Abstract :
A generator excitation control scheme is introduced which is capable of providing good and consistent voltage control performance, despite wide variations in the system operating conditions. The control scheme is organised so that it comprises a main forward loop, based on a standard voltage error signal, as in a conventional AVR, supplemented by an auxiliary loop incorporating direct axis voltage and current signals. The former loop serves to provide the voltage regulation requirements while the latter serves to compensate for the influence of generator load current on dynamic behaviour
