Abstract: The invention relates to a wind turbine system comprising a support structure with a plurality of wind turbine modules mounted to the support structure. A control system is arranged to enter a service mode wherein service can be performed in the wind turbine system by applying a first control command to a first subset of wind turbine modules for terminating power production. A second control command is applied to a second subset of wind turbine modules for bringing the second subset of wind turbine modules into an damping mode where each of the wind turbine modules of the second subset is operated and/or positioned to damp vibrations, actively and/or passively, of at least one wind turbine module of the first subset of wind turbine modules.

Abstract: A method for controlling a multirotor wind turbine is disclosed. A first operational state of each of the energy generating units of the wind turbine is obtained. A difference in thrust acting on at least two of the energy generating units is detected. At least one constraint parameter of the set of operational constraints is adjusted in accordance with prevailing operating conditions and in accordance with the detected difference in thrust, and a new operational state for at least one of the energy generating units is derived, based on the at least one adjusted constraint parameter, the new operational state(s) counteracting the detected difference in thrust. Finally, the wind turbine is controlled in accordance with the new operational states for the energy generating units.

Abstract: The invention relates to a method of controlling a wind turbine, the wind turbine comprising wind turbine blades attached to a rotor hub and a control system for pitching the blades relative to the rotor hub. The method comprises determining a wind speed and providing a normal pitch mode of operation to control the output power of the wind turbine, where the pitch mode of operation comprises pitch reference values in dependence of the wind speed. The output power of the turbine is controlled according to the normal pitch mode of operation as a function of the wind speed if the wind speed is lower than a first upper level wind speed threshold, and according to a modified mode of operation if the wind speed exceeds the first upper level threshold wind speed, wherein the modified mode of operation comprises decreasing the output power according to a de-rating function which is a function of time. The invention further relates to a control system for controlling a wind turbine according to the above mentioned control method.

Abstract: The invention relates to a method for monitoring performance of a multi-rotor wind turbine. According to the method parameter for each of the wind turbine modules of the multi-rotor wind turbine is obtained. The parameters of each of the wind turbine modules are compared, e.g. by means of a comparison parameter determined from the individual parameters. Dependent on the result of the comparison, a performance action is initiated, e.g. for the purpose of further characterization or verification of a deviating parameter determined via the comparison.

Abstract: A wind turbine system comprising a plurality of wind turbines mounted to a support structure including a tower, wherein each of the plurality of wind turbines includes a rotor and a power generation system driven by the rotor, and at least one of a rotor blade pitch adjustment means and a generator power control means. The system further includes control means that receives vibration data associated with the support structure and which is configured to determine a damping control command for a respective one of the plurality of wind turbines, wherein the or each of the wind turbines includes a damping controller that receives a damping control command and which is operable to apply a damping control input to one or both of the blade pitch adjustment means and the generator power control means so as to counteract the measured vibration of the support structure. A benefit of the invention is that the operation of the multiple turbines of the system is used to reduce the effects of structural vibration by damping that vibration in an active manner.

Abstract: A method is disclosed for calibrating a wind turbine sensor placed on a component of a wind turbine and where the wind turbine is of the type having a rotor with at least one pitchable wind turbine blade. The method comprises pitching one or more of the blades according to a predetermined pitch movement and detecting the response signal from the wind turbine sensor at least partly caused by the pitch movement. From this is then determined a characteristic sensor response value which upon comparison to a predetermined sensor calibration parameter forms the basis for a calibration of the wind turbine sensor if needed. The characteristic sensor response value may be determined from the pitch movement having been performed a number of times over a longer period of time.The invention further relates to a control system and a wind turbine configured for performing the method.

Abstract: The invention relates to a wind turbine system (1) with several wind turbine modules (2) mounted to a support structure (3). A control system is configured to determine a lift command (21) for a particular wind turbine module (2′) of the 5 plurality of wind turbines modules (2). The control system is applying the lift command (21) to a corresponding rotor blade pitch adjustment system of the particular wind turbine module (2′) so as to create a lift force (F_up) in the opposite direction of gravity on the particular wind turbine module mounted on the support structure. Providing an upwards lift force on one, or more, particular 10 wind turbine module(s) may reduce, or eliminate, static and/or dynamical loads from the wind turbine module on the support structure.
