摘要
本文应用分叉理论研究系统临界点的行为,在给出两个引理的基础上,证明了参数大范围变化时系统电压发生失稳分叉的判别定理,从理论上分析了几种典型负荷静特性对电压稳定性的影响,同时也提出了一些新观点。
This paper presents an analysis of the power system voltage stability based on the bifurcation theory.Two basic lemmas are given and a criterion theorem is proved,which are used to determined the bifurcation domain of power system voltage instability following the change of parameters in large region.Moreover,it provides the rigorous theory and simulation analyses for the power system voltage stability affected by the static characteristics of typical loads.Some new viewpoints are also given.
