【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。更多还原

【Abstract】 This paper clarifies the basic principle of Device Dependent Sub-sy nchronous Oscillation (SSO),and a model of synchronous generators that takes the saturation of main magnetic circuit into account is presented.Using the time do main simulation by Saber,the operating mode based on the simple generator-infin ite power system during a three-phase fault is calculated,and some valuable con clusions are obtained.更多还原
