Spectral Control Method Applied to a Hydro Generator in a Multimachine Power System

摘要

An excitation control method (Spectral) using state feedback is applied to a hydro-turbiue synchronous generator in a multi- machine power system, while an unsymmetrical fault or a threephase symmetrical fault being applied. The simulation results of the study show that the excitation controller performs satisfactorily in a multimachine environment, when operating in conjunction with the conventional regulators of the other system generators. The proposed method for designing implementable robust excitation controllers is relatively simple to apply, as amply verified by the example given and relevant system simulations.
