Electrified railway digital traction substation automation system

Abstract

The invention relates to an electrified railway digital traction substation automation system. The system comprises a station control layer, an interval layer and a process layer. The system is characterized in that the integrated monitoring host of the station control layer is provided with intelligent substation monitoring software, the devices of the interval layer are connected and communicatewith one another through GOOSE, and therefore, networked protection and the reorganization of a power supply system can be realized; the process layer configures intelligent components for intelligent primary devices / primary devices; the intelligent primary devices are electronic transformers, intelligent switches, and intelligent transformers; and the intelligent components include a JDA-331U voltage merging unit, a JDA-331M merging unit, a JDA-331C intelligent terminal, a JDA-331 merging intelligent unit, and a JDA-332 transformer body intelligent unit. According to the electrified railwaydigital traction substation automation system of the present invention, the intellectualization of traditional primary devices is realized through the intelligent components; the intelligent primary devices are supported; hierarchical locking logic is realized in a traction substation; and the complete logic locking of the station control layer and the interval layer is combined with the electrical locking of a mechanism, so that complex logic locking requirements can be satisfied.

Description

technical field [0001] The invention belongs to the field of traction power supply for electrified railways, in particular to an automation system for digitized traction substations of electrified railways. Background technique [0002] In recent years, my country's railway construction and development have made great achievements, and people have put forward higher requirements for the development of railways. The existing problems of digital traction substations for electrified railways are: (1) The signal output and control input of traditional primary equipment use analog signals, which have low operating efficiency and poor safety performance. (2) The adoption of conventional relay equipment in the design of the secondary circuit leads to the occupation of a large amount of cultivated land for the construction of the substation, resulting in a waste of land resources. (3) All information collection, transmission, processing, and output processes still use analog inform...

Problems solved by technology

The problems existing in the existing digitized traction substations of electrified railways are: (1) The signal output and control input of the traditional primary equipment use analog signals, which have low operating efficiency and poor safety performance

(2) The adoption of conventional relay equipment in the secondary circuit design leads to the occupation of a large amount of cultivated land for the construction of substations, resulting in a waste of land resources

(3) All information collection, transmission, processing, and output processes still use analog information, and information sharing cannot be realized, and the control function of the substation cannot be optimized, resulting in low operating efficiency
