摘　　要：运用支路追加法,基于系统网络结构变化,建立了系统内阻抗模与网络参数之间关系的数学模型;在建立节点电压方程的基础上,将节点功率计及到负荷节点的系统内阻抗模中,得出了计及节点功率后系统内阻抗模与支路参数间的变化关系;基于阻抗模分析法分析了网络结构变化对系统负荷节点电压稳定性的影响,IEEE-11节点系统算例的计算结果表明本文提出的方法用于分析电力系统电压稳定性是行之有效的。The mathematical model in relationship between the system equivalent impedance mode and the network parameters was established by adding branch method; and based on changes of network structure. After node voltages equation was estahlished, node power was put into the inner impedance mode of power system, the relationship between the system inner impedance mode and network parameters was obtained. Based on analysis method of impedance module, the impact of changes in the network structure being concerned with the stability of the system load node voltage, was analyzed. The effectiveness of the proposed method in this dissertation is approved through the example of IEEE-11 typical system.
