同塔架设平行双回线的跨线故障精确测距算法

本文首次提出了用单端检测参数进行同塔架设平行双回线跨线故障测距计算的一整套算法。尤其是当发生不含同名相跨线接地故障和各种非对称型跨线不接地故障时的测距算法,其测距精度可以不受对端系统阻抗变化、过渡电阻和负荷电流的影响。所有测距算法均经过计算机的数字仿真试验,其结果令人十分满意。

Intercircuit Fault Location Algorithms Using One Terminal Monitor Data

This paper presents a complete set of intercircuit fault location algorithm using only one terminal measures for double circuit line on the same tower- The accuracies of the part algorithms are immune to the impedance variance of remote end, fault resistance and load flow when the fault do not have the same phase, or is not grounded and symmetrical. All the methods have been tested by the digital simulation of computer,the re-sults are very satisfying-
