Abstract

The invention discloses an intelligent traction substation protection system for a railway. The system comprises a CPU unit, a communication unit, an input and output unit, and a power supply unit. The CPU unit is used for controlling data exchange among all parts. The communication unit is used for realizing communication between a spacing layer and a process layer. The input and output unit is used for realizing port configuration, program downloading, debugging, and communication with the CPU unit. The power supply unit is used for providing power for all units. On the basis of the structure, the sampling data communication and tripping command levels of the protection configuration scheme of the intelligent traction substation of a railway can be increased.

Description

technical field [0001] The invention relates to the field of substations, in particular to a railway intelligent traction substation protection system. Background technique [0002] The substation automation system includes substation layer, bay layer, and process layer. The substation layer includes background monitoring, telecontrol communication unit, and GPS time synchronization device; the bay layer is composed of various protection measurement and control devices, AC and DC screens and other third-party equipment; the process layer consists of It consists of intelligent operation box, merging unit and electronic transformer, and it can also be a conventional switch and transformer. Compared with the application of power system, in the traction power supply system, there is only one local monitoring computer at the substation level to complete all the background monitoring functions, and the telecontrol communication unit completes the telecontrol communication tasks. T...
