摘要
提出了一种使用两端电流、一端电压的高压输电线路故障测距算法。该算法从原理上克服了对端系统助增电流和过渡电阻对故障测距的影响，并对高压长线的电容充电电流进行了迭代补偿；ＥＭＴＰ仿真结果表明，算法有较高的精度。
The paper presents a new fault location algorithm,it uses two-terminal current andone-terminal voltage.The algorithm has eliminated the influence of infeed current and transitionresistance on fault location. The capacitive current of high voltage long line is compensated.Theresult of EMTP simulation shows that the algorithm is precise.
