Jing Ying Zhao · Dianli xitong zidonghua · 2006
How to locate the faults fast and precisely in railway automatic blocking and continuous power line (ABCPL) is a problem to be solved that is important to ensure the safe operation of the electrical railway systems. Based on the applications of the fault indicator in the fault location in power transmission lines, this paper proposes to implement fault location in railway ABCPL via the exploration node for power transmission line of railway combining with wireless communications, via, wireless node. In the paper, fault location principle based on wireless node is introduced, issues such as power supply, communication frequency, detecting parameter setting, etc, are addressed, the design of software and hardware systems is discussed, and the functions and characteristics of the method are analyzed with simulation results provided.
