paper discusses estimation approaches, criteria to assess estimation methods, specific approaches to estimating transition costs, factors that affect transition-cost estimates, strategies to address transition costs, who should pay transition costs, and the integration of cost recovery with competitive markets.

Motor torque compensation of an induction electric motor by adjusting a slip command during periods of supposed change in motor temperature
The present invention maintains constant torque in an inverter driven AC induction motor during variations in rotor temperature. It is known that the torque output of a given AC induction motor is dependent upon rotor temperature. At rotor temperatures higher than the nominal operating condition the rotor impedance increases, reducing the rotor current and motor torque. In a similar fashion, the rotor impedance is reduced resulting in increased rotor current and motor torque when the rotor temperature is lower than the nominal operating condition. The present invention monitors the bus current from the DC supply to the inverter and adjusts the slip frequency of the inverter drive to maintain a constant motor torque. This adjustment is based upon whether predetermined conditions implying increased rotor temperature or decreased rotor temperature exist for longer that a predetermined interval of time.

Study of the Advantages of Internal Permanent Magnet Drive Motor with Selectable Windings for Hybrid-Electric Vehicles
This report describes research performed on the viability of changing the effectively active number of turns in the stator windings of an internal permanent magnet (IPM) electric motor to strengthen or weaken the magnetic fields in order to optimize the motor's performance at specific operating speeds and loads. Analytical and simulation studies have been complemented with research on switching mechanisms to accomplish the task. The simulation studies conducted examine the power and energy demands on a vehicle following a series of standard driving cycles and the impact on the efficiency and battery size of an electrically propelled vehicle when it uses an IPM motor with turn-switching capabilities. Both full driving cycle electric propulsion and propulsion limited starting from zero to a set speed have been investigated.

Rural electric cooperatives and the cost structure of the electric power industry: A multiproduct analysis
Since 1935, the federal government of the United States has administered a program designed to make electricity available to rural Americans. This dissertation traces the history of the rural electrification program, as well as its costs. While the Congress intended to simply provide help in building the capital structure of rural electric distribution systems, the program continues to flourish some 35 years after these systems first fully covered the countryside. Once the rural distribution systems were built, the government began to provide cooperatives with billions of dollars in subsidized loans for the generation of electric power. Although this program costs the taxpayers nearly $1 billion per year, no one has ever tested its efficacy. The coops' owner/members do not have the right to trade their individual ownership shares. The RECs do not fully exploit the scale and scope economies observed in the investor-owned sector of this industry. This dissertation compares the relative productive efficiencies of the RECs and the investor-owned electric utilities (IOUs) in the United States. Using multiproduct translog cost functions, the estimated costs of cooperatives are compared to those of IOUs in providing identical output bundles. Three separate products are considered as outputs: (1) wholesale power; (2) power sold to large industrial customers; and (3) power sold to residential and commercial customers. It is estimated that, were the RECs forced to pay market prices for their inputs, their costs would exceed those incurred by the IOUs by about 24 percent. Several policy recommendations are made: (1) the RECs should be converted to stockholder-owned, tax-paying corporations; (2) the government should discontinue its subsidized loan program; (3) the government should sell its hydroelectric power at market prices, nullifying the current preference given to cooperatives and municipal distributors in the purchase of this currently underpriced power.

A Soft-Switching Inverter for High-Temperature Advanced Hybrid Electric Vehicle Traction Motor Drives
The state-of-the-art hybrid electric vehicles (HEVs) require the inverter cooling system to have a separate loop to avoid power semiconductor junction over temperatures because the engine coolant temperature of 105?C does not allow for much temperature rise in silicon devices. The proposed work is to develop an advanced soft-switching inverter that will eliminate the device switching loss and cut down the power loss so that the inverter can operate at high-temperature conditions while operating at high switching frequencies with small current ripple in low inductance based permanent magnet motors. The proposed tasks also include high-temperature packaging and thermal modeling and simulation to ensure the packaged module can operate at the desired temperature. The developed module will be integrated with the motor and vehicle controller for dynamometer and in-vehicle testing to prove its superiority. This report will describe the detailed technical design of the soft-switching inverters and their test results. The experiments were conducted both in module level for the module conduction and switching characteristics and in inverter level for its efficiency under inductive and dynamometer load conditions. The performance will be compared with the DOE original specification.

Electric Utility Industrial DSM and M&V Program
BC Hydro is an electric utility with a service area covering over 95% of the province of British Columbia in Canada. Power Smart is BC Hydro's demand-side-management (DSM) division. Power Smart develops, operates and manages various DSM programs for residential, commercial and industrial customers. The Power Smart Partners Program (PSP) is the premier demand-side management program for BC Hydro's large commercial and industrial non-transmission class customers. It is a direct energy acquisition program that is based on a partnering approach with BC Hydro's business customers. A customer that commits to being a Power Smart Partner gains access to financial support and assistance with the identification and implementation of electricity savings projects. A direct financial incentive is provided to lower customers' funding requirements and to improve the payback and/or investment criteria for energy efficiency projects. Projects are evaluated against established criteria set forth by BC Hydro. Projects which prove to be the most cost-effective on a $/kWh basis receive funds. For transmission-voltage customers, BC Hydro has recently implemented a new tariff designed to encourage energy reduction. The new tariff is an inclining block tariff and is known as the Stepped Rate. The customer's consumption is compared against their Customer Baseline Load (CBL). The first 90% of the customer's consumption is billed at a Tier 1 rate. The remaining consumption is billed at a Tier 2 rate, approximately two times the Tier 1 rate. There are mechanisms in place to adjust the customer's CBL to account for activities such as customer-funded demand-side-management projects and customer plant expansion projects. This paper will discuss BC Hydro's M&V program in terms of the process, operations and M&V results to date for the PSP. In addition, the paper will discuss the new Stepped Rate tariff intricacies in terms of CBL setting, CBL adjustments and transmission customer Impact Study guideline requirements.

