Wiring structure of multiple distributed phase modifiers and operation method

Abstract

The invention discloses a wiring structure of multiple distributed phase modifiers and an operation method, and belongs to the technical field of distributed phase modifiers, the wiring structure comprises a distributed phase modifier group, the distributed phase modifier group comprises two first distributed phase modifiers and multiple second distributed phase modifiers, the first distributed phase modifier and the second distributed phase modifier are connected together through a connecting line, the distributed phase modifier group shares two sets of SFC systems, each set of SFC system comprises a first isolation switch, an SFC device, an SFC isolation transformer and a feeder switch which are sequentially connected with each first distributed phase modifier, and the feeder switch is connected with a 35kV bus. The two sets of SFC starting systems are standby for each other, the number of isolation transformers, SFC devices and SFC feeder switches in the SFC starting systems is greatly reduced, an electrical wiring system is simple, electrical equipment elements in wiring are reduced, the reliability of an electrical system is improved, equipment arrangement and occupied space are saved, overhaul and maintenance are facilitated, engineering investment is saved, and the cost is reduced. The economic benefit is obvious.
