摘要
研究了将高压输电线中利用故障电流分量消除过渡电阻影响的阻抗测距原理用于单边供电的牵引网馈线故障测距的算法。根据实际可能存在的机车与故障点的相对位置 ,分牵引网上无负荷电流、有负荷电流且牵引网故障点发生在机车与变电所之间、有负荷电流且故障点发生在机车与变电所以外的 3种情况分别进行了仿真 ,仿真结果证明此法用于牵引网故障测距较常规阻抗测距法测距精度将大大提高。
This research introduces a new method, which has been used in high voltage line for eliminating fault impedance and its impact on measure of fault location is studied to apply to traction networks fault location in supply model Firstly, EMTP is used in the case of oncurrent in traction networks Comparing with the range routine impedance of fault location, the result is precision greatly Secondly according to the reality possible location between fault location and locomotive heaving current in traction networks, which the fault location is exist on the railway between substation and locomotive or the fault location happens on the distance before locomotive The results of EMTP prove the fact that this method is the best way to measure the fault location of traction networks
