Abstract

The embodiment of the invention provides a wind yaw-control parameter optimization method and device. The method comprises the steps of acquiring wind resource data of a target geographical environment; simulating yaw control over a wind power generator unit to acquire the simulation results of multiple wind yaw-control parameters of the target geographical environment according to the wind resource data and the multiple preset wind yaw-control parameters; conducting analysis on the simulation results of the multiple wind yaw-control parameters so as to classify the multiple wind yaw-control parameters; conducting optimization on the wind yaw-control parameters of the wind power generator unit according to different requirements of the target geographical environment and the classification. Through the wind yaw-control parameter optimization method and device provided by the embodiment of the invention, the wind yaw-control parameters of the wind power generator unit can be optimized according to the characteristics of wind resources of different geographical environments.

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...
