    Abstract: Aspects of the present invention relate to a nacelle (14) for a wind turbine generator (10), and a method for transferring components into and out of a wind turbine generator (10). The nacelle (14) comprises a housing (26) surrounding an internal volume (24) of the nacelle (14). The housing (26) has a maintenance opening (50). The nacelle comprises a carriage (54) configured to hold a component (48), the carriage (54) being movable between a first position and a second position to transfer the component (48) through the maintenance opening (50). When the carriage (54) is in the first position, the component (48) is held within the internal volume (24). When the carriage (54) is in the second position, the component (48) is held such that at least a portion of the component (48) is outside the housing (26).

    Abstract: A wind turbine comprising, a tower, a nacelle mounted on the tower, and a rotor for harvesting wind energy by rotation of the rotor about a rotor axis extending in a vertical center plane. The nacelle comprises a main unit and two auxiliary units each housing a first and a second operative component. To obtain a combination of reuse of components and a good weight distribution, the first operative components in the first and second auxiliary units have the same distance to the center plane and the second operative components in the first and second auxiliary units have different distances to the center plane.

    Abstract: A set of units for assembly to form a wind turbine nacelle. The nacelle comprises a rotor-supporting assembly and generator, and a power conversion assembly and the set of units comprises a main unit arranged to be connected to a wind turbine tower and housing the rotor-supporting assembly and the generator, and at least two different auxiliary units each housing an operative component forming part of the power conversion assembly. To allow different wind turbine configurations, one of the auxiliary units can be selected from the at least two auxiliary units and assembled with the main unit to form the nacelle.

    Abstract: A wind turbine comprising at least two separate units assembled to form a nacelle connected to a wind turbine tower. A first of said two units houses a rotor-supporting assembly and a generator. To enable a large degree of flexibility and the ability to reconfigure, a second of said two units houses an electrolysis cell stack powered by the generator.

    Abstract: The present invention relates to a method for operating a wind turbine (1). The wind turbine (1) comprises one or more wind turbine blades (5), each wind turbine blade (5) being connected to a blade carrying structure (4) mounted on a hub (3), via a hinge (6) at a hinge position of the wind turbine blade (5), each wind turbine blade (5) thereby being arranged to perform pivot movements relative to the blade carrying structure (4) between a minimum pivot angle and a maximum pivot angle. The method comprises the steps of detecting an airborne object entering a predefined zone around the wind turbine (1), comparing a current tip height (H) of the wind turbine (1) to a maximum tip height value, the maximum tip height value representing a maximum allowable tip height under currently prevailing conditions. In the case that the current tip height (H) exceeds the maximum tip height value, a pivot angle (P) of wind turbine blades (5) is adjusted in order to decrease the tip height (H) of the wind turbine (1) to a value below the maximum tip height value.

    Abstract: The invention provides a wind turbine comprising a load carrying structure and an energy generating unit. The load carrying structure is connected to the energy generating unit and holds the energy generating unit above ground. The energy generating unit houses a facility which requires a particular orientation relative to gravity for being operational. Furthermore, the energy generating unit comprises an adaptation structure e.g. arranged between the load carrying structure and the facility. The adaptation structure facilitates a first configuration with a first position of the facility relative to the load carrying structure, and a second configuration with a second position of the facility relative to the load carrying structure.

    Abstract: A wind turbine system comprising a plurality of wind turbine modules mounted to a support structure, wherein each of the wind turbine modules comprises a rotor including one or more variable-pitch blades, each defining a respective blade pitch angle and being controlled by a pitch control system, and a control system operable to control the blade pitch angles of the plurality of blades of the wind turbine modules. The control system is configured to identify the presence of a predetermined stop condition and, in dependence thereon, is operable to control the blade pitch angles of the respective blades to predetermined stop positions that reduce oscillation of the support structure. Aspects of the invention also relate to a method of controlling a wind turbine system, to a controller for implementing the method, and to a computer program product.

    Abstract: A wind turbine nacelle configured for mounting on a wind turbine tower and for supporting a rotor assembly, the nacelle comprising at least a first and a second nacelle module. The first nacelle module comprises a first frame structure and a main bearing system for a main shaft of the rotor assembly, and the second nacelle module comprises a second frame structure and a drive train system for the wind turbine. When the nacelle is mounted on the wind turbine tower, the main bearing system is supported by the wind turbine tower, and the drive train system is attached to the main bearing such that the weight of the drive train system is transferred to the main bearing system and thereby to the wind turbine tower. Further, the first frame structure is configured to support the main bearing system during transportation and prior to mounting of the nacelle, and the second frame structure is configured to support the drive train system during transportation and prior to mounting of the nacelle, and the first and second frame structures form a load carrying structure of a first and a second shipping freight container such that the first and second nacelle module can be transported as shipping freight containers. When the nacelle is mounted on the wind turbine tower, the first and second frame structures may be placed side by side in a direction along a rotational axis of the wind turbine rotor and may be oriented such as to have a length extending transversely to a rotational axis of the wind turbine rotor.
