  • Yaw control method, device and system for wind turbine
    Patent number: 11174842
    Abstract: A yaw control method for a wind turbine, comprising the following steps: acquiring the current or future ambient wind speed and yaw angle of a wind turbine; estimating a power change value of the wind turbine caused by performing a yaw action on the basis of the yaw angle at the ambient wind speed; determining a yaw control strategy of the wind turbine according to the estimated power change value; transmitting a command to the wind turbine, so as to enable the wind turbine to perform the determined yaw control strategy. In addition, also provided are a device and system for performing the control method. The yaw control method, device and system can lower the loss of the wind turbine, reduce the overall load under certain extreme working conditions, and can also exploit the power generation potential of the wind turbine.
