摘要
After reviewing the basic voltage instability mechanisms, this chapter describes emergency measures that can be used in order to contain voltage instability and prevent a voltage collapse leading to a blackout. A real case of such a voltage collapse in the Hellenic system is presented and analyzed. Emergency measures presented include existing or projected controls acting on bulk power delivery transformer load tap changers, as well as direct load shedding. An actual design and application of a load shedding controller in the Hydro-Quebec system is presented.
