【摘要】 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.更多还原

【Abstract】 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 including 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.更多还原
