Abstract

The invention provides a wind generating set and a control method thereof. The wind generating set comprises at least two electric energy transmission systems and a control system, wherein the electric energy transmission systems are connected each other; the control system comprises an upper controller and control subsystems corresponding to all the electric energy transmission systems, and all the control subsystems comprise bottom controllers, wherein the bottom controllers are used for monitoring the operating state parameters of functional units in the corresponding electric energy transmission systems, and under the condition that it is determined that the corresponding functional units meet the abnormal conditions according to the operating state parameters, the operating state parameters of the corresponding functional units are sent to the upper controller; the upper controller is used for generating operating instructions under the condition that the breakdowns of the corresponding functional units occur according to the operating state parameters of the corresponding functional units, the electric energy transmission systems are controlled to work according to the instructions, the wind generating set is fully used, and the generating capacity of the wind generating set is further increased.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of wind power generation control, in particular to a wind power generating set and a control method thereof. Background technique [0002] A wind turbine is a power generation device that converts wind energy into mechanical energy, which drives the rotor to rotate, and finally outputs alternating current. In order to ensure the normal operation of the wind turbine, it is necessary to control each system of the wind turbine. For example, for permanent magnet direct-drive wind turbines, the torque control of the wind turbine, the control of the generator cooling system, the control of the converter cooling system, the pitch control, the braking control, the bias control, and the flight control etc. [0003] In the current overall structure of wind power generators, although the drive motor has a multi-winding structure, multiple converters can also be set up, and each converter adopts ...
