摘要
针对电力系统稳定控制问题，提出了用局部分叉理论来研究电力系统局部失稳机理，并根据给出的简单系统模型进行了分析，找出了系统失稳特征。通过１个算例，说明从平衡点分叉出来的极限环的稳定性及其大小，可以判断系统的稳定性。
Aimed at the stability control of electric power system ,it is submitted analyzing the mechanics of local destabilization on grid by theory of local bifurcation. The characteristic of destabilization is found out on base of given model of simple system. It is also illustrated how to identify the stability of electric power system by the stability and size of limit cycle bifurcating from balance point.
