Problems solved by technology
[0003] However, while the multi-winding wind turbines bring high power output, they also have a high probability of failure
Now, as long as any winding failure occurs in the multi-winding wind turbine generator set, the generator set needs to be shut down and cut off from the grid, and can only continue to run after the repair of the faulty winding is completed. During this fault period, the availability and power generation of the generator set are zero. , which results in reduced performance of the unit

Embodiment Construction
[0036] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0037]In the present invention, when all the windings and related systems included in the wind generating set are working normally, the operation of the wind generating set is controlled based on the design speed-torque curve of the wind generating set. Here, the design speed-torque curve can be any speed-torque curve designed for the wind power generating set when all windings and related systems are working normally, and the present invention does not impose any limitation on the design method of the design speed-torque curve.
[0038] figure 1 A flowchart showing a control method of a wind power generating set including multiple windings according to an embodiment of the present invention.
[0039] refer to figure 1 , in step S110, determine the maximum output power of the wind power generating set based on the number of windings currently in normal opera...

The invention provides a wind turbine generator unit comprising multiple windings and a control method and control device thereof. The control method of the wind turbine generator unit comprising themultiple windings. The control method is characterized by comprising the steps of determining the maximum output power of the wind turbine generator unit based on the current number of the windings operating normally; determining a rotating speed and torque curve corresponding to the maximum output power; and controlling operation of the wind turbine generator according to the determined rotatingspeed and torque curve.
Description
technical field [0001] The present invention relates to the field of wind power generation, more specifically, to a wind power generating set including multiple windings, a control method and a control device thereof. Background technique [0002] Wind energy is a clean and renewable resource, and its use has been paid more and more attention by countries all over the world. With the development of the world's energy crisis, wind power generation using wind turbines including multiple windings has become a hot spot in social development. [0003] However, while the multi-winding wind turbines bring high power output, they also have a high probability of failure. Now, as long as any of the windings of the multi-winding wind turbine fails, the unit needs to be shut down and cut off from the grid, and the operation can only continue after the repair of the faulty winding is completed. During this fault period, the availability and power generation of the unit are zero. , whic...
