Abstract

One or more embodiments of the invention provide a parallel cooperative control method of a bidirectional converter and a traction rectifier and related equipment. According to the method, the bidirectional converter is provided with a first working state, a second working state and a third working state, and the bidirectional converter is switched among the working states according to the output total power characteristic of a parallel branch formed by the bidirectional converter and a traction rectifier, so that while the stability of the system operation is ensured, parallel branch power distribution is flexibly adjusted, circulation is prevented, and stable switching of working modes of the bidirectional converter is guaranteed.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of subway train traction control, and in particular to a parallel coordinated control method of a bidirectional converter and a traction rectifier and related equipment. Background technique [0002] In urban rail transit, multi-pulse traction rectifiers (hereinafter referred to as traction rectifiers) are used to supply energy to trains. The traction rectifier is a diode rectifier, which can only realize one-way transmission of energy from the AC network for power transmission to the DC network for powering subway trains. When the subway train brakes, the kinetic energy is converted into electric energy and fed into the DC network, causing the network voltage to rise, which can only be consumed by means of braking resistors or mechanical braking. At present, bidirectional converters are used in the field of rail transit to feed braking energy into the AC network in the form o...
