GE Digital Energy in Markham, Canada is a leading R&D organization which is involved with developing power systems relaying and control equipment. The company has expressed interest in collaborating with Prof. Rama Gokaraju (University of Saskatchewan) and supporting a NSERC Engage grant proposal to develop a wide area based power network transient analysis system. The work would be performed in the Real-Time Power Systems Simulations Laboratory (3C63) at the University of Saskatchewan under Prof. Rama Gokaraju's guidance. The research work would involve developing a synchrophasor methodology for wide area based transient instability prediction and comparing its performance with state-of-the-art schemes already used in the industry, such as rate of change of frequency methods, blinder based methods. The testing would be carried out using a real time digital simulator (RTDS) available at the University of Saskatchewan. Detailed electromagnetic simulation models of the power systems would be developed on the simulator by the graduate students and the power systems behavior during stressed conditions would be studied. The proposed synchrophasor methodology would be developed for faster prediction of instabilities during these conditions. GE Markham has donated two N60 Network Stability and Synchrophasor Measurement System equipment's for the purpose of testing. The results of the testing would be used by GE to improve their N60 relaying product. The results would published as an IEEE paper. The proposed research will provide a unique opportunity to the students to do testing of network instability conditions on actual equipment using realistic power systems operating conditions.
