摘　　要：在阐明电力系统次同步振荡基本原理的基础上,建立了考虑主磁路饱和的同步发电机模型。通过saber进行时域仿真,对单机一无穷大系统在三相短路时的工况计算分析,并由此得到一些具有价值的结论。This paper clarifies the basic principle of Device Dependent Sub-synchronous Oscillation （SSO）, and a model of synchronous generators that takes the saturation of main magnetic circuit into account is presented. Using the time domain simulation by Saber, the operating mode based on the simple generator-infinite power system during a three-phase fault is calculated, and some valuable conclusions are obtained.
