A model-referenced controller for stabilizing large transient swings in power systems

This short paper deals with a control strategy which is considered reasonable for on-line stabilization of the large transient swings that occur in power systems following a major system disturbance. The strategy is compared to other similar strategies both in terms of philosophy and physical application. The example shows the benefit of on-line coordinated application of a dynamic brake and network switching to the transient stability problem when control decisions are implemented using a proper coordinating control strategy.
