Simulating Transients with a Circuit Breaker |
In this section you
Learn how to create an electrical subsystem
Simulate transients with a circuit breaker
Compare time domain simulation results with different line models
Learn how to discretize a circuit and compare results thus obtained with results from a continuous, variable time step algorithm
One of the main uses of SimPowerSystems™ software is to simulate transients in electrical circuits. This can be done with either mechanical switches (circuit breakers) or switches using power electronic devices.
First open your circuit1 system and delete the current source connected at node B2. Save this new system as circuit2. Before connecting a circuit breaker, you need to modify the schematic diagram of circuit2. You can group several components into a subsystem. This feature is useful to simplify complex schematic diagrams.
Use this feature to transform the source impedance into a subsystem:
Select the two blocks identified as Rs_eq and Z_eq by surrounding them by a box with the left mouse button and use the Edit > Create subsystem menu item. The two blocks now form a new block called Subsystem.
Using the Edit > Mask subsystem menu item, change the icon of that subsystem. In the Icon section of the mask editor, enter the following drawing command:
The icon now reads Equivalent Circuit, as shown in the figure above.
You can double-click the Subsystem block and look at its content.
Insert a circuit breaker into your circuit to simulate a line energization by opening the Elements library of powerlib. Copy the Breaker block into your circuit2 window.
The circuit breaker is a nonlinear element modeled by an ideal switch in series with a resistance. Because of modeling constraints, this resistance cannot be set to zero. However, it can be set to a very small value, say 0.001 Ω, that does not affect the performance of the circuit:
Open the Breaker block dialog box and set its parameters as follows:
Ron | 0.001 Ω |
Initial state | 0 (open) |
Rs | inf |
Cs | 0 |
Switching times | [(1/60)/4] |
Insert the circuit breaker in series with the sending end of the line, then rearrange the circuit as shown in the previous figure.
Open the scope U2 and click the Parameters icon and select the Data history tab. Click the Save data to workspace button and specify a variable name U2 to save the simulation results; then change the Format option for U2 to be Array. Also, clear Limit data points to last to display the entire waveform for long simulation times.
You are now ready to simulate your system.
Open the PI section Line dialog box and make sure the number of sections is set to 1. Open the Simulation > Configuration Parameters dialog box. As you now have a system containing switches, you need a stiff integration algorithm to simulate the circuit. In the Solver pane, select the variable-step stiff integration algorithm ode23tb.
Keep the default parameters (relative tolerance set at 1e-3) and set the stop time to 0.02 seconds. Open the scopes and start the simulation. Look at the waveforms of the sending and receiving end voltages on ScopeU1 and ScopeU2.
Once the simulation is complete, copy the variable U2 into U2_1 by entering the following command in the MATLAB® Command Window.
These two variables now contain the waveform obtained with a single PI section line model.
Open the PI section Line dialog box and change the number of sections from 1 to 10. Start the simulation. Once the simulation is complete, copy the variable U2 into U2_10.
Before modifying your circuit to use a distributed parameter line model, save your system as circuit2_10pi, which you can reuse later.
Delete the PI section line model and replace it with a single-phase Distributed Parameter Line block. Set the number of phases to 1 and use the same R, L, C, and length parameters as for the PI section line (see Circuit to Be Modeled). Save this system as circuit2_dist.
Restart the simulation and save the U2 voltage in the U2_d variable.
You can now compare the three waveforms obtained with the three line models. Each variable U2_1, U2_10, and U2_d is a two-column matrix where the time is in column 1 and the voltage is in column 2. Plot the three waveforms on the same graph by entering the following command.
plot(U2_1(:,1), U2_1(:,2), U2_10(:,1),U2_10(:,2), U2_d(:,1),U2_d(:,2));
These waveforms are shown in the next figure. As expected from the frequency analysis performed during Analyze a Simple Circuit, the single PI model does not respond to frequencies higher than 229 Hz. The 10 PI section model gives a better accuracy, although high-frequency oscillations are introduced by the discretization of the line. You can clearly see in the figure the propagation time delay of 1.03 ms associated with the distributed parameter line.
Receiving End Voltage Obtained with Three Different Line Models
An important product feature is its ability to simulate either with continuous, variable step integration algorithms or with discrete solvers. For small systems, variable time step algorithms are usually faster than fixed step methods, because the number of integration steps is lower. For large systems that contain many states or many nonlinear blocks such as power electronic switches, however, it is advantageous to discretize the electrical system.
When you discretize your system, the precision of the simulation is controlled by the time step. If you use too large a time step, the precision might not be sufficient. The only way to know if it is acceptable is to repeat the simulation with different time steps and find a compromise for the largest acceptable time step. Usually time steps of 20 µs to 50 µs give good results for simulation of switching transients on 50 Hz or 60 Hz power systems or on systems using line-commutated power electronic devices such as diodes and thyristors. You must reduce the time step for systems using forced-commutated power electronic switches. These devices, the insulated-gate bipolar transistor (IGBT), the field-effect transistor (FET), and the gate-turnoff thyristor (GTO) are operating at high switching frequencies.
For example, simulating a pulse-width-modulated (PWM) inverter operating at 8 kHz would require a time step of at most 1 µs.
You now learn how to discretize your system and compare simulation results obtained with continuous and discrete systems. Open the circuit2_10pi system that you saved from a previous simulation. This system contains 24 electrical states and one switch. Open the Powergui, click Configure Parameters, and in the Powergui block parameters dialog box set Simulation type to Discrete. Set the sample time to 25e-6 s. When you restart the simulation, the power system is discretized using a 25 µs sample time.
Open the Simulation > Configuration Parameters dialog box and on the Solver pane set the simulation time to 0.2 s. Start the simulation.
Note Once the system is discretized, there are no more continuous states in the electrical system. So you do not need a variable-step integration method to simulate. In the Simulation > Configuration Parameters > Solver pane, you could have selected the Fixed-step and Discrete (no continuous states) options and specified a fixed step of 25 µs. |
To measure the simulation time, you can restart the simulation by entering the following commands.
tic; sim(gcs); toc
When the simulation is finished the elapsed time in seconds is displayed in the MATLAB Command Window.
To return to the continuous simulation, open the Powergui block parameters dialog box and set Simulation type to Continuous. If you compare the simulation times, you find that the discrete system simulates approximately 3.5 times faster than the continuous system.
To compare the precision of the two methods, perform the following three simulations:
For each simulation, save the voltage U2 in a different variable. Use respectively U2c, U2d25, and U2d50. Plot the U2 waveforms on the same graph by entering the following command.
plot(U2c(:,1), U2c(:,2), U2d25(:,1),U2d25(:,2), U2d50(:,1),U2d50(:,2))
Zoom in on the 4 to 12 ms region of the plot window to compare the differences on the high-frequency transients. The 25 µs compares reasonably well with the continuous simulation. However, increasing the time step to 50 µs produces appreciable errors. The 25 µs time step would therefore be acceptable for this circuit, while obtaining a gain of 3.5 on simulation speed.

