摘　　要：本文针对数字式同步发电机自并励静止整流器励磁控制系统 ,研究了电力系统频率偏移对励磁控制的影响 ,导出了调节励磁电压的误差随频率偏移的变化规律 ,并提出了对励磁调节误差进行校正的方法。通过仿真证明了该研究的正确性和校正方法的有效性。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.
