摘要： The invention relates to a wind turbine system (1) comprising a support structure (3) with a plurality of wind turbine modules (2) mounted to the support structure (3). A control system (20) is arranged to enter a service mode wherein service can be performed in the wind turbine system (1) by applying a first control command (1CC) to a first subset of wind turbine modules (2') for terminating power production. A second control command (2CC) is applied to a second subset of wind turbine modules (2'') for bringing the second subset of wind turbine modules (2'') 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 (2*) of the first subset of wind turbine modules. An improved stability of the wind turbine system during service is thereby obtained.

摘要： A method for erecting a multirotor wind turbine (10) is disclosed. A carrier structure (1, 1a, 1b) is arranged circumferentially with respect to a tower structure (2) and hoisted to an upper part of the tower structure (2), using a hoisting arrangement, such as a wire winch arrangement (3, 4, 8). Furthermore, energy generating units (5) may be hoisted to the carrier structure (1, 1a, 1b) using the hoisting arrangement (3, 4, 8). A similar method for dismantling a multirotor wind turbine (10) is also disclosed. The multirotor wind turbine (10) can be erected or dismantled without the need for an external crane.

摘要： The invention is directed to a wind turbine system comprising a first pair of wind turbines mounted to a support structure by a first support arm arrangement, and a second pair of wind turbines mounted to the support structure by a second support arm arrangement. The first and second support arm arrangements are mounted to the support structure at a respective yaw unit so as to yaw about the major axis of the support structure. Moreover, the wind turbine system further includes a control system that is configured to control the yaw angle of each of the first and second support arm arrangements, wherein the control system is configured to identify the presence of a predetermined shutdown condition and, in response, the control system is operable to control the yaw angles of the first support arm arrangement and the second support arm arrangement to a predetermined safe state.

摘要： 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.

摘要： A method for operating a wind turbine is disclosed. The wind turbine comprises a rotor having a set of wind turbine blades, said rotor being mounted on a tower. The method comprises the steps of: Providing a curve defining optimal pitch angle as a function of tip speed ratio for the wind turbine blades or as a function of wind speed. Modifying at least a part of said optimal pitch angle curve by applying a safety buffer, e.g. at tip speed ratios and/or pitch angles where there is a risk that the blades may stall and/or that overload is caused to the wind turbine, thereby obtaining a safety modified pitch angle curve. Operating the wind turbine in accordance with the safety modified pitch angle curve. Measuring one or more parameters providing information regarding wind conditions and/or loads on one or more components of the wind turbine, during operation of the wind turbine. Adjusting the safety buffer, based on said measurements, thereby obtaining an adjusted pitch angle curve, and operating the wind turbine in accordance with the adjusted pitch angle curve. The safety buffer is applied in order to ensure that the blades of the wind turbine do not stall and/or that the wind turbine is not overloaded, but it has the effect that the wind turbine is operated in a suboptimal manner from an energy production view. Since the safety buffer is adjusted based on measured parameters, it can be reduced if it is detected that the actual operating conditions are less severe than expected. This allows the wind turbine to be operated in a more optimal manner, thereby increasing the energy production of the wind turbine.

摘要： The invention provides a wind turbine comprising a wind-driven rotor for converting wind energy to a mechanical driving force, a power converter for converting the driving force to exploitable power and a transmission system for rotatably transmitting the driving force to the power converter. The transmission system comprises at least one rotatable driving element and a torsional dampening device having a rotatable inertia element which is drivable by the at least one rotatable driving element. The inertia element is connected in such a way to the at least one rotatable driving element that the inertia element dampens torsional vibrations in the rotatable driving element during operation of the wind turbine.
