基于C型行波法的电气化铁路牵引网故障测距研究

Study on C Traveling Wave Method Based Fault Location for Electrified Railway Traction Network

针对目前电气化铁路牵引网故障测距方法精度不高的问题,根据牵引网特点将行波法应用于牵引网故障测距中,建立基于A、B、C型行波检测装置的3种牵引网模型,针对有站场和无站场2种不同工况进行仿真,对比分析不同型号行波检测装置的检测精度,并给出以C型行波法判断为主,A、B型行波法判断为辅的牵引网故障测距方案。

With regard to the problem that the accuracy of fault location of electrified railway traction network is not high, and on the basis of application of traveling wave method in electrified railway traction network in accordance with the characteristics of traction network, 3 types of traction network models based on the A, B, C traveling wave inspection devices are established to simulate two working conditions with yard/without yard, compare and analyze the accuracy of different types of traveling wave inspection devices; a scheme is provided for fault location of traction network, in which, the assessment is made mainly by C traveling wave method, assisted by A, B traveling wave methods.
