摘要： A multirotor wind turbine comprising a tower, a suspension arm, a nacelle, and a rotor carried by the nacelle and configured to rotate about a rotor axis to drive a drive train in the nacelle, wherein the tower holds the suspension arm, and the suspension arm holds the nacelle. To facilitate safer and better access to the nacelle or drive train, the suspension arm is configured as a platform to provide support for personnel e.g. during maintenance and repair of the nacelle.

摘要： An applicator tool (40) for repairing damage (26) to a wind turbine blade (20) includes a spatula (42) including a flexible extrusion plate (44) and one or more spacers (60, 106) positioned proximate an inner surface (58) of the extrusion plate (44). The one or more spacers (60, 106) are configured to define a gap between an outer surface (34) of the wind turbine blade (20) and the inner surface (58) of the extrusion plate (44). A feed tube (86) is provided for supplying a coating material to the spatula (42), wherein the spatula (42) is configured to shape the coating material into a coating (30) over a damaged area (26) of the wind turbine blade (20).

摘要： A wind turbine comprising a tower structure configured to hold a nacelle with a rotor and a parking structure for holding the rotor. To improve the ability to carry out maintenance and to allow easier assembly and disassembly of the wind turbine, the parking structure is configured to connect the rotor directly to the tower structure to thereby allow removal of the nacelle while the rotor remains fixed to the tower structure.

摘要： A method of handling a wind turbine component (54) for assembly or maintenance, comprises coupling one or more unmanned air vehicles (20) with the wind turbine component (54) so that at least a portion of the weight of the wind turbine component (54) can be supported and lifted by the one or more unmanned air vehicles (20). The method further comprises coupling one or more cranes (50) with the wind turbine component (54) so that at least a portion of the weight of the wind turbine component (54) can be supported and lifted by the one or more cranes (50). The method further comprises controlling the one or more unmanned air vehicle (20) and crane (50) in coordination to lift the wind turbine component (54) and manoeuvre said component (54) with respect to a wind turbine (52).

摘要： A system for a wind park including: a control system in communication with a plurality of unmanned air vehicles, wherein the control system is configured to deploy one or more unmanned air vehicles during a triggering condition; and wherein the deployed unmanned air vehicles are guided towards an assigned wind turbine and to interact with a blade of that wind turbine in order to control oscillation of the blade. The invention also embraces a method for reducing blade oscillations of a wind turbine, comprising: monitoring for a triggering condition associated with the wind turbine; on detecting the triggering condition, deploying unmanned air vehicles towards a wind turbine and interacting with a blade of the wind turbine using the unmanned air to control oscillation of the blade. The invention therefore provides an efficient approach to controlling blade oscillations with minimal human operator involvement. Drones may be deployed automatically once suitable conditions are detected and may automatically engage with the blades, either by contacting those blades physically, or by interacting with the blades in close proximity, in order to disrupt airflow around the blades thereby reducing oscillations.

摘要： The invention relates to a method for lifting a component (1a, 1b) of a multirotor wind turbine (100) from an initial position to an operating position. The initial position is near a base (2a) of a tower structure (2) of the wind turbine (100) while the operating position is arranged at a distance from the tower structure (2), on a load carrying structure (3) connected to the tower structure (2) and extending away from the tower structure (2). By operating a first hoisting mechanism provided at or near a connecting point between the tower structure (2) and a load carrying structure (3), and a second hoisting mechanism provided at or near the operating position, the component (1a, 1b) is moved from the initial position to the operating position along a predetermined path. The component (1a, 1b) is finally mounted on the load carrying structure (3) at the operating position.