"The Shaker movement in America began in 1774 when Mother Ann Lee emigrated from Manchester, England, with a small group of followers, and settled in New York State. Despite impoverished beginnings, the Shakers flourished in the early nineteenth century, and by 1840 there were four to six thousand members living in eighteen principle communities from Maine to Kentucky. Turning away from society, they lived in large families that were both celibate and communal. In striving for heaven on earth, they created a visual environment of such harmony and quiet power that it continues to impress observers today, when the Shakers have all but passed from the American scene. The many works presented in this beautiful volume reveal the Shaker commitment to excellence in all matters. The chairs, cases of drawers, work stands, baskets, oval boxes, wheelbarrows, stoves, looms, and even tailoring tools have a purity of form that transcends mere utility and elevates our appreciation beyond a sense of function."--Amazon.

I got the "Point, You don't"Submitted by Guest3333 (not verified) on Sat, 09/22/2012 - 1:54pm.
TAXATION BY CITATION without representation is at work here. The government could give two flips about your safety. The seatbelt law is a hoax. It only exists to collect citations and court costs. That's why we don't have seatbelts on school busses or motorcycles, and riding in the back of pick-up trucks. Why can't you see the plain truth when it's squarely in your face?! Do you really believe that your county government is in control of rabies? Because they collect taxes for your dog ownership? Well then, rabies should be erradicated by now, but instead, we have a 100% increase this year in New Hanover alone. After the county has collected a million dollars - in TAXES. Pender County had no increase, with a tenth of the same budget. People need to wake up. Your government is taxing you to death with citations. And, buckle up your seatbelt, because they're coming up with new rules and laws to cite you every day. You are a bunch of poor SUCKERS, because you believe government is looking out for your health and welfare. »

I've got the S5 boot logo and sound on my S4, but I've noticed the sound is way out of sync with the logo animation.
Is there any reason as to why this might be happening? It seems to very from boot to boot, but it's never in sync at all.
I'm currently running NC9 De-Odexed with Adam Kernel.
Is there any fix to this? It's not a massive thing, but it is confusing me slightly.

