Booz Allen Hamilton Distinguished Colloquium in Electrical and Computer Engineering
"A Real-Time Digital Simulation Environment for the Analysis of Large High-Voltage AC-DC Power Systems"
Professor Reza Iravani
University of Toronto
Traditionally, applications of the digital real-time simulator in power system studies are limited to performance evaluation of relay/protection systems. In such applications, a small part, e.g., a transmission line, of an interconnected system is simulated in a real-time simulation environment and the simulated signals are communicated to a physical relay/protection platform in an “open-loop” fashion. Recent proliferation of electronically-coupled apparatus in power systems has introduced unconventional and more sophisticated controls that often include custom-tailored and proprietary hardware/software modules which do not lend themselves to digital time-domain simulation. Consequently, the concept of
control hardware-in-the-loop, based on real-time simulation of the system, has emerged as the approach for design, development and testing of the control platforms. In spite of the recent developments in microelectronics and the availability of powerful processors, the cost associated with a real-time simulator platform for representing a realistic-size power system is still excessive and the main impediment for widespread use of simulators.
Reza Iravani received his B.Sc. degree in 1976 (Tehran, Iran) and until 1979 worked as a consultant for the power utility industry. He received his M.Sc. (1981) and Ph.D. (1985) degrees in electrical engineering from the University of Manitoba, Canada. Presently, he is a professor in the Department of Electrical and Computer Engineering at the University of Toronto. His research interests include grid-integration of wind and solar power plants and control/protection of the high-voltage (HV) converters and HVDC grids.
