本文采用节点导纳矩阵表示的故障诊断方程,给出了线性有源网络节点故障定位算法,该方法避免了不必要的运算。整个节点故障定位过程中只需讨论双图公共生成树是否存在,并对此问题提出了新的判断方法,当算法不能对故障唯一定位时,仍有可能给出故障区域。该算法用FORTRAN语言编制成程序在IBM-PC微型机上进行了验证。
In this paper, the fault diagnosis equation represented by node admittance matrix is used to solve the fault location algorithm of linear active network. This method avoids unnecessary operations. The entire node fault localization process only needs to discuss the existence of double-figure public spanning tree, and puts forward a new judgment method for this problem. When the algorithm can not uniquely locate the fault, it is still possible to give a fault area. The algorithm was compiled in FORTRAN program and verified on IBM-PC microcomputer.
