Abstract: Two-level converter as a basic parallel module unit can effectively improve the power level of the wind power converter,but the signals collected by the controller and the corresponding control signals increase with the increasing of the parallel branches,which will directly affect the utilization of hardware resources of the controller.On the other hand,multi-branch parallel systems set higher requirements for the speed and reliability of the control system.This paper takes a squirrel cage wind power parallel converter system as the research object,with a high-speed optical-fiber communication coordinated control method of a master controller and multiple sub-controllers,and realized the effective and rapid control of parallel converter system finally.
