Stability of D.W.R. Synchronous Generator as Affected by Forced Excitation Systems

Abstract

Dynamic s:tabil1ty of a divided winding rotor synchronous generator is determined by co-ordination of regulator parameters obtained by applying D-decomposition technique. Transient stability is evaluatfd by simulating faults 11ke (a) sudden 3-phase short circuit,~b) sustained loss of excitation in either 01' the field windings. Results are compared with the transient simulation made on the same generator equipped with regulators, as described by previous authors.