2 Entertain (Firm)
Becoming Jane
by Anne Hathaway
13 editions published between 2007 and 2012 in English and held by 2,043 WorldCat member libraries worldwide The year is 1795 and Jane Austen is a feisty 20-year-old. The emerging writer already sees a world beyond class and commerce, pride and prejudice, and dreams of doing what was then nearly unthinkable--marrying for love. Her parents prefer a wealthy husband, to assure their daughter's future social standing, and are eyeing Mr. Wisley, nephew to the very rich and very formidable Lady Gresham, as a prospective match. But when Jane meets the roguish and decidedly non-aristocratic Tom Lefroy, sharp repartee leads to flying sparks. His intellect and arrogance raise her ire - then knock her head over heels. The couple, whose flirtation flies in the face of the sense and sensibility of the age, is faced with a terrible dilemma. If they attempt to marry, they will risk everything that matters - family, friends and fortune
Brideshead revisited
by Evelyn Waugh
2 editions published between 2008 and 2009 in English and held by 1,262 WorldCat member libraries worldwide When the charming aristocrat Sebastian invites Charles Ryder to his family's estate, Charles becomes seduced by the opulent lifestyle of the Marchmain family, and by Julia, Sebastian's sister. As their romance deepens, repercussions follow, and Charles discovers that at Brideshead, love, money and power come at a price
Simon Schama's Power of art
by Simon Schama
8 editions published between 2006 and 2010 in English and held by 1,245 WorldCat member libraries worldwide Focusing on eight iconic works of art, this series reveals the history of visual imagination through the ages. A combination of reconstruction, photography and storytelling transport the viewer back to the intense moments when great works were conceived and born: the murderous, messianic world of Baroque Rome; opulent, parvenu Amsterdam; paranoid, revolutionary Paris; Victorian England suffocating beneath riches and righteousness; the madhouses and brothels of Provence; the carnage of civil war Spain; 1950s New York, caught between Cold War jitters and Manhattan glitter. In each place, a great artist is backed into a corner, facing a crisis, given a chance to confound his rivals, enemies and critics one more time
by Elizabeth Cleghorn Gaskell
2 editions published between 2008 and 2010 in English and held by 1,194 WorldCat member libraries worldwide Cranford, in 1842, is a market town in northwest England. It is a place governed by etiquette, custom and above all, an intricate network of ladies. It seems that life has always been conducted according to their social rules. For spinsters Deborah Jenkyns, the arbiter of correctness, and Matty, her demurring sister, the town is a hub of intrigue. Handsome new doctor Frank Harrison has arrived from London; a retired Captain and his daughters move in across the street and preparations for Lady Ludlow's garden party are underway. The town has some secrets which are about to be revealed. But news comes that shakes the town, a railway line from Manchester is coming to Cranford
Bleak House
by Charles Dickens
4 editions published between 2006 and 2009 in English and held by 1,021 WorldCat member libraries worldwide Out of an interminable court case spin three young people each searching for their place in the world. Their story moves fast, swirling through an incredible array of characters from passionate young lovers to ruthless lawyers, from an ice-cold aristocratic beauty to a shrewd relentless detective, until the final thrilling climax
Little Dorrit
4 editions published between 2009 and 2010 in English and held by 931 WorldCat member libraries worldwide Amy Dorrit's (Claire Foy) gentle spirit has never been dampened by the confining walls of the Marshalsea Prison she's lived in her whole life. Despite the dark shadow of debtor's prison, Amy lovingly cares for her father William Dorrit (Tom Courtenay), the longest serving inmate. A possibly redemptive light unexpectedly shines in the form of Arthur Clennam (Matthew Macfadyen), who has been left with the intriguing threads of a mystery after his father's death -- threads that will intertwine his family and fate with the Dorrits. Clennam's exhaustive search for answers involves murder, fortunes gained and lost, the upper echelons and lowest dregs of society, and most surprising of all, a tender romance. Adapted by Andrew Davies (Bleak House, Pride and Prejudice), Little Dorrit, based on the book by Charles Dickens, is a sprawling story as timely as it is moving. - Publisher
Life in the undergrowth

