Abstract: A method of damping oscillations in a multi-rotor wind turbine and a wind turbine are provided. The wind turbine comprises a wind turbine support structure and at least a first nacelle with a first rotor and a second nacelle with a second rotor, at least one of the nacelles being located at a position away from a central longitudinal axis of the wind turbine support structure. The method comprises the steps of receiving and processing motion data, selecting a damping algorithm and generating a pitch control signal. The processing comprises determining at least one prominent oscillation mode of the wind turbine support structure and selecting a corresponding damping algorithm.

Abstract: A first aspect of the invention provides a method of testing a yaw system (200) of a wind turbine, the wind turbine comprising a rotor; the yaw system (200) comprising a yaw gear (202) coupled to the rotor so that rotation of the yaw gear (202) causes yaw rotation of the rotor, and first and second sub-systems (204a, 204b), the first sub-system (204a) comprising a first pinion gear (206a) and a first drive motor (208a) coupled to the yaw gear (202) by the first pinion gear (206a), the second sub-system (204b) comprising a second pinion gear (206b) and a second drive motor (208b) coupled to the yaw gear (202) by the second pinion gear (206b). The method comprises the steps of: testing the first sub-system (204a) by: applying a first yaw moment to the yaw gear (202) with the second drive motor (208b) via the second pinion gear (206b), reacting the first yaw moment with the first pinion gear (206a), monitoring a yaw motion parameter indicative of rotation of the yaw gear (202), and determining a condition of the first sub-system (204a) based on the monitored yaw motion parameter.

Abstract: A method of protecting a multi-rotor wind turbine support structure (101) against vibration induced overload is provided. The wind turbine (100) comprises at least a first nacelle (111) with a first rotor (110) and a second nacelle (121) with a second rotor (120), at least one of the nacelles (111, 121) being located at a position away from a central longitudinal axis (102) of the wind turbine support structure (101). The method comprises steps of receiving motion data ( ÿ 0 , ÿ 1 , ÿ 2 ), determining a vibrational mode level and activating a safety mode if a vibrational mode level exceeds a respective vibrational mode threshold. The motion data ( ÿ 0 , ÿ 1 , ÿ 2 ) represents a movement of the first nacelle (111) and of the second nacelle (121) and is used for determining the vibrational mode level of at least one vibrational mode of the wind turbine support structure (101).
