摘　　要：将带整流负载的同步发电机的ｄ、ｑ轴变量分解为低频分量和高频分量，并分别加以处理。转子回路对高频电流的电阻及阻尼绕组对低频分量的作用可以忽略。在ｄ轴与ｑ轴超瞬变电抗值相差不大的条件下，建立了带整流负载的三相同步发电机的等效电路模型，该模型可用于同步发电机整流系统稳态和似稳态过程的分析计算。给出了系统稳态运行时等效同步发电机的相量图及稳态量的计算方法。The d and q axis variables of a rectifier loaded synchhronous generator are resolved into low frequency and high frequency components, which can be treated separately. The resistances of the rotor circuits to high frequency currents and the effects of the damper windings on low frequency components need not be taken into account. An equivalent circuit model of the rectifier loaded 3 phase synchronous generator with d axis subtransient reactance x ″ d equal to q axis subtransient reactance x ″ q is developed for steady state and quasi steady state analysis of the synchronous rectifier load system. The phasor diagram of the equivalent synchronous generator and the method of performance calculations are presented for steady state operation.
