Embodiment Construction

[0031] 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.

[0032] Such as figure 2 As shown, the wind turbine control method of this embodiment dynamically adjusts the size of the speed forbidden zone of the wind turbine according to the size of the wind turbulence; when the turbulence is large, the speed forbidden zone is reduced; when the turbulence is small, the speed forbidden zone is expanded.

[0033] 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 flow satisfies the trigger condition, the restricted area area corresponding to the trigger condition As a speed forbidden zone of wind turbines. In this example, if image 3 As sh...

Abstract

The invention discloses a wind turbine generator control method, controller and device. The control method comprises the following steps that the interval size of a rotating speed forbidden zone of the wind turbine generator is dynamically adjusted according to the turbulent flow size of wind; the interval size of the rotating speed forbidden zone is reduced when the turbulent flow is large; and the interval size of the rotating speed forbidden zone is expanded when the turbulent flow is small. The wind turbine generator control method, controller and device have the advantages that the natural frequency of a tower frame and the rotating frequency of the wind turbine generator to generate resonance are effectively avoided, the electric energy production loss is effectively reduced, the flexibility is high, and the adaptability is high.

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...