Subcontract Report: Final Report on Assessment of Motor Technologies for Traction Drives of Hybrid and Electric Vehicles (Subcontract #4000080341)
Currently, interior permanent magnet (IPM) motors with rare-earth (RE) magnets are almost universally used for hybrid and electric vehicles (EVs) because of their superior properties, particularly power density. However, there is now a distinct possibility of limited supply or very high cost of RE magnets that could make IPM motors unavailable or too expensive. Because development of electric motors is a critical part of the U.S. Department of Energy (DOE) Advanced Power Electronics and Motors activity, DOE needs to determine which options should be investigated and what barriers should be addressed. Therefore, in order to provide a basis for deciding which research topics should be pursued, an assessment of various motor technologies was conducted to determine which, if any, is potentially capable of meeting FreedomCAR 2015 and 2020 targets. Highest priority was given to IPM, surface mounted permanent magnet (SPM), induction, and switched reluctance (SR) motors. Also of interest, but with lesser emphasis, were wheel motors, multiple-rotor motors, motors with external excitation, and several others that emerged from the assessment. Cost and power density (from a design perspective, the power density criterion translates to torque density) are emerging as the two most important properties of motors for traction drives in hybrid and EVs, although efficiency and specific power also are very important. The primary approach for this assessment involved interviews with original equipment manufacturers (OEMs), their suppliers, and other technical experts. For each technology, the following issues were discussed: (1) The current state-of-the-art performance and cost; (2) Recent trends in the technology; (3) Inherent characteristics of the motor - which ones limit the ability of the technology to meet the targets and which ones aid in meeting the target; (4) What research and development (R&D) would be needed to meet the targets; and (5) The potential for the technology to meet the targets. The interviews were supplemented with information from past Oak Ridge National Laboratory (ORNL) reports, previous assessments that were conducted in 2004, and literature on magnet technology. The results of the assessment validated the DOE strategy involving three parallel paths: (1) there is enough of a possibility that RE magnets will continue to be available, either from sources outside China or from increased production in China, that development of IPM motors using RE magnets should be continued with emphasis on meeting the cost target. (2) yet the possibility that RE magnets may become unavailable or too expensive justifies efforts to develop innovative designs for permanent magnet (PM) motors that do not use RE magnets. Possible other magnets that may be substituted for RE magnets include samarium-cobalt (Sm-Co), Alnico, and ferrites. Alternatively, efforts to develop motors that do not use PMs but offer attributes similar to IPM motors also are encouraged. (3) New magnet materials using new alloys or processing techniques that would be less expensive or have comparable or superior properties to existing materials should be developed if possible. IPM motors are by far the most popular choice for hybrid and EVs because of their high power density, specific power, and constant power-speed ratio (CPSR). Performance of these motors is optimized when the strongest possible magnets - i.e., RE neodymium-iron-boron (NdFeB) magnets - are used.

Industrial Potential for Substitution of Electricity for Oil and Natural Gas
The prospect of natural gas decontrol as well as uncertainties of gas and other fuel supplies have aroused interest in electric processes among industrial officials. Where there is ample electric power supply at reasonable cost, an opportunity exists for selected industry groups to make cost-effective conversions to electric processes. Technological advances in high-efficiency electric process equipment increase the potential for energy substitution. This, in turn, is changing the market outlook for electric utilities. By and large, energy substitution decisions will be based on their economic and technical feasibility. In view of projections of the long-term price escalations of oil and natural gas, the economic of choosing electricity are looking good at present. This paper will describe certain industrial applications where the substitution of electricity for oil and natural gas appears economically advantageous.

Transistors for Electric Motor Drives: High-Performance GaN HEMT Modules for Agile Power Electronics
ADEPT Project: Transphorm is developing transistors with gallium nitride (GaN) semiconductors that could be used to make cost-effective, high-performance power converters for a variety of applications, including electric motor drives which transmit power to a motor. A transistor acts like a switch, controlling the electrical energy that flows around an electrical circuit. Most transistors today use low-cost silicon semiconductors to conduct electrical energy, but silicon transistors don't operate efficiently at high speeds and voltage levels. Transphorm is using GaN as a semiconductor material in its transistors because GaN performs better at higher voltages and frequencies, and it is more energy efficient than straight silicon. However, Transphorm is using inexpensive silicon as a base to help keep costs low. The company is also packaging its transistors with other electrical components that can operate quickly and efficiently at high power levels—increasing the overall efficiency of both the transistor and the entire motor drive.

Electricity in lieu of nautral gas and oil for industrial thermal energy: a preliminary survey
In 1974, industrial processors accounted for nearly 50% of the nation's natural gas consumption and nearly 20% of its consumption of petroleum. This report is a preliminary assessment of the potential capability of the process industries to substitute utility-generated electricity for these scarce fuels. It is tacitly assumed that virtually all public utilities will soon be relying on coal or nuclear fission for primary energy. It was concluded that the existing technology will permit substitution of electricity for approximately 75% of the natural gas and petroleum now being consumed by industrial processors, which is equivalent to an annual usage of 800 million barrels of oil and 9 trillion cubic feet of gas at 1974 levels. Process steam generation, used throughout industry and representing 40% of its energy usage, offers the best near-term potential for conversion to electricity. Electric boilers and energy costs for steam are briefly discussed. Electrically driven heat pumps are considered as a possible method to save additional low-grade energy. Electrical reheating at high temperatures in the primary metals sector will be an effective way to conserve gas and oil. A wholesale shift by industry to electricity to replace gas and oil will produce impacts on the public utilities and, perhaps, those of a more general socio-economic nature. The principal bar to large-scale electrical substitution is economics, not technology. 174 references.

Region-specific study of the electric utility industry. Phase I, final report
This report describes the financial background of the electric utility industry in VACAR, reports on the present condition of the industry and then assesses the future of this industry. The Virginia-Carolinas subregion (VACAR) of the Southeastern Electric Reliability Council (SERC) was selected for this regional study because of its cooperativeness and its representative mix of powerplants, for example coal, hydro, nuclear, oil. It was found that the supply of future economic electricity is in jeopardy because of the regulatory process, the increasing risk associated with large scale generating stations and the weakening of the nuclear option. A number of options for the future were considered, including deregulation, government ownership and retaining the present system with modifications. The option selected to improve the present condition of the electricity industry was to make the present system work. The present system is sound, and with modifications, problems could be solved within the existing framework. 8 figs., 4 tabs.

Copper in the Rotor for Lighter, Longer Lasting Motors
This paper reviews the advantages of substituting die-cast copper for aluminum in the motor rotor. This advance in motor technology has been long sought by the motor industry but short die life due to the high melting point of copper frustrated attempts to manufacture by pressure die casting. The nickel-base alloy hot die technology developed to solve the manufacturing problem is briefly reviewed. Development work done prior to the present program and commercial motors derived from that work have focused on the increased electrical energy efficiency achievable by using copper with its higher electrical conductivity in the rotor. Performance characteristics of example industrial motors are presented. Modification of the conductor bar shape to control in-rush current and starting torque to accommodate copper in the rotor will be discussed. Modeling by motor manufacturers has shown that by using copper in the rotor, a lighter motor than an aluminum rotor motor at the same efficiency can be built. An example of weight savings calculated for a 15 Hp (11 kW) motor is presented. Data presented here show that motors with copper rotors run cooler. Industry experience shows that cooler operation translates to reduced maintenance costs, improved reliability and longer motor life.

