摘 要：提出了一種利用行波法對(duì)牽引網(wǎng)故障測(cè)距的應(yīng)用方案。依據(jù)AT牽引網(wǎng)實(shí)際電路，在ATP軟件中建立投切并聯(lián)電容補(bǔ)償器模型，對(duì)機(jī)車在牽引網(wǎng)運(yùn)行時(shí)的電流進(jìn)行仿真分析，得到發(fā)生短路時(shí)的故障數(shù)據(jù)，再利用MATLAB軟件對(duì)故障數(shù)據(jù)進(jìn)行行波法測(cè)距，經(jīng)實(shí)驗(yàn)驗(yàn)證，可知行波法對(duì)牽引網(wǎng)故障測(cè)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
