摘要
针对配电网故障定位矩阵算法中存在的问题,提出了一种区域判断的矩阵算法,该方法可用于单电源单一故障与多电源多故障的配电网的故障定位。首先对每条路径上的节点进行等级划分,从而构成支路矩阵;再通过支路矩阵与故障信息矩阵的运算得到故障判断矩阵,由故障判断矩阵可得出故障判据,进而判断出故障所在区域。通过对典型的单电源供电网络和多电源供电网络的算例分析,表明该方法不需要规格化处理,支路矩阵构成简单且计算量小,可快速判断故障位置。
In allusion to problems in matrix algorithm for fault location of power distribution network, this paper presents a kind of matrix algorithm for region iudgement which is suitable for fault location of power distribution network with single power single fault and multi-power multiple fault. It firstly carries out hierarchical partition for nodes on every path so as to form branch matrix. Then it obtains the fault judgement matrix by computation of branch matrix and fault information ma- trix, gets fault criterion from the fault judgement matrix, and further judges out region where the fault is. By example anal- ysis on typical single power supply network and multi-power supply network, it proves that this method needs no normaliza- tion processing and the branch matrix is simple with small calculation quantity, which is able to quickly judge out fault posi- tion.
