Abstract

一种交流电力网支路开断型静态安全性检验的线性非对称方法，首先根据交流电力网中节点源荷功率和支路导纳建立节点源荷功率关于节点平移电压和电压相位的线性表达式；再结合参考节点编号建立交流电力网稳态的线性非对称模型；继而利用常规逆矩阵获取无支路开断型非参考节点平移电压和电压相位以及丢参考节点的节点阻抗矩阵；然后根据该节点阻抗矩阵和一条开断支路，利用修正矩阵的常规逆计算公式获取支路开断型非参考节点平移电压增量和电压相位增量；最后根据无支路开断型非参考节点平移电压和电压相位以及支路开断型非参考节点平移电压增量和电压相位增量检验电力网静态安全性，为实现支路轮断式静态安全性检验提供了一种快速准确方法。
