摘要
铁路自闭／贯通线路故障的快速精确定位,一直是困扰电气化铁路安全运行的技术难点。在分析故障指示器在电力输配电线路故障定位应用效果的基础上,提出结合无线通信设计铁路供电线路适用的故障探测节点,即线上无线节点,来实现铁路自闭／贯通线的故障定位。介绍了基于线上节点的定位实现原理,并针对自闲贯通线路特点,通过理论分析和仿真实验相结合,提出了节点供电方式、通信频率、检测参数设置值等关键问题的解决方案,实现了线上无线节点的软硬件设计,总结了所设计节点的功能特点。
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 nines, 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.
