The invention belongs to the technical field of wind electricity, and particularly relates to a wind turbine self-adaptation control method and device and a wind turbine. The method includes the steps that based on WRF weather forecast, in cooperation with measurement and control data of an anemometer tower, current flow coming data and wind speed data are obtained, and the main flow coming direction is judged; and the current flow coming data and the wind speed data are compared, if the current air speed is smaller than rated wind speed, the standing time of the main flow coming direction is judged according to the forecast and monitoring information, and yaw time is adjusted into the main flow coming direction if the standing time of the main flow coming direction exceeds a preset time. According to the wind turbine self-adaptation control method and device and the wind turbine, blades or impellers of the wind turbine can be automatically adjusted, the aims of damping, load shedding and efficiency increase are achieved, and the running safety of the wind turbine is increased.
