摘要
本文提出了一种使用高压输电线路两端电气量进行故障测距的新算法。该方法适用于多种信号形式输入，对两端电气量不需要进行坐标变换，且无真、伪根的判别困难，并对高压长线的电容充电电流进行了补偿。EMTP仿真结果表明，算法的原理是正确的，并具有较高的测距精度。
This paper presents a algorthm for estimatingthe fault location on a two terminal system. This methed usesthe fundamental frequency voltages and currents measured atline terminals. The measurements are not required to be synchoronized and have not been changed in axis. The capacitjvecurrent of a high-voltage long line is compensated. The resultsof steady state simulation and that from EMTP simulatonshow that the algorithm is correct and accurate.
