Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0031] Such as figure 2 As shown, the wind turbine control method of the present embodiment dynamically adjusts the size of the forbidden area of ​​the speed forbidden zone of the wind turbine according to the size of the turbulent velocity of the wind; when the turbulent velocity is large, the size of the forbidden zone of the speed forbidden zone is reduced; when the turbulent velocity is small, the size of the forbidden zone of the rotational speed is expanded The size of the restricted area.

[0032] In this embodiment, the specific way of dynamic adjustment includes: setting at least two restricted area intervals with different sizes, and setting corresponding trigger conditions for each restricted area interval. When the turbulent velocity meets the trigg...

Abstract

The invention discloses a wind turbine control method, controller and device. The method includes: dynamically adjusting the size of the restricted area of ​​the speed forbidden area of ​​the wind turbine according to the magnitude of the turbulent velocity of the wind; reducing the area of ​​the restricted area of ​​the rotational speed when the turbulent velocity is high The size of the forbidden area; when the turbulent velocity is small, the size of the forbidden area of ​​the speed forbidden area is enlarged. It has the advantages of effectively avoiding the resonance between the natural frequency of the tower and the rotation frequency of the wind turbine, effectively reducing the loss of power generation, good flexibility, and strong adaptability.

Description

technical field [0001] The present invention relates to the technical field of wind turbine control, in particular to a wind turbine control method, controller and device, in particular to a wind turbine control system capable of avoiding the resonance between the natural frequency of the wind power tower and the rotation frequency of the wind turbine, and with small loss of power generation. Method, controller and device. Background technique [0002] At present, the towers of wind turbines are getting higher and higher, especially in wind farms with high wind shear. The annual average wind speed of wind farms increases with the increase of tower heights. Under normal circumstances, the height of the tower will increase the annual power generation of the wind farm, improve the economic index of the wind farm, or make the wind resource area with low annual average wind speed but high wind shear have development value. According to the current technology, the height of the t...
