摘要
基于电力系统不对称故障时负序等值电路的特点进行分析计算以确定输电线路不对称故障点 ,原理上与不对称故障的形式无关 ,方法简单、适用性强。以 T形接线的线路为例进行计算机离线仿真计算 ,结果表明该算法测距精度高 。
Based on the characteristic of negative-sequence equivalent electric circuit under the unbalanced faults of power system, the unbalanced fault on transmission line can be located. The theory has no relation with the forms of unbalanced faults. It is easy and of high adaptability. Computer based off-line simulation of the T-connected transmission line indicates that the fault location isaccurate by the proposed method, and it is less influenced by transition resistance and system parameters.
