  • Method for controlling the pitch angle of at least one wind turbine blade
    Patent number: 10036367
    Abstract: The invention regards a method for controlling the pitch angle of at least one wind turbine blade in a rotor connected to a main shaft on a wind turbine, the method comprises the steps of determining; a first component of the wind vector which is upwind, horizontal and aligned with the main shaft direction and, a second component of the wind vector which is upwind, perpendicular to the first component of the wind vector, wherein the first component of the wind vector and the second component of the wind vector are determined by use of at least one ultrasonic sensor mounted on the rotor, whereby the pitch angle is controlled based on the first component of the wind vector and the second component of the wind vector.
