摘　　要：本文分别介绍了邻近电压崩溃指标和电压稳定裕度指标两种基于潮流计算结果的静态电压稳定性指标。设计编写了两种静态电压稳定性指标计算程序,并分别以IEEE57节点系统和IEEE118节点系统为例,进行详细的仿真计算。最后对两种电压稳定性指标进行分析和比较,比较结果显示两种静态电压稳定性指标都可以判断系统是否处于稳定状态,并且可以预测系统中的薄弱节点,但是在计算上,电压稳定裕度指标更为简单和方便。Two kinds of the voltage stability indices based on load flow solutions are introduced in the paper. Those two indicators programming is tested in IEEE57 bus test system and IEEEll8 bus test system, with satisfactory results. Finally, compared with two kinds of static voltage stability index, we can conclude that VCPI index is more complicated than another although they can predict the weak nodes of power system and determine whether the system is stable.