Ways Electricity Can Be Used To Replace Fossil Fuels in The French Chemical Industry
France energy policy for the year 1990 foresees the following breakdown between various energy sources : renewable sources (including hydraulic) : 11%, coal + natural gas : 30.5%, nuclear : 26.5%, oil : 32%. The electricity will be produced mainly by nuclear: 66 % and by hydraulic : 14%, coal : 15%, fuel oil : 5%. Electricity and coal will then be the two major energy sources at the disposal of the French Industry. The new tariff structure of electricity proposed by Electricite de France will be given briefly explaining why and how electricity used to replace fossil fuels are seriously considered by the French Chemical Industry and by Rhone-Poulenc. Examples of various new utilisations of electrical equipment in chemical processes (thermal, heat pumps, filtration, electrolysis . . .) will be given. Emphasis will be put on research and development for new equipment and on the importance of good information and relationship between utilities suppliers, manufacturers and industrial consumers.

Performance Evaluation of a Cascaded H-Bridge Multi Level Inverter Fed BLDC Motor Drive in an Electric Vehicle
The automobile industry is moving fast towards Electric Vehicles (EV); however this paradigm shift is currently making its smooth transition through the phase of Hybrid Electric Vehicles. There is an ever-growing need for integration of hybrid energy sources especially for vehicular applications. Different energy sources such as batteries, ultra-capacitors, fuel cells etc. are available. Usage of these varied energy sources alone or together in different combinations in automobiles requires advanced power electronic circuits and control methodologies. An exhaustive literature survey has been carried out to study the power electronic converter, switching modulation strategy to be employed and the particular machine to be used in an EV. Adequate amount of effort has been put into designing the vehicle specifications. Owing to stronger demand for higher performance and torque response in an EV, the Permanent Magnet Synchronous Machine has been favored over the traditional Induction Machine. The aim of this thesis is to demonstrate the use of a multi level inverter fed Brush Less Direct Current (BLDC) motor in a field oriented control fashion in an EV and make it follow a given drive cycle. The switching operation and control of a multi level inverter for specific power level and desired performance characteristics is investigated. The EV has been designed from scratch taking into consideration the various factors such as mass, coefficients of aerodynamic drag and air friction, tire radius etc. The design parameters are meant to meet the requirements of a commercial car. The various advantages of a multi level inverter fed PMSM have been demonstrated and an exhaustive performance evaluation has been done. The investigation is done by testing the designed system on a standard drive cycle, New York urban driving cycle. This highly transient driving cycle is particularly used because it provides rapidly changing acceleration and deceleration curves. Furthermore, the evaluation of the system under fault conditions is also done. It is demonstrated that the system is stable and has a ride-through capability under different fault conditions. The simulations have been carried out in MATLAB and Simulink, while some preliminary studies involving switching losses of the converter were done in PSIM.

Industrial-Load-Shaping: The Practice of and Prospects for Utility/Industry Cooperation to Manage Peak Electricity Demand
Load-management programs designed to reduce demand for electricity during peak periods are becoming increasingly important to electric utilities. For a growing number of utilities, however, such peak-reduction programs don't go far enough in the face of new problems and challenges, and hence are proving ineffective or counterproductive. For example, many of a utility's largest customers--especially industrial customers who may be "locked into" seemingly inflexible process activities--have limited ability to respond to load-management programs that employ price signals as a central peak-reduction tool. Moreover, utilities in general are finding that vigorous efforts to reduce electric load can result in underutilization of base-load generating facilities. In these and other instances, "load-shaping," which emphasizes a shift of electric load or demand from peak to off-peak periods and provides for greater customer flexibility, may be a more effective strategy. This paper explains the need for and presents the components of a load-shaping program, and describes Pacific Gas and Electric Company's (PGandE) recent experience in designing and pursuing an industrial-load-shaping program. The paper also outlines important obstacles and opportunities likely to confront other utilities and industrial customers interested in working together to develop such programs.

Assessment of factors affecting industrial electricity demand. Final report (revision version)
In Chapter 2, we identify those factors affecting the industrial product mix - taste, relative output prices, and relative input prices - and isolate several determinants which have not been adequately accounted for to date in industrial electricity demand forecasts. We discuss how the lower energy prices of foreign producers affect domestic producers and how the growth in the number of substitutes for intermediate products such as steel and aluminum with plastics and composites affects the composition of production and, hence, the demand for electricity. We also investigate how the changing age structure of the population brought on by the baby boom could change the mix of outputs produced by the industrial sector. In Chapter 3, we review the history of the 1970s with regard to changes in output mix and the manufacturing demand for electricity, and with regard to changes in the use of electricity vis-a-vis the other inputs in the production process. In Chapter 4, we generate forecasts using two models which control for efficiency changes, but in different ways. In this chapter we present the sensitivity of these projections using three sets of assumptions about product mix. The last chapter summarizes our results and draw from those results implications regarding public policy and industrial electricity demand. Two appendices present ISTUM2 results from selected electricity intensive industries, describes the ISTUM and ORIM models.

Specification, estimation, and forecasts of industrial demand and price of electricity
This paper discusses the specification of electricity-demand and price equations for manufacturing industries and presents empirical results based on the data for 16 Standard Industrial Classification (SIC) three-digit industries from 1959 to 1976. Performances of estimated equations are evaluated by sample-period simulation tests. The estimated coefficients are then used to forecast electricity demand by industry. Results show that most of the estimated coefficients have expected signs and are statistically significant. The estimated equations perform well in terms of sample-period simulation tests, registering small mean absolute percentage errors and mean square percentage errors for most of the industries studied. Forecasted results indicate that total electricity demand by manufacturing industries would grow at an average annual rate of 3.53% according to the baseline forecast, 2.39% in the high-price scenario, and 4.76% in the low-price scenario. The forecasted growth rates vary substantially among industries. The results also indicate that the price of electricity would continue to grow at a faster rate than the general price level in the forecasted period 1977 to 1990. 19 references, 6 tables.

The experimental implementation and comparison of active, semiactive, and passive vehicle suspensions utilizing a linear electric motor
The primary objective of this research is the investigation of the experimental implementation of an active automobile suspension, three types of semiactive suspensions, and a passive suspension. These suspensions are realized via computer control of a linear electric motor. The details of the suspensions are explained in full assuming no prior knowledge by the reader. A theoretical quarter car model is developed and used to provide baseline performance criteria. Details of the design and development of the experimental test rig are given. The experimental results are compared to the theoretical results to study the effectiveness of the motor at realizing the control strategies. This gives an indication of the feasibility of electric motors for implementation of active and semiactive suspension control strategies. Furthermore, the control algorithms are compared to each other to rate each for performance versus complexity. Also, the experimental results are compared to previous experimental results for a resistance controlled semiactive suspension using dual dampers. The experimental test rig and theoretical simulation results agreed fairly well for all suspension performance criteria. The relative comparisons of each suspension when implemented on the test rig were almost identical to the rankings resulting from theory. The performance criteria showed that an active suspension is substantially better than a passive one. Also, only minimal differences exist between the active suspension and the three semiactive suspensions. This indicates that an active suspension is not needed for excellent suspension performance.

