Electrified railway digital traction substation automation system

Abstract

The present invention relates to an electrified railway digitized traction substation automation system, which includes a station control layer, an interval layer and a process layer, and is characterized in that an intelligent substation monitoring software and an interval layer device are installed on the integrated monitoring host of the station control layer Interconnection and intercommunication are realized through GOOSE, and the reorganization of networked protection and power supply systems is realized; the process layer is intelligent primary equipment/primary equipment with intelligent components; the intelligent primary equipment is electronic transformers, intelligent switches and intelligent transformers; The intelligent components include JDA‑331U voltage merging unit, JDA‑331M merging unit, JDA‑331C smart terminal, JDA‑331 merging smart unit, and JDA‑332 transformer body smart unit. The advantages of the present invention are: 1) The traditional primary equipment is intelligentized through intelligent components. 2) Support smart primary devices. 3) For the first time in the traction substation, the layered locking logic is realized, and the complete logic locking of the station control layer and the bay layer is combined with the electrical locking of the mechanism to meet the complex logic locking requirements.

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...
