摘要
近年来电力系统中的非线性奇异现象引起了电力科技人员的很大兴趣 [1 ] [2 ] [3] 。本文在文献 [4]的基础上把发电机的模型扩展到四阶 ,利用中心流形理论 ,针对多个系统运行参数 ,分析了电力系统低频振荡中的非线性奇异现象 。
The nonlinear singularity phenomenon of power system has greatly intrigued the researchers of power engineering in recent years.one the basis of reference,the hopf bifurcation resulted from low frequency oscillation of power system has been analyzed again by means of center manifold theory and hopf bifurcation theory in this paper.When the generator mode is expanded to four dimensions and some system operating parameters are changed the new conclusion which is different from linearization analysis is obtained again.
