Abstract

The embodiment of the invention provides a converter control system and a control method thereof. The system comprises at least one converter, a communication module, and a controller, wherein the controller is connected with each converter through the communication module; the converter is used for performing rectification processing and inversion processing on the electric energy of the power supply system to correspondingly obtain rectification parameters and inversion parameters; and the controller is used for acquiring the rectification parameters and the inversion parameters of each converter through the communication module, and controlling the rectification processing process of the at least one converter according to the rectification parameters, or controlling the inversion processing process of the at least one converter according to the inversion parameters.

Description

technical field [0001] The present application relates to the field of rail transit, and relates to but not limited to a converter control system and a control method thereof. Background technique [0002] The regenerative braking energy feedback device is mainly composed of insulated gate bipolar transistor (Insulated Gate Bipolar Transistor, IGBT). Taking a single converter device in each traction station as a working unit, each independently realizes the preset function. There is no system-level information interaction between each converter device and the power supply system, and it is impossible to quickly adjust according to the real-time needs of the system level, and it is difficult to realize accurate reactive power compensation and system-level functional requirements for the system. Contents of the invention [0003] In view of this, embodiments of the present application provide a converter control system and a control method thereof. [0004] The technical s...