"(There is) a growing number of sextortion victims in Hong Kong, Indonesia, Singapore, Philippines, United Kingdom and the United States with potential victims in Australia, Korea and Malaysia," Philippine police chief Alan Purisima said in a statement on Friday.
Interpol's Digital Crime Centre director Sanjay Virmani told INQUIRER.net at the PNP headquarters in Camp Crame that it appeared that "separate groups were working because obviously, it takes low investment to do this".
United Kingdom Ambassador Asif Ahmad said in a press briefing that "sextortion does not respect any nationality… this is a serious and growing problem."
Local and international police officials got together Friday on the invitation of the PNP, which started a crackdown on "sextortion" activities in the country under Operation "Strikeback" on November 2013.
The operation has since netted 58 suspects from Taguig City and the provinces of Laguna, Bulacan and Bicol.
According to Purisima, the Filipinos arrested would be charged over a range of crimes, including engaging in child pornography, extortion and using technologies to commit fraud.
Detective chief inspector Gary Cunningham, from the Scottish police force's major investigation team told reporters that one teenager in Scotland had committed suicide after being extorted.
Cunningham said the boy was 17 when he killed himself.
More than 530 people in Hong Kong, many aged between 20 and 30, have fallen victim to the scam since the beginning of last year, according to Chief Inspector Louis Kwan, from the Chinese territory's police commercial crime bureau.
Kwan said Hong Kong victims had paid up to US$15,000 in desperate attempts to keep the sexually compromising material private.
But, once hooked, the victims sometimes found they could not escape.
Kwan said some victims paid up to three times before going to the police, "when they realised they could no longer afford to continue paying".
However, authorities emphasised the Philippines was not the hub of the global "sextortion" scams, only that the current investigation had focused on the South-East Asian nation.
"These crimes are not limited to any one country and nor are the victims. That's why international cooperation in investigating these crimes is essential," Interpol's Virmani said.
"Sextortion" is a combination of sex and extortion where a suspect blackmails a victim who has been recorded performing sexual acts online, which include posing nude in front of a webcam.
The blackmailer then uses the video or image to extort more sexual favours or money from the victim in exchange for keeping the recording in his possession and not spreading it online.
Other countries involved in the operation against "sextortion" are Hong Kong, Singapore, Scotland, United Kingdom, and Australia. – ANN/Philippine Inquirer/AFP

Deep Domain Announces Launch of Version 3.0 Reporting Software for Healthcare Providers
With Deep Domain Reporting Software Version 3.0, healthcare providers benefit from significant time- and cost-savings with faster, more affordable EHR reporting.
Redmond, WA (PRWEB) July 16, 2013
Deep Domain, Inc., a leading provider of analytic and electronic health record (EHR) reporting software, today announced the release of Deep Domain Reporting Software Version 3.0. The platform upgrade gives healthcare providers an affordable software solution that significantly improves the EHR reporting process by making it possible for any staff member to create and run reports, which results in significant time- and cost-savings. With Deep Domain's personal dashboards, customized reports and super-fast data queries, healthcare providers can get the answers they need in just minutes compared to waiting days or weeks for one report with the typical reporting process.
With more than half of America's doctors currently using electronic health records, it's become increasingly important for providers to ensure they have the right tools they need to work efficiently and effectively. Typically, the only members of staff that are responsible for extracting the EHR data and creating the reports are the report writers and analysts. It's estimated that the average time it takes to create a report is one or two months and each report is estimated to cost $2500 or more due to the time it takes a report writer which uses special-purpose programming language known as SQL to get the data from the EHR and run the necessary report.
Deep Domain provides a low-cost alternative to this expensive and time-consuming process. Deep Domain charges $78 per month for each provider. It generally takes just minutes to create and run a report, which reduced the waiting period by 98%.
According to Rhonda Huff, CEO of Yakima Neighborhood Clinic, "A single report costs over $2,500 and take weeks; we need dozens of reports and can't afford the resources. There have been no sensible solutions until we discovered Deep Domain."
Deep Domain Reporting Software is currently installed at leading hospitals, such as Swedish Hospital (recently acquired by Providence Health & Services) and Evergreen Hospital, and Community Health Centers throughout the US. Deep Domain is currently upgrading all existing customers to V3 and all new customers will have V3 installed automatically.
"With Deep Domain V3, our customers can create and run all the reports they need for just $78 per month per provider. Not only is it an affordable subscription plan, but it's also a tool that can be used by anyone; meaning that you don't have to be a report writer or analyst to use Deep Domain. We've designed a product that is extremely user-friendly so doctors and administrators can get the information they need…quickly," states Deep Domain's CEO Howard Mahran.
About Deep Domain
Headquartered in Redmond, WA, Deep Domain is an innovative healthcare information company that provides healthcare organizations of all sizes with a cost-effective software solution that automates EHR clinical, financial and quality reporting. Deep Domain's reporting software reduces costs, enhances work efficiencies, and fosters better patient outcomes.

