Embodiment Construction
[0023] It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict. Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.
[0024] The yaw control method of a wind turbine in this preferred embodiment is taken as an example:
[0025] At least two yaw driving devices for driving the wind turbine to yaw are arranged according to the wind speed load of the wind farm. The number of yaw drive devices can be the size and range of the actual load value of the yaw drive, and the rated power of each yaw drive device and the number of yaw drive devices can be selected. The yaw drive device can adopt an electric or hydraulic drive device, such as an electric motor or a hydraulic motor. In addition, it is also necessary to divide the wind speed gears according to the wind speed of the wind farm. When dividing the win...