The changing structure of the electric power industry: Selected issues, 1998
More than 3,000 electric utilities in the United States provide electricity to sustain the Nation`s economic growth and promote the well-being of its inhabitants. At the end of 1996, the net generating capability of the electric power industry stood at more than 776,000 megawatts. Sales to ultimate consumers in 1996 exceeded 3.1 trillion kilowatthours at a total cost of more than $210 billion. In addition, the industry added over 9 million new customers during the period from 1990 through 1996. The above statistics provide an indication of the size of the electric power industry. Propelled by events of the recent past, the industry is currently in the midst of changing from a vertically integrated and regulated monopoly to a functionally unbundled industry with a competitive market for power generation. Advances in power generation technology, perceived inefficiencies in the industry, large variations in regional electricity prices, and the trend to competitive markets in other regulated industries have all contributed to the transition. Industry changes brought on by this movement are ongoing, and the industry will remain in a transitional state for the next few years or more. During the transition, many issues are being examined, evaluated, and debated. This report focuses on three of them: how wholesale and retail prices have changed since 1990; the power and ability of independent system operators (ISOs) to provide transmission services on a nondiscriminatory basis; and how issues that affect consumer choice, including stranded costs and the determination of retail prices, may be handled either by the US Congress or by State legislatures.

The Gas/Electric Partnership
The electric and gas industries are each in the process of restructuring and "converging" toward one mission: providing energy. Use of natural gas in generating electric power and use of electricity in transporting natural gas will increase as this occurs. Through an Electric Power Research Institute initiative, an inter-industry organization, the Gas/Electric Partnership, has formed between the electric utilities and gas pipelines. The initial focus of this partnership is to explore issues of culture, technology, and economics in using electric motor driven compressors for moving gas to market.

Further Findings Concerning Electrical Energy Monitoring in an Industrial Plant
The Energy Systems Laboratory (ESL) at Texas A&M University has monitored the real-time electrical energy consumption, demand, and power factor of a large metal fabrication plant in Houston, Texas for twelve months. Monthly reports that present the data in a format that plant personnel find useful are discussed. These reports allow plant personnel to see how power factor correction in conjunction with production retrofits have reduced utility bills despite production capacity increases. The reports have also been useful in detecting maintenance problems and monitoring productivity. A method that allows the calculation of power factor correction savings after correction is discussed. This method requires some power factor versus demand history prior to correction, and is used to determine what the demand would have been if the correction equipment had not been installed, even if the real demand of the plant changes. Major plant electrical modifications and their impact on a monitoring system are also discussed. Such modifications increase the potential for technical problems with the monitoring equipment and result in hard-to-find problems. A future step to be examined is one that uses visual or audible warning devices in the plant to control demand. At least one plant has adopted this idea in the form of warning lights that inform employees to shut down unnecessary equipment. This concept appears to be potentially beneficial to all plants which have some type of demand monitoring device on-site.

Assessing strategies to address transition costs in a restructuring electricity industry
Restructuring the US electricity industry has become the nation`s central energy issue for the 1990s. Restructuring proposals at the federal and state levels focus on more competitive market structures for generation and the integration of transmission within those structures. The proposed move to more competitive generation markets will expose utility costs that are above those experienced by alternative suppliers. Debate about these above-market, or transition, costs (e.g., their size,who will pay for them and how) has played a prominent role in restructuring proceedings. This paper presents results from a project to systematically assess strategies to address transition costs exposed by restructuring the electricity industry.

Office New Work With Motor Systems The Energy Analyis Program has recently started a project for the DOE Office of Industrial Technologies Motor Challenge Program. This project, to be carried out in the Washington D.C. office, extends the office's work to an exciting new area of electric motor system efficiency. Motor systems consume about 70 percent of the electric energy used in the U.S. industrial sector. Emphasis on motor efficiency in recent years has led to passage of efficiency standards, to become effective in 1997, for most common types of motors. This is extremely important because the cost of energy consumed by a motor during its useful life typically far exceeds its acquisition cost. Frequently, significant system-level opportunities

Electric Utilities' Role in Industrial Competitiveness: Going Beyond the Energy Audit
This paper describes EPRI's Partnership for Industrial Competitiveness. The Partnership, comprised of over 15 EPRI member utllities, was established to help electric utilities identify, develop; and implement competitiveness improvement opportunities for their industrial customers. To be meaningful, strategies for increasing industrial competitiveness must consider not only energy use, but also all other production inputs. To this end, the program focusses on three major areas: productivity, environmental protection, and efficiency. The effectiveness of the program will be gauged by its ability to keep utility customers "alive and well."

Cost Effective, High Efficiency Integrated Systems Approach to Auxilliary Electric Motors
The CARAT program, carried out by Kinetic Art & Technology Corporation (KAT), has been one of the most commercially successful KAT R&D programs to date. Based on previous development of its technology, KAT designed, constructed and tested a highly efficient motor and controller system under this CARAT program with supplemental commercial funding. Throughout this CARAT effort, the technical objectives have been refined and refocused. Some objectives have been greatly expanded, while others have been minimized. The determining factor in all decisions to refocus the objectives was the commercial need, primarily the needs of KAT manufacturing partners. Several companies are employing the resulting CARAT motor and controller designs in prototypes for commercial products. Two of these companies have committed to providing cost share in order to facilitate the development. One of these companies is a major manufacturing company developing a revolutionary new family of products requiring the ultra-high system efficiency achievable by the KAT motor and controller technologies (known as Segmented ElectroMagnetic Array, or SEMA technology). Another company requires the high efficiency, quiet operation, and control characteristics afforded by the same basic motor and controller for an advanced air filtration product. The combined annual production requirement projected by these two companies exceeds one million units by 2005.

Electric power industry restructuring in Australia: Lessons from down-under. Occasional paper No. 20
Australia`s electric power industry (EPI) is undergoing major restructuring. This restructuring includes commercialization of state-owned electric organization through privatization and through corporatization into separate governmental business units; structural unbundling of generation, transmission, retailing, and distribution; and creation of a National Electricity Market (NEM) organized as a centralized, market-based trading pool for buying and selling electricity. The principal rationales for change in the EPI were the related needs of enhancing international competitiveness, improving productivity, and lowering electric rates. Reducing public debt through privatization also played an important role. Reforms in the EPI are part of the overall economic reform package that is being implemented in Australia. Enhancing efficiency in the economy through competition is a key objective of the reforms. As the need for reform was being discussed in the early 1990s, Australia`s previous prime minister, Paul Keating, observed that {open_quotes}the engine which drives efficiency is free and open competition.{close_quotes} The optimism about the economic benefits of the full package of reforms across the different sectors of the economy, including the electricity industry, is reflected in estimated benefits of a 5.5 percent annual increase in real gross domestic product and the creation of 30,000 more jobs. The largest source of the benefits (estimated at 25 percent of total benefits) was projected to come from reform of the electricity and gas sectors.

