Wind turbine generator control method and device and electronic equipment

Abstract

The invention provides a wind turbine generator control method and device and electronic equipment, and relates to the technical field of wind power. The wind turbine generator control method comprises the following steps that a pre-established three-dimensional database is obtained, wherein the three-dimensional database stores wind energy utilization coefficients corresponding to each pitch angle and blade tip speed ratio; the current average wind speed is obtained, and the incoming flow wind speed of a fan blade at each preset equivalent pneumatic center position is determined based on the average wind speed; and the optimal pitch angle of the fan blade at the preset equivalent pneumatic center position is determined based on the incoming flow wind speed and the three-dimensional database, and variable pitch control is conducted on the wind turbine generator based on the optimal pitch angle so that the wind energy absorption rate of the wind turbine generator can reach the maximum. The wind energy capturing efficiency of a wind turbine generator can be effectively improved, and the generating capacity of the wind turbine generator is increased.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a control method, device and electronic equipment for a wind turbine. Background technique [0002] With the continuous maturity of wind power technology, wind turbines tend to develop in the direction of large capacity, tall towers and long blades. As the size of the wind rotor increases, the aerodynamic performance of the blades varies greatly due to the influence of the wind shear effect when the blades operate at different position angles. However, the existing wind turbine control technology does not take into account the difference in the aerodynamic performance of the blades at different rotor angle positions, and mainly controls the wind turbine based on the equivalent wind speed of the rotor to achieve optimal control of power generation efficiency. In the wind speed stage, there is still a lot of room for improvement in the wind energy capture efficiency of wind tur...