US Marine General John Allen to retire; won't lead US, NATO in Europe
- From: AP
- February 20, 2013
US President Barack Obama said that General John Allen will retire instead of accepting the top job at NATO, as he seeks to take care of his family after a 19-month tour in Afghanistan.
Speculation had been rife for weeks that General Allen, who led the war effort in Afghanistan for 19 months, would not take up Mr Obama's offer to serve as the alliance's supreme commander, even after he was cleared of wrongdoing in a drama over emails to a Florida socialite.
"Today, I met with General John Allen and accepted his request to retire from the military so that he can address health issues within his family," Mr Obama said in a written statement.
General Allen recently returned from his post as the top commander of US and NATO troops in Afghanistan and had asked for more time to think over his future.
Mr Obama praised the Marine Corps general for presiding over "significant growth" in Afghanistan's security forces and a "further degradation" of al-Qaida.
"Above all, he cares deeply for the men and women in uniform who serve our nation - as well as their families - and I am grateful for the sacrifices made by his family in supporting him during his service," Mr Obama said.
General Allen told the Washington Post in an interview published Tuesday that he wanted to focus on helping his wife, Kathy, who has chronic health problems that include autoimmune disorder.
"Right now, I've just got to get her well," General Allen said. "It's time to take care of my family."
He said his decision was not related to the episode over his email exchanges with a Florida woman, Jill Kelley. The Pentagon inspector general investigated the correspondence but concluded General Allen had not violated rules on conduct "unbecoming of an officer," including adultery.
The probe stemmed from a scandal that forced former General David Petraeus to resign as CIA director over an extramarital affair. Ms Kelley had complained to the FBI about harassing emails and authorities then uncovered an affair between General Petraeus and his biographer, Paula Broadwell.
During the investigation, authorities also found emails between General Allen and Ms Kelley that were deemed potentially "inappropriate."
During his time in Afghanistan, General Allen presided over a shift from counter-insurgency operations led by large numbers of US troops to efforts to advise and build up the Afghan security forces.

The Best Time To Take Your Supplements
Out of the hundreds of e-mails I get each week, more than half are from people who are interested in knowing which supplements to take or what the best way is to take the supplements they're currently using.
So this article will show you when to take some of the top supplements and how to get the most out of them.
Creatine, glutamine, and protein are 3 of the top supplements for gaining lean muscle and strength.
But what are the best times to take these proven supplements?
Here's what I've found personally works best for me as well as tracking clients progress using these 3 supplements (which, by the way, are about the only 3 I recommend to clients, other than protein/meal replacements, EFA's and a good multi-vitamin).
There's a lot of conflicting research that shows creatine and glutamine may compete directly with one another for cell transport and absorption.
That's because both creatine and glutamine use the same transport method (sodium) to be absorbed by the body, so there's a chance that one will get absorbed more than the other.
Even though there are different theories as to whether this is true or not, here's my thought:
By-pass the entire problem by just splitting up the timing a little bit.
Supplement Consumption Timing
Best taken 1/2 hour or so BEFORE a workout and again RIGHT after a workout.
What I do is take a creatine/juice/protein drink about a half hour before a workout and than another shake right after.
This "bracketing" technique helps set up an anabolic (muscle-building) state for your muscles and helps prevent muscle breakdown from a workout (catabolism).
Other than these 2 opportune times, you can add another creatine serving or two any time throughout the day.
I usually recommend 25 to 30 grams of creatine on a loading phase and 10-20 grams a day on a maintenance phase.
Definitely take glutamine right before bed.
This is where the overwhelming research shows the value of glutamine raising growth hormone levels significantly by taking 5 grams before bed.
Also, another great time is upon waking, when your muscles have been without significant nutrition for up to 6-8 hours.
Another good time for glutamine is about a half hour or hour after working out.
This helps in the recovery/recuperation process from demanding workouts.
So, creatine definitely before and after your workout and glutamine right before bed and right upon waking.
The best times to take ANY protein drink or protein supplements are as follows.
I've listed them in order of importance, so based upon what you can afford, start at the top of the list and work down.
When Should You Take It?
- The most important time is right after a workout. Your muscles are like a sponge and need instant nutrition for muscle recovery and growth.
- Right before bed. You're about to sleep for 6 to 8 hours. That's a long time without protein. Could you imagine going throughout your day (when awake) not eating 6 to 8 hours?
- Right upon waking. Same thing, you've just gone 6 to 8 hours without proper nutrition. Your body needs protein quick.
- Half hour before a workout. This sets up the "anabolic window" before your workout and provides your muscles with adequate nutrition so that the effects of weight training (weight training breaks down muscle-called catabolic) are not as severe.
I hope this article helped shed some light on when to take the 3 most important supplements for gaining mass and strength.

but doesn't you body digest during sleep? i don't think protein needs to be taken before sleeping or upon awakening. plus, won't your body fuel off of fat before it resorts to muscle? and lastly, doesn't it take something like 24 hrs to become catabolic?
