摘 要:在矿山配电网输电线路发生故障时,要快速准确地确定故障点,及时切除故障,降低停电损失。利用电力系统发生故障后产生的行波进行定位的理论,分析了输电线路故障的行波过程,通过提取分析暂态行波中包含的故障信息,准确及时地检测出故障点。通过MATLAB建模仿真,设置不同阻值的接地电阻和故障点,行波测距的结果没有改变,验证了行波测距的准确性。

Abstract: When the faults take place in the mining distribution transmission line, there is a need to quickly and correctly determine fault points and to switch off the fault to reduce power failure losses. This paper proposed the theory using the traveling wave generating after power system faults taking place to carry out location and analyzed the traveling wave process of transmission line faults. Via pick-up and analysis of the fault information contained in transient traveling wave, the fault points could be detected correctly in time. Through Matlab software modeling simulation and setting grounding resistance of different values and fault points, it is found that there is no change for traveling wave distance measurement, which verifies the correctness of traveling wave distance measurement.
         Key words: mining transmission line; transient traveling wave; MATLAB simulation
