【Abstract】 As for digital self excited control system for use with synchronous generator, this paper analyses the influence of power system frequency deviation on automatic excitation regulator, derives the rule of voltage error varying while system frequency deviates from normal rating and presents a kind of correcting method. By simulating, it is shown that the study in this paper is proper and correcting method is effective.更多还原
