| 摘 要： | 迄今为止,利用单端信息按阻抗原理进行故障定位的所有方法,其精度均无可避免地要受到对端系统阻抗变化的影响。针对平行双回线的构成特点,本文提出了一种平行双回线之一故障时能够准确计算对端系统阻抗的方法,从而可以完全消除对端系统参数变化对测距精度的影响,该算法经过计算机的仿真试验,取得了十分满意的结果。

| Abstract: | So far, the accuracy of the existing methods of fault location based on calculating the impedance at only one terminal of lines is certainly affected by the variation of the system impedance at the remote end. In accordance with parallel lines' special characteristics, this paper presents a method that can calculate the system impedance of the remote end when one of the two lines has fault, so that the effect of its variation can be eliminated completely. This method has been tested by the computer digital simulation, and the results are very satisfactory. |
