摘　　要：配电网的故障定位是配电网自动化系统中的一项高级功能。为此,针对配电网的特点,结合同步相量测量技术对节点电压方程进行了处理,导出了一种新型的故障定位矩阵算法。该算法具有较强的通用性,求解过程简单快捷,故障定位快速,对于部分类型的故障还可以具体解出故障距离。最后结合IEEE13节点系统和IEEE36节点系统,说明了该算法的定位方法并证实了其有效性。Fault location is an advanced function of distribution automation system. In light of the characteristics of distribution network, the node voltage equation is processed in combination with the technique of synchronized phasor measurement, and a new matrix algorithm for fault location is derived. The algorithm is featured by strong universality, simple solving process and rapid fault location, even able to work out specific fault distance for some types of faults. IEEE 13-node and IEEE 36-node systems are used at last to demonstrate the locating method of the algorithm and verify its effectiveness.