This chapter addresses past, ongoing, and short (to 2010) and medium-term (to 2030) future actions that can be taken to mitigate GHG emissions from the manufacturing and process industries. Globally, and in most countries, CO{sub 2} accounts for more than 90% of CO{sub 2}-eq GHG emissions from the industrial sector (Price et al., 2006; US EPA, 2006b). These CO{sub 2} emissions arise from three sources: (1) the use of fossil fuels for energy, either directly by industry for heat and power generation or indirectly in the generation of purchased electricity and steam; (2) non-energy uses of fossil fuels in chemical processing and metal smelting; and (3) non-fossil fuel sources, for example cement and lime manufacture. Industrial processes also emit other GHGs, e.g.: (1) Nitrous oxide (N{sub 2}O) is emitted as a byproduct of adipic acid, nitric acid and caprolactam production; (2) HFC-23 is emitted as a byproduct of HCFC-22 production, a refrigerant, and also used in fluoroplastics manufacture; (3) Perfluorocarbons (PFCs) are emitted as byproducts of aluminium smelting and in semiconductor manufacture; (4) Sulphur hexafluoride (SF{sub 6}) is emitted in the manufacture, use and, decommissioning of gas insulated electrical switchgear, during the production of flat screen panels and semiconductors, from magnesium die casting and other industrial applications; (5) Methane (CH{sub 4}) is emitted as a byproduct of some chemical processes; and (6) CH{sub 4} and N{sub 2}O can be emitted by food industry waste streams. Many GHG emission mitigation options have been developed for the industrial sector. They fall into three categories: operating procedures, sector-wide technologies and process-specific technologies. A sampling of these options is discussed in Sections 7.2-7.4. The short- and medium-term potential for and cost of all classes of options are discussed in Section 7.5, barriers to the application of these options are addressed in Section 7.6 and the implication of industrial mitigation for sustainable development is discussed in Section 7.7. Section 7.8 discusses the sector's vulnerability to climate change and options for adaptation. A number of policies have been designed either to encourage voluntary GHG emission reductions from the industrial sector or to mandate such reductions. Section 7.9 describes these policies and the experience gained to date. Co-benefits of reducing GHG emissions from the industrial sector are discussed in Section 7.10. Development of new technology is key to the cost-effective control of industrial GHG emissions. Section 7.11 discusses research, development, deployment and diffusion in the industrial sector and Section 7.12, the long-term (post-2030) technologies for GHG emissions reduction from the industrial sector. Section 7.13 summarizes gaps in knowledge.

The Use of Electricity in Industry and Energy Saving - The Gamma Co-Efficient
Use of electricity in manufacturing processes is not only limited to its specific utilizations as motion power, lighting, electrolysis. Worldwide energy troubles involve in France a great voluntee to substitute in industrial processes the nuclear electricity to the oil-burning one. The main part of these uses the replacement thermal ones. Of course, electrical processes which will develop are technically tested and economically justified. Energetic comparison of concurrent processes leads to the use of simple factors : the gamma factor. It is, when using energy, the number of thermies which are replaced by one kWh. Gamma is not a factor for measuring the oil saving but the using efficiency. For measuring the oil saving, the author uses 'the net gain of oil weight'. Examples of applications and main results are given in various industrial branches.

An Industrial Control System for the Supervision of the CERN Electrical Distribution Network
CERN operates a large distribution network for the supply of electricity to the particle accelerators, experiments and the associated infrastructure. The distribution network operates on voltage levels from 400 V to 400 kV with a total yearly consumption of near to 1000 GWh. In the past, the laboratory has developed an in-house control system for this network, using the technologies applied to the accelerator control system. However, CERN is now working on a project to purchase, configure and install an industrial Electrical Network Supervisor (ENS). This is a state-of-the-art industrial control system completely developed and supported by an external contractor. The system - based on a scalable and distributed architecture - will allow the installation to be performed gradually, and will be tested while the existing system is fully operational. Ultimately, the complete electrical distribution network will be supervised with this new system, the maintenance and further development of which will be the complet...

Electricity matters: A new incentives approach for a changing electric industry
The method of regulating a utility`s rates should be changed fundamentally to promote responses to competition. An approach that addresses price caps, profit sharing and affords flexibility in pricing can offer utilities and those they serve a {open_quotes}win-win{close_quotes} scenario. U.S. businesses face fiercely difficult challenges to compete in the global marketplace, requiring many firms to search for new and innovative competitive strategies. American business must make fundamental changes to cope with the forces of competition - or risk going out of business. Electricity suppliers can facilitate economic progress by providing cost-effective, high-quality and reliable service to their customers. But as many utility managers know too well, this goal is not easy to achieve. For regulators, it is important to frame and resolve the issues in a proactive way. At the outset, American electric utilities must have strong incentives to be efficient. The purpose of this paper is to explore some of the incentive regulation techniques, such as price-cap regulation, which U.S. and foreign electric utilities should use to facilitate change. These techniques can better accomodate the current mixed competitive and regulated environment while providing an appropriate transition to a dynamically competitive electric services market.

Impacts of Electric Industry Restructuring on Electric Generation and Fuel Markets: Analytical and Business Challenges
Restructuring and increasing competition are likely to have a major impact on electric generating companies and the individuals and organizations that buy, transport, market, or supply fuels. Restructuring may also affect the patterns of coal and gas use. This report, the first in a series by EPRI and the Gas Research Institute (GRI), describes the scope of these potential impacts.
'Tilted' Industrial Electric Rates: A New Negative Variable for Energy Engineers
The cost of purchased electricity for industry is rising even faster than for other sectors. Conventional means of reducing power costs include internal techniques like load management, demand controls and energy conservation. External mechanisms such as contract negotiations with the serving utility can also help keep unit costs of purchased power down. But regulatory policy by agencies governing the serving utility can also have a major impact on electric rate design, by imposing rate structures that require the industrial user to pay above-cost power prices. New trends in electricity ratemaking depart so radically from traditional cost-of-service standards that power-intensive manufacturers could soon end up paying up to 25% more for their electricity than it actually costs to generate and deliver it. Political pressure to mitigate the impact of high energy prices on residential customers led to enactment of the Public Utility Regulatory Policies Act of 1978 (PURPA), requiring every state to consider implementing alternatives to traditional cost-of-service ratemaking techniques. Increasingly, state legislation is also being introduced to achieve similar goals. The stakes for a manufacturing company can be great. If a company is small or unstable, or otherwise unable to absorb or pass on above cost energy prices, it may go out of business. Alternately, it may increase the price of its product in order to recover the new cost of electricity, plus all the administrative costs of handling what is in effect a straight cost pass-through. Traditionally, energy engineers have managed costs by securing favorable power contracts, and by using electricity efficiently. Increasingly, however, they will have to become involved in the public policy debate on electricity rate making in order to help assure that industry has equitable rates in the future.

