电力系统PMU最优配置新方法

摘要

According to thecharacters of the Y-matrix and the Interactor Matrix of power system, that the character of the power flow equation can be described by Interactor Matrix is indicated. On the basis, a method of the optimal PMU placement which meets the direct solvable power flow equation is proposed based on the Interactor Matrix. The validity and flexibility of the proposed algorithm is tested by using the typical standard nodes system and the results show that less amount of PMU is needed to realize the direct solvable power flow.%根据电力系统导纳矩阵和节点关联矩阵的特点,指出电力系统潮流方程的特征可用系统关联矩阵来描述,在此基础上提出了一种基于关联矩阵的满足潮流方程直接可解的电力系统PMU最优配置方法,最后利用典型标准节点系统对该算法进行验证并与已有方法得到的结果进行比较,结果表明该算法是有效的,具有简单、易于实现的优点,能有效减少PMU配置数目.
