    摘要: It is described a method and a control device (160) for damping an oscillatory movement of the top of a tower (120) of a wind turbine (100). The described method comprises (a) rotating a rotor (110) being rotatably attached to a nacelle (122) of the wind turbine (100) with a rotational speed, and (b) yawing the nacelle (122) of the wind turbine (100) around an axis being aligned with the longitudinal axis of the tower (120) with a yawing speed. Thereby, a yawing movement being associated with yawing the nacelle (122) is coordinated with the oscillatory movement in such a manner that a gyroscopic torque resulting (i) from rotating the rotor (110) and (ii) from yawing the rotor (110) damps the oscillatory movement of the top of the tower (120). It is further described a wind turbine comprising such a control device and a computer program for controlling this method.