Region-specific study of the electric utility industry. Phases I and II. Executive summary
This report describes the problems either confronting or likely to confront the electric utility industry in the event of a return of high rates of inflation. It attempts to assess the future of this industry and makes recommendations to resolve fundamental problems. The Virginia-Carolinas subregion (VACAR) of the Southeastern Electric Reliability Council (SERC) was selected for this regional study because of the willingness of a wide range of parties to participate and its representative mix of powerplants, for example coal, hydro, nuclear and oil. It was found that the future supply of reliable, economic electricity is in jeopardy because of the regulatory process, the increasing risk associated with large scale generating stations and the weakening of the nuclear option. A number of options for the future were considered, including deregulation, government ownership and retaining the present system with modifications. The option selected to improve the condition of the electricity industry was to make the present system work. The present system is sound and, with modifications, problems could be solved within the existing framework. A series of recommendations, developed through a consensus building effort involving state government officials, state regulators and investor-owned utility representatives, are presented. A discussion of the need for innovative solutions and one state's approach to the problem concludes the report.

U.S. and Chinese experts perspectives on IGCC technology for Chinese electric power industry
Although China is a very large and populous nation, and has one of the longest known histories in the world, it has only lately begun to seek its place among modern industrial nations. This move, precipitated by the government`s relatively recently adopted strategic goals of economic development, societal reform and promotion of engagement with other industrial nations, has brought to the fore the serious situation in which the Chinese electric power industry finds itself. Owing to the advanced average age of generation facilities and the technology used in them, serious expansion and modernization of this industry needs to take place, and soon, if it is to support the rapid industrial development already taking place in China. While China does have some oil and gas, coal constitutes its largest indigenous energy supply, by far. Coal has been mined and utilized for years in China. It is used directly to provide heat for homes, businesses and in industrial applications, and used to raise steam for the generation of electricity. The presently dominant coal utilization methods are characterized by low or marginal efficiencies and an almost universal lack of pollution control equipment. Because there is so much of it, coal is destined to be China`s predominant source of thermal energy for decades to come. Realizing these things--the rapidly increasing demand for more electric power than China presently can produce, the need to raise coal utilization efficiencies, and the corresponding need to preserve the environment--the Chinese government moved to commission several official working organizations to tackle these problems.

Maintaining Generation Adequacy in a Restructuring U.S. Electricity Industry
Historically, decisions on the amounts, locations, types, and timing of investments in new generation have been made by vertically integrated utilities with approval from state public utility commissions. As the U.S. electricity industry is restructured, these decisions are being fragmented and dispersed among a variety of organizations. As generation is deregulated and becomes increasingly competitive, decisions on whether to build new generators and to retire, maintain, or repower existing units will increasingly be made by unregulated for-profit corporations. These decisions will be based largely on investor assessments of future profitability and only secondarily on regional reliability requirements. In addition, some customers will choose to face real-time (spot) prices and will respond to the occasionally very high prices by reducing electricity use at those times. Market-determined generation levels will, relative to centrally mandated reserve margins, lead to: (1) more volatile energy prices; (2) lower electricity costs and prices; and (3) a generation mix with more baseload, and less peaking, capacity. During the transition from a vertically integrated, regulated industry to a deintegrated, competitive industry, government regulators and system operators may continue to impose minimum-installed-capacity requirements on load-serving entities. As the industry gains experience with customer responses to real-time pricing and with operation of competitive intrahour energy markets, these requirements will likely disappear. We quantitatively analyzed these issues with the Oak Ridge Competitive Electricity Dispatch model (ORCED). Model results show that the optimal reserve margin depends on various factors, including fuel prices, initial mix of generation capacity, and customer response to electricity prices (load shapes and system load factor). Because the correct reserve margin depends on these generally unpredictable factors, mandated reserve margins might be too high, leading to higher electricity costs and prices. Absent mandated reserve margins, electricity prices and costs decline with increasing customer response to prices during high-demand periods. The issues discussed here are primarily transitional rather than enduring. However, the transition from a highly regulated, vertically integrated industry to one dominated by competition is likely to take another five to ten years.

Electrostatic generator/motor having rotors of varying thickness and a central stator electrically connected together into two groups
A sub-module consists of a set of two outer sets of stationary fan-blade-shaped sectors. These outer sectors include conductive material and are maintained at ground potential in several examples. Located midway between them is a set of stationary sector plates with each plate being electrically insulated from the others. An example provides that the inner sector plates are connected together alternately, forming two groups of parallel-connected condensers that are then separately connected, through high charging circuit resistances, to a source of DC potential with respect to ground, with an additional connecting lead being provided for each group to connect their output as an AC output to a load. These same leads can he used, when connected to a driver circuit, to produce motor action.

Different approaches to estimating transition costs in the electric- utility industry
The term ``transition costs`` describes the potential revenue shortfall (or welfare loss) a utility (or other actor) may experience through government-initiated deregulation of electricity generation. The potential for transition costs arises whenever a regulated industry is subject to competitive market forces as a result of explicit government action. Federal and state proposals to deregulate electricity generation sparked a national debate on transition costs in the electric-utility industry. Industry-wide transition cost estimates range from about $20 billion to $500 billion. Such disparate estimates raise important questions on estimation methods for decision makers. This report examines different approaches to estimating transition costs. The study has three objectives. First, we discuss the concept of transition cost. Second, we identify the major cost categories included in transition cost estimates and summarize the current debate on which specific costs are appropriately included in these estimates. Finally, we identify general and specific estimation approaches and assess their strengths and weaknesses. We relied primarily on the evidentiary records established at the Federal Energy Regulatory Commission and the California Public Utilities Commission to identify major cost categories and specific estimation approaches. We also contacted regulatory commission staffs in ten states to ascertain estimation activities in each of these states. We refined a classification framework to describe and assess general estimation options. We subsequently developed and applied criteria to describe and assess specific estimation approaches proposed by federal regulators, state regulators, utilities, independent power companies, and consultants.

