System for implementing continuous co-phase flexible alternating current traction power supply and operation mode therefor

Abstract

A system for implementing continuous co-phase flexible alternating current traction power supply and an operation mode therefor includes at least one flexible traction substation and neutral sections. Each flexible traction substation includes a first power inlet line and a second power inlet line, each of which is coupled to one end of a corresponding breaker, the other end of the corresponding breaker is coupled to a primary side of one traction transformer, and a secondary side of the traction transformer is coupled to a plurality of SPCs. SPCs corresponding to each set of traction transformer are coupled in parallel and coupled to a bus of the flexible traction substation through breakers. One feeder line is provided between the bus of the flexible traction substation and each of an up-track line and a down-track line of an overhead contact system, and each feeder line is provided with one up-to-net breaker thereon.
