| 摘 要： | 正规形法揭示了电力系统中动态模式之间的非线性相互作用,可用于分析因模式间非线性相互作用而产生的复杂动态现象和动态行为.分析表明,动态模式间相互作用所产生的组合模式使得振荡频率减小或增大,可能导致超低频振荡或倍频振荡现象,而且其明显程度取决于系统的非线性作用程度.正规形变换系数和正规形变量初值乘积可反映超低频振荡模式或倍...

| Abstract: | Normal form method reveals the nonlinear interactions among dynamic modes in electric power systems,which can be applied to analyze complicated dynamic phenomena and dynamic behavior of nonlinear interactions among dynamic modes.Study shows that the combined mode produced by the interactions among dynamic modes causes the decrease or increase of oscillation frequencies and may produce extra-low or double frequency oscillation phenomena,which depends on the degree of nonlinear interaction.The product of norm... |
