An Advanced Study on Fault Location System for China Railway Automatic Blocking and Continuous Transmission Line

Based on the analysis of the applicability of various fault location methods in railway automatic blocking and continuous transmission line (RABCTL), S-injection method is considered to be a feasible method. An advanced S- injection applied in fault location system is put forward. Based on the traditional S-injection, the technology of wireless sensor network is brought in. It can realize wireless detector to network automatically in certain range, and improve the flexibility of communication system. The theory of the fault location system is presented, some key problems in practical process of fault location are researched, and the design of wireless detector is briefly introduced in the paper.
