Eastern Interconnection. The project includes a historian for data archival. The files produced by the historian can later be analyzed using Hadoop. The historian is also designed to be used in distributed systems, having a single node dedicated to archival and several others sending concentrated measurements to the central archive. This design even allows for its use in any distributed system enabling one PDC to filter measurements to another that is running a resource intensive adapter. The local historian provides web services which can be used to monitor the data being archived in real-time. The data quality monitoring adapters provide information about measurements entering the concentrator that have flat-lined, gone out of a specified range, or entered the concentrator with a bad timestamp. Applications Applications included in the openPDC project: The openPDC Console is an application that can be used to send and receive messages between the openPDC service and a client machine. The openPDC Manager is a utility intended to allow remote access and simplify adapter configurations in the database. The PMU Connection Tester can be used to view a live stream of data in one of the supported protocols in order to test that the stream is being received. This tool has been used around the globe and can be installed separately from the rest of the suite. The NASPI PMU Registry allows users to register phasor-related devices to one central location to allow access to information about existing devices and their configurations. ConfigCrypter is a utility for encrypting options in the configuration files. ConfigurationEditor provides a simple GUI-based application used to modify the XML configuration files.
