基于解析方法电力系统的Hopf分岔类型

Hopf Bifurcation Type of Power System Based on Analytic Methods

将中心流形理论分别与直接求周期解法和后继函数法相结合,研究电力系统的Hopf分岔类型.以经典的双机三节点模型为例,说明了理论分析结果与数值模拟结果一致,验证了所给方法的有效性.

We investigated the Hopf bifurcation type of power system by the combining the center manifold theory with the direct periodic solution method and the subsequent function method, respectively. The theoreti- cal analysis result is consistent with the numerical simulation result based on the classical two-machine and three-bus model. Example shows that the proposed methods are valid.
