摘要
针对近年来电力系统低频振荡中出现的非线性奇异现象，阐述了发生这种现象的机理，并在文献１ 的基础上，把发电机的模型扩展到四阶。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，得到了与常规线性化分析不同的新结论，即增幅性振荡的范围将扩展到Ｓ平面的左半平面。
For the nonlinear singularity phenomenon of power system,it is stated the mechanism of phenomenon.On the basis of references 1, the generator model is expanded to four dimensions.On condition that some system operating parameters are changed,the new conclusion which is different from linearization analysis is obtained.The growing oscillation will be expanded to the left of plan S.The stablility range will be reduced because of the subcritical.
