Description

technical field [0001] Embodiments of the present invention relate to the technical field of wind power generation, and in particular to a method and device for optimizing yaw versus wind control parameters. Background technique [0002] The wind in nature changes in real time. To improve the utilization efficiency of wind energy for wind turbines, a corresponding yaw-to-wind control strategy is required so that the rotating surface of the impellers of the wind turbines faces the direction of the wind as much as possible. At present, the yaw and wind control strategy of wind turbines is based on the wind direction signal of the nacelle. It generally compares the wind direction signal of the nacelle with a preset deviation threshold after being filtered by a filter. If the wind direction signal of the nacelle continues to exceed the preset deviation threshold within the preset time range (delay time), the wind turbine will generate a yaw The result of driving against the win...

Problems solved by technology

Therefore, there are problems such as relatively fixed parameter settings, lack of pertinence, long effect verification period, large errors, and non-optimal parameters, and unreasonable yaw-to-wind control parameter settings will cause low wind energy capture efficiency of the unit and loss of power generation, or It is caused by frequent yaw movements, long yaw time, increased crew yaw fatigue load, and increased wear of yaw mechanical parts.
