Coordination of overexcitation limiter, field overcurrent protection and generator control

The overexcitation limit of synchronous generator plays an important role in the voltage stability of power systems. Achieving maximum use of the overexcitation capability requires adequate coordination between generator control and protection. This paper provides an example of coordination between overexcitation limiter (OEL), field overcurrent protection and automatic voltage regulator (AVR) for a synchronous generator. The coordination achieved is then verified by a model simulation using an electromagnetic transient program for practical scenarios of interest. Suggested modifications to the ST1A type exciter model are presented to represent the complete functionality of the OEL function.
