Abstract
The present invention discloses a wind turbine yaw control method and system, the method comprising the following steps: establishing a reference model, giving the optimal yaw reference model different wind speeds for wind shift angles; using model reference adaptive control; getting the adaptive control input so that the difference between the actual yaw angle deviation of the wind and the optimal wind yaw angle deviation is at a minimum. The wind turbine yaw control method and system of the present invention can adaptively track the wind speed in different sections of the optimum wind yaw deviation, improve operating performance under the influence of factors such as wind direction measurement and bias of the yaw system in order to achieve maximum efficiency absorption of wind energy, as well as optimize wind turbine power generation to improve economic efficiency and the operation of the entire wind farm.
