Ninety percent of major electric power system disturbances in recent years include some aspects of voltage collapse.
This seminar will highlight the importance of reactive power in supporting system voltage. It will review the relationship of voltage support to angular or dynamic stability, and the impact of low reactive reserves in precipitating or aggravating major disturbances. The seminar will then discuss the specific problems that arose in five major disturbances, one in Quebec 1989, two in the WECC in 1996, the NE USA and Canada blackout in 2003 and the South Sweden blackout in 2003. We will also present a rare demonstration of an actual voltage collapse demonstrating a classic PV curve. This information was captured from a relay event record during a disturbance in Peru in October 2001.
