一种基于FTU的配网故障定位矩阵单元化算法

Algorithm of Making Matrix Unit for Distribution Networks Fault Location Based on FTU

基于配电网的结构特点和FTU上传的信息,生成一个包含节点邻接方式及各节点故障信息的N×4阶故障电流判断矩阵D,然后把故障电流判断矩阵D分解成若干个4×4阶单元方阵.利用搜索思想对每个单元方阵进行搜索,得出故障区域.算例仿真结果证明了该算法的正确、有效和快速性.

The algorithm applies very much to various faults that aim to distribution networks. First, according to structure of distribution networks and information of FTU, the authors create fault electric current judgment N × 4 matrix ineluding the node abutment method and each node of the fault information, then they break down the fault electric current judgment N × 4 matrix D to some 4 × 4 phalanx units. Searching each matrix unit gains the faultdistrict in the searched thought. Two examples of the fault location are given, which locate fault very easily in the algorithm.
