Abstract

一种获取交流电力网中源荷的支路圴方电流分量的对称方法，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节点电压相位的线性表达式；再据此建立交流电力网稳态的线性对称模型；接着利用M‑P逆矩阵建立全网节点平移电压和节点电压相位关于全网节点源荷功率的线性对称矩阵表达式；然后根据该线性对称矩阵表达式建立支路均方电流关于全网节点源荷功率的对称代数表达式；最后利用Shapley值定理建立获取源荷的支路均方电流分量的对称代数计算式，从而实现交流电力网中源荷的支路均方电流分量的获取。这种源荷的支路均方电流分量为实现交流电力网安全校正、保障其安全运行提供了一种新的高效准确工具。
