摘要
本文分析了输电线路故障定位的阻抗测距算法，提出了仅利用单侧电流信息的解一阶方程故障测距方法，特别适用于高阻抗接地短路的故障定位。从原理上解决了一类迭代法的跑根问题及相应解二次方程法的伪根问题。仿真计算表明本文方法具有很高的精度。
This paper presents a new algorithm for locating the power transmission line faults.This algorithm is theoretically accurate and only uses one terminal current data,fault impedance and the uncertainty of line parameters do not affect fault location estimation.The accurate results are easily gived by solving the one order fault location equations.The accurate results are easily gived by solving the one order fault location equations.The digital simulation verifies the high accuracy and applicability of the provieded algorithm.
