The Application of Traveling Wave in Fault Location for Railway Automatic Blocking and Continuous Power Transmission Lines

The accurate fault location of automatic blocking and continuous power transmission lines has the signification for improving power supply reliability systematically. Through consulting relevant documents, the paper introduce the basic method to fault location based traveling waves and already solving the key technology at the present time. Combined the characteristic of automatic blocking and continuous railway power transmission lines, the paper summarizes the existing problems of the traveling waves of application and its solving measures. The traveling-wave fault location applied in Automatic blocking and continuous railway power transmission line that needs much more research. Its content and difficulty are represented in this paper at last.