Control requirements for cogen and microgen plants in a deregulated electricity industry
The deregulation of the electricity production and distribution industry provides opportunities and concerns to the end-users as well as to the electricity producing companies. The end-user objective is to get a reliable source of electrical energy at the lowest rate possible. On the other hand, the primary objective of the three providing companies--generation, transmission, and local distribution--is to profit while satisfying their customers' needs. These three companies may compete for the same customer, and new competitors may enter the arena. The existing technology of the cogeneration plant and the emergence of the microgenerating plant will be used by all the providers and by the end-users to achieve their objectives. The purpose of this paper is to introduce the concept of operation of the microgenerating plant, to identify the requirements of each interested player, and to introduce control strategies.

Developing a Motor Management Policy at BASF
In early 1998 Thomas R. Theising, BASF Corporate Engineering initiated the formation of a motor management team. The goal of the team was to develop a Motor Management Guideline to better manage the purchase and repair of motors used throughout the company. BASF draws a 240MW electrical power load. Accepting that 70% (industry standards range from 63 to 75% for BASF's businesses) of this load was consumed by rotating equipment and assuming an average cost of$401MWh at 8400 hours of annual operation BASF spends over $56M annually to operate electric motors. A guideline to better manage the purchase and repair of these motors could reduce this operating cost by 3 to 5%, which translates to $1.7M to $2.8M annually. An estimated total cost to BASF for implementation is $200K. The development of a Motor Management Guideline required the cooperative effort of a team of individuals. This team consisted of representatives from several BASF manufacturing locations, Corporate Engineering, Corporate Purchasing and Energy Management. Also, BASF included representatives from Duke Power and from Advanced Energy (AE). Advanced Energy had previously provided motor testing services to the BASF facility in Enka, NC.

Impact of Industrial Electric Rate Structure on Load Management - A Utility Viewpoint
A few years ago our response to an inquiry regarding availability of electric service for a large industrial load was something like: 'Let us put this into our production model to determine whether we will have adequate generating capacity to commit to your needs plus load increases under contract and anticipated residential and commercial load growth. If our studies show that we will have generating capacity available, then we should allow a minimum of two years for design and construction. Of course, you will need to plan to build and maintain your substation.' Today our response would be more like 'How soon can you be ready? Can we build and/or maintain your substation for you? Perhaps we can locate a transformer for you to use until permanent facilities are in place?' What has happened to utilities such as GSU to change our perspective so quickly? The turn around began around New Years of 82 with the realization by industry that the recession which had been developing for some 6 months in retail and construction areas was now affecting basic industry. Later we learned that this recession was the most severe and long lasting in this country since the great depression of the 1930's and that fundamental changes would be required by basic industry if it were to survive. Resulting plant reductions and closings severely impacted utilities heavily dependent on industrial business.

Long-term Contracting in a Deregulated Electricity Industry: Simulation Results from a Hydro Management Model
The deregulation of electricity industry has introduced long-term contracting as a tool for hedging risk and strategy. A vital consideration for market participants is the relationship between behaviour in the spot market, and decisions taken in the contract market. We have developed a reservoir management model which integrates a Cournot spot market model into a Dual Dynamic Programming framework. Simulations using this model show that the market outcomes depend strongly upon the level of contracting undertaken by both competitors. We develop hypotheses for the dynamics involved, and present results from the simulation model reinforcing these. 1.

Electric vehicles
Quiet, clean, and efficient, electric vehicles (EVs) may someday become a practical mode of transportation for the general public. Electric vehicles can provide many advantages for the nation's environment and energy supply because they run on electricity, which can be produced from many sources of energy such as coal, natural gas, uranium, and hydropower. These vehicles offer fuel versatility to the transportation sector, which depends almost solely on oil for its energy needs. Electric vehicles are any mode of transportation operated by a motor that receives electricity from a battery or fuel cell. EVs come in all shapes and sizes and may be used for different tasks. Some EVs are small and simple, such as golf carts and electric wheel chairs. Others are larger and more complex, such as automobile and vans. Some EVs, such as fork lifts, are used in industries. In this fact sheet, we will discuss mostly automobiles and vans. There are also variations on electric vehicles, such as hybrid vehicles and solar-powered vehicles. Hybrid vehicles use electricity as their primary source of energy, however, they also use a backup source of energy, such as gasoline, methanol or ethanol. Solar-powered vehicles are electric vehicles that use photovoltaic cells (cells that convert solar energy to electricity) rather than utility-supplied electricity to recharge the batteries. This paper discusses these concepts.

Process Parameters and Energy Use of Gas and Electric Ovens in Industrial Applications
The study was conducted to evaluate the energy use of natural gas and electric ovens in the production of polymer bearings and components. Tests were conducted to evaluate and compare the performance of natural gas and electric ovens in the process of sintering billets which are made from a broad range of materials such as PTFE and other fluoropolymers, elastomers, themosets, themoplastics and composites. The purpose of this study was to compare the process parameters under similar conditions for industrial applications where electric ovens have predominant use. Tests were performed to obtain the process efficiency and examine cost savings potential in converting electric ovens to natural gas. Preliminary results show that, for the plat studied, cost savings of about $10,000 per oven can be achieved, with a simple payback period of less than two years. The results also show that additional energy savings will be realized if the oven size and exhaust flow are carefully selected. The data obtained from these experiments were used to calculate process efficiency. Design features and environmental issues are discussed.

Using Compressed Air Efficiency Projects to Reduce Peak Industrial Electric Demands: Lessons Learned
"To help customers respond to the wildly fluctuating energy markets in California, Pacific Gas & Electric (PG&E) initiated an emergency electric demand reduction program in October 2000 to cut electric use during peak periods. One component of that wide-ranging program focused on industrial compressed air systems as the target for such electric use reductions. What stands out about the compressed air effort is that customer acceptance of the program was very high (8 out of 10 customer sites implemented at least some of the efficiency projects recommended in the program's air system audits) and overall savings levels were more than 3X the original program goal (550 kW vs. 1730 kW). XENERGY, Inc. designed and carried out the program on behalf of PG&E. Key features of the program included working with compressed air system distributors to identify and qualify good customer leads and post-audit technical assistance to help customer implement recommended projects. This paper reviews the project and outlines some of the lessons learned in completing the project."

