SYSTEM AND METHOD FOR CONTROLLING A WIND TURBINE

摘要

A method is provided for controlling the rotation speed of a rotor having one or more blades on a wind turbine. The method comprises determining the yaw angle of the wind turbine relative to the wind direction. Then the yaw angle of the wind turbine is changed to increase or decrease the aerodynamic efficiency of the one or more blades, thus, controlling the rotation speed of the one or more blades.
