Analysis of Dynamic Characterstics and Parameters of a Salient-Pole Synchronous Generator after Loss-of-Excitation by Finite Element Method

本文用有限元法研究了凸极同步发电机失磁运行下动态磁场的非正弦分布和饱和特性,依此为基础建立了发电机的状态数学模型,求解单机对无穷大电网产生全失磁的动特性。通过本文实现了发电机动态电感参数的有限元分析与失磁动特性的数字仿真的结合。

This paper deals with the time-dependent parameters of a synchronous generator under variable speed and saturation condition by FEM. With these parameters mathematical model is set up in the state space. Digital simulation of dynamic characteristics of a single generator-infininte bus after loss-of-excitation is realized.
