摘 要：提出了一種利用行波法對牽引網(wǎng)故障測距的應(yīng)用方案。依據(jù)AT牽引網(wǎng)實際電路，在ATP軟件中建立投切并聯(lián)電容補償器模型，對機車在牽引網(wǎng)運行時的電流進行仿真分析，得到發(fā)生短路時的故障數(shù)據(jù)，再利用MATLAB軟件對故障數(shù)據(jù)進行行波法測距，經(jīng)實驗驗證，可知行波法對牽引網(wǎng)故障測距行之有效。

Abstract: 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.
Key words: traction substation; fault location; travelling wave
