摘　　要：针对已有的配电网故障定位矩阵算法存在的问题,提出了一种故障定位的优化矩阵算法。该算法针对配电网的结构特点,以联络开关为分界点,根据故障发生时流经FTU监测点的故障过流信息,仅选择包含故障信息的区域参与计算。该算法能对配电网不同运行方式下的单一故障、多重故障进行快速、准确地定位,并且算法中涉及的矩阵均可采用十字链表存储,既降低了算法的空间复杂度,又缩短了算法的运算时间。In allusion to problems existing in current matrix algorithms for fault location in distribution networks, an optimized matrix algorithm for fault location was presented. In view of distribution network’s structural characteristics, this algorithm divided the distribution network into independent sections by opening interconnection switches firstly. Then, according to the fault over-current information flowing through FTU monitoring points while a fault was happening, it only selected the sections that included fault information to compute. The suggested algorithm can diagnose single fault or multiple faults for distribution network in different operating mode. The matrixes used in this algorithm can adopt the orthogonal linked list to store, which not only reduces the space complexity of algorithm, but also cuts down it’s time complexity.
