چکیده

This paper presents the application of automatic under voltage load tripping and switching of shunt reactors as counter measures for fault induced delayed voltage recovery (FIDVR). As dynamic behavior of loads has significant impact on simulating FIDVR, proper load modeling is also discussed in this paper. Simulations conducted on actual network show that the proposed load model is effectively able to simulate FIDVR. It also shown that automatic under voltage load shedding and switching of shunt reactors can be used as counter measures for reducing risk of voltage collapse or over voltage conditions that may take place following load tripping caused by FIDVR.
