摘　　要：提出了一种利用行波法对牵引网故障测距的应用方案。依据AT牵引网实际电路,在ATP软件中建立投切并联电容补偿器模型,对机车在牵引网运行时的电流进行仿真分析,得到发生短路时的故障数据,再利用MATLAB软件对故障数据进行行波法测距,经实验验证,可知行波法对牵引网故障测距行之有效。This paper presented a kind of application scheme making use of the travelling wave method to locate faults for the traction network. Based on the actual circuit of the AT traction network, this paper established the model of a switching parallel capacitance compensator in the software ATP to simulate and analyze the currents when the locomotive was running. The short-circuit fault data was obtained and the software MATLAB was used to carry out fault location by the travelling wave method. The experimental verification show that the travelling wave traction network fault location is effective.
