摘　　要：对具有反电势负载的同步发电机整流系统的静态稳定性进行了研究,建立了系统稳定性分析的电路模型,分析了系统在微扰条件下各量的变化情况,提出了系统稳定的判据条件,并对此进行了合理解释。通过实例分析对影响系统稳定性的参数进行了计算研究,绘制了系统稳定的参数范围曲线,分析解释了各种参数影响系统稳定性的原因,揭示了同步发电机整流系统的稳定性规律。The operational stability of synchronous generator - rectification system is studied. All variables of the system and their correlations are analyzed in detail under mini -disturbance, and the linear differential equation about the DC - side average current is derived. The stability criterion of the rectification system is conducted and reasonably explained. All parameters that influence system＇s stability are calculated and analyzed by the case analysing, and their ranges for a stable rectification system are given. The paper explains why and how the parameters affect system＇ s stability. The operational stability of synchronous generator- rectification system is correctly recognized.
