Abstract
A method of adjusting a yaw angle of a wind turbine. The wind turbine includes a nacelle that is rotatably coupled to a tower. The method includes coupling a yaw drive assembly to the nacelle for adjusting an orientation of the nacelle with respect to a direction of wind. A first sensor that is coupled to the wind turbine transmits at least a first monitoring signal that is indicative of an operating condition of the wind turbine to a control system. A yaw angle of the nacelle with respect to the direction of wind is calculated by the control system based at least in part on the first monitoring signal. The yaw drives assembly is operated to adjust a yaw of the nacelle based at least in part on the calculated yaw angle.