Optimal Scheduling of Industrial Combined Heat and Power Plants under Time-sensitive Electricity Prices
Combined heat and power (CHP) plants are widely used in industrial applications. In the aftermath of the recession, many of the associated production processes are under-utilized, which challenges the competitiveness of chemical companies. However, under-utilization can be a chance for tighter interaction with the power grid, which is in transition to the so-called smart grid, if the CHP plant can dynamically react to time-sensitive electricity prices. In this paper, we describe a generalized mode model on a component basis that addresses the operational optimization of industrial CHP plants. The mode formulation tracks the state of each plant component in a detailed manner and can account for different operating modes, e.g. fuel-switching for boilers and supplementary firing for gas turbines, and transitional behavior. Transitional behavior such as warm and cold start-ups, shutdowns and pre-computed start-up trajectories is modeled with modes as well. The feasible region of operation for each component is described based on input-output relationships that are thermodynamically sound, such as the Willans line for steam turbines. Furthermore, we emphasize the use of mathematically efficient logic constraints that allow solving the large-scale models fast. We provide an industrial case study and study the impact of different scenarios for under-utilization. 1

Electric Power Interruption Cost Estimates for Individual Industries, Sectors, and the U.S. Economy
Distributed energy resources (DER) have been promoted as the least-cost approach to meeting steadily increasing energy demand. However, it is unclear whether DER deployment can maintain or improve the electric power supply reliability and quality currently available to consumers. This report address two key factors relating to this question: 1) characteristics of existing power supply reliability, and 2) costs resulting from supply interruptions characteristic of the existing power grid. Interruption cost data collected by the University of Saskatchewan was used in conjunction with data generated by the Census Bureau's Annual Survey of Manufacturers (Census Bureau, 1995), along with industry shares of gross domestic product (Bureau of Economic Analysis, 1995a) and gross output (Bureau of Economic Analysis, 1995b) to derive interruption cost estimates for U.S. industries at the 2-digit Standard Industrial Classification (SIC) level, as well as for broader sectors and the U.S. economy. Interruption cost estimates are presented as a function of outage duration (e.g., 20 minutes, 1-hour, 3-hour), and are normalized in terms of dollars per peak kW.

Apparatus and method for servicing an elongated suspended pump motor in an electric power plant with limited access
Elongated coolant pumps suspended under steam generators within containment in a power plant with limited access space, are removed and replaced by an elongated maintenance cart with an elongated opening along one side in which the motor is received. Rollers support the cart for conveying the elongated motor in an upright position out from under the steam generator and onto an elevator. The elevator is lowered to transfer support of the cart and motor through trunnions to saddles straddling the elevator for rotation of the cart to a generally horizontal position. The elevator then raises the horizontally disposed cart carrying the motor to a higher floor where it is rolled off the elevator and out through the auxiliary equipment hatch. 14 figures.

Changes in the electricity consumption of commercial buildings and industrial facilities (C&I facilities) during Demand Response (DR) events are usually estimated using counterfactual baseline models. Model error makes it difficult to precisely quantify these changes in consumption and understand if C&I facilities exhibit event-to-event variability in their response to DR signals. This paper seeks to understand baseline model error and DR variability in C&I facilities facing dynamic electricity prices. Using a regression-based baseline model, we present a method to compute the error associated with estimates of several DR parameters. We also develop a metric to determine how much observed DR variability results from baseline model error rather than real variability in response. We analyze 38 C&I facilities participating in an automated DR program and find that DR parameter errors are large. Though some facilities exhibit real DR variability, most observed variability results from baseline model error. Therefore, facilities with variable DR parameters may actually respond consistently from event to event. Consequently, in DR programs in which repeatability is valued, individual buildings may be performing better than previously thought. In some cases, however, aggregations of C&I facilities exhibit real DR variability, which could create challenges for power system operation.

Advanced Motors
Project Summary Transportation energy usage is predicted to increase substantially by 2020. Hybrid vehicles and fuel cell powered vehicles are destined to become more prominent as fuel prices rise with the demand. Hybrid and fuel cell vehicle platforms are both dependent on high performance electric motors. Electric motors for transportation duty will require sizeable low-speed torque to accelerate the vehicle. As motor speed increases, the torque requirement decreases which results in a nearly constant power motor output. Interior permanent magnet synchronous motors (IPMSM) are well suited for this duty. , , These rotor geometries are configured in straight lines and semi circular arc shapes. These designs are of limited configurations because of the lack of availability of permanent magnets of any other shapes at present. We propose to fabricate rotors via a novel processing approach where we start with magnet powders and compact them into a net shape rotor in a single step. Using this approach, widely different rotor designs can be implemented for efficiency. The current limitation on magnet shape and thickness will be eliminated. This is accomplished by co-filling magnet and soft iron powders at specified locations in intricate shapes using specially designed dies and automatic powder filling station. The process fundamentals for accomplishing occurred under a previous Applied Technology Program titled, ���������������¢��������������������������������Motors and Generators for the 21st Century���������������¢�������������������������������. New efficient motor designs that are not currently possible (or cost prohibitive) can be accomplished by this approach. Such an approach to motor fabrication opens up a new dimension in motor design. Feasibility Results We were able to optimize a IPMSM rotor to take advantage of the powder co-filling and DMC compaction processing methods. The minimum low speed torque requirement of 5 N-m can be met through an optimized design with magnet material having a Br capability of 0.2 T. This level of magnetic performance can be met with a variety of bonded magnet compositions. The torque ripple was found to drop significantly by using thinner magnet segments. The powder co-filling and subsequent compaction processing allow for thinner magnet structures to be formed. Torque ripple can be further reduced by using skewing and pole shaping techniques. The techniques can be incorporated into the rotor during the powder co-filling process.

Solar Thermal Small Power Systems Study. Inventory of US industrial small electric power generating systems. [Less than 10 MW
This inventory of small industrial electric generating systems was assembled by The Aerospace Corporation to provide a data base for analyses being conducted to estimate the potential for displacement of these fossil-fueled systems by solar thermal electric systems no larger than 10 MW in rated capacity. The approximately 2100 megawatts generating capacity of systems in this category constitutes a potential market for small solar thermal and other solar electric power systems. The sources of data for this inventory were the (former) Federal Power Commission (FPC) Form 4 Industrial Ledger and Form 12-C Ledger for 1976. Table 1 alphabetically lists generating systems located at industrial plants and at Federal government installations in each of the 50 states. These systems are differentiated by type of power plant: steam turbine, diesel generator, or gas turbine. Each listing is designated as a power system rather than a power unit because the FPC Ledgers do not provide a means of determining whether more than one unit is associated with each industrial installation. Hence, the user should consider each listing to be a system capacity rating wherein the system may consist of one or more generating units with less than 10 MW/sub e/ combined rating. (WHK)

Motor current signature analysis method for diagnosing motor operated devices
A motor current noise signature analysis method and apparatus for remotely monitoring the operating characteristics of an electric motor-operated device such as a motor-operated valve. Frequency domain signal analysis techniques are applied to a conditioned motor current signal to distinctly identify various operating parameters of the motor driven device from the motor current signature. The signature may be recorded and compared with subsequent signatures to detect operating abnormalities and degradation of the device. This diagnostic method does not require special equipment to be installed on the motor-operated device, and the current sensing may be performed at remote control locations, e.g., where the motor-operated devices are used in accessible or hostile environments.
