Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] The wind power generating set operates in an area with high turbulence intensity, and its power generation performance and life are affected. Through the method of suppressing turbulence intensity proposed by the present invention, the influence of high turbulence intensity on the generating set is weakened, thereby ensuring the power generation performance and life of the generating set .

[0026] Such as figure 1 As shown, the present invention measures the real-time wind speed through the anemometer on the wind turbine nacelle, the wind vane measures the real-time wind direction, and the wind generator controller calculates the turbulence factor under the real-time wind condition according to information such as real-time wind speed and real-time wind direction, and determines the wind farm unit Located in a high turbulence intensity...

Abstract

The invention relates to a method for inhibiting the turbulence effect on a wind generating set. When the wind generating set is in operation, the real-time wind speed is measured through an anemometer, the real-time wind direction is measured through a wind vane, the turbulence factor under the real-time wind condition is calculated by a wind generator controller according to the real-time wind speed and the real-time wind direction, and the wind generating set is controlled by taking the turbulence factor as the control target during the yaw control process of the wind generating set, so as to inhibit the influence of the turbulence intensity on the wind generating set, and ensure the generating efficiency and the service life of the wind generating set.

Description

technical field [0001] The invention relates to a method for suppressing the influence of turbulence when a wind power generating set operates under complex wind conditions such as high turbulence. Background technique [0002] The wind turbine absorbs wind energy through the rotation of the blades, converts the wind energy into the kinetic energy of the impeller rotation, transmits the kinetic energy through the gearbox (for direct drive permanent magnet wind turbines, there is no such link), and converts the kinetic energy through the generator Finally, the generated electric energy is sent out through the transmission network. [0003] The changes of wind in nature are very complicated, and its size and direction are changing all the time, which brings great challenges to wind turbines to absorb wind energy safely and effectively. The first is whether the wind turbine can have real-time and accurate measurement of wind speed and wind direction; the second is whether the ...
