The recent September/October issue of IEEE Power and Energy magazine focused on synchrophasor technology – the use of real-time phasor measurements synchronized to an absolute time reference to provide instantaneous and accurate information on the condition of the electric system. Several articles in the issue feature projects that involve the RTDS Simulator. RTDS Technologies’ participation in synchrophasor-related industry working groups, along with our continuing focus on phasor measurement units (PMUs) as part of our R&D program, ensures that the RTDS Simulator’s facilities for PMU simulation and testing are at the cutting edge. We are proud to see our customers’ work with the Simulator as a recurring topic in IEEE Power and Energy articles.
“Challenging Changing Landscapes” (pg. 18) discusses the implementation of synchrophasor technology in the electrical grid of the west coast of the United States to improve grid reliability, performance, and security. The article highlights the work of the Western Electricity Coordinating Council (WECC) to facilitate industry-wide coordination in grid planning and operation. Pacific Gas and Electric Co. (PG&E) uses the RTDS Simulator in their world-class Synchrophasor Proof of Concept Facility in San Ramon, California, where is provides an environment for testing PMU components, interoperability, and applications. It is described as an invaluable test facility for large-scale synchrophasor development, and has placed PG&E among those at the forefront of synchrophasor research in the United States.
“Strategies for Success with Synchrophasors” (pg. 29) brings the reader over to the east cost of the United States, where various system operators, transmission owners, electric utilities, and other grid stakeholders are leading the way in synchrophasor development and integration. Dominion Virginia Power’s real-time digital simulator laboratory, which is used for operator training, is featured in the article. The lab is used to simulate the behavior of the grid in real time and stream PMU measurements from the simulated grid to a software phasor data concentrator (PDC). Engineers and operators can then visualize the effects of simulated events in real time. Dominion has created a comprehensive model of its transmission network on the RTDS Simulator so that trainees can experience realistic contingencies.
“Advancing China’s Smart Grid” (pg. 60) discusses the implementation of PMUs in a Wide-Area Measurement System (WAMS) in China. China Southern Grid (CSG) used the RTDS Simulator to carefully test the Wide-Area Damping Control (WADC) system that was commissioned in 2008. This project saw the installation of six PMUs across three provinces over a distance of over 1,000 km, as well as three HVDC links with a total capacity of over 11 GW. CSG’s controllers were intended to damp certain oscillation modes that were limiting long-distance power transfer. Using the RTDS Simulator, CSG was able to observe the operation of the controllers over a variety of contingency scenarios in a safe, controlled environment.
