Autonomous Decentralized Architecture Based Protection and Supervisory Control System of Railway Automatic Blocking and Continuous Transmission Line

The architecture and features of Autonomous Decentralized System (ADS) were introduced, the functions, architecture features of railway automatic blocking and continuous transmission line (RACL) and its protection and supervisory control system (RACLPSS) were analyzed, then autonomous decentralized based RACLPSS was put forward, its architecture and operation mechanism were analyzed. Finally, fault location in transmission line protection and supervisory control system (LPSS) was taken as an example to describe the application of autonomous distributed mechanism in RACLPSS. Autonomous decentralized based RACLPSS can ensure the easy realization of on-line expansion, on-line maintenance and fault tolerance, meet the new demand put forward by continuously changed system, it has a good prospect in protection and supervisory control system.
