Abstract: Wind turbine pitch actuator mounting structure A mounting structure is described for attaching a pitch actuator to a hub of a wind turbine. The mounting structure has one or more legs each having a proximal end and a distal end, and a flexible intermediate portion between the proximal and distal ends. The mounting structure further comprises an actuator attachment portion for attaching to a wind turbine blade pitch actuator. The actuator attachment portion is arranged at the distal end(s) of the one or more legs. The proximal end(s) of the one or more legs are configured for attachment to a wind turbine hub. The flexible intermediate portion(s) of the one or more legs are configured to flex in use to absorb loads acting on the pitch actuator. The mounting structure therefore allows the pitch actuator to pivot in a first plane by virtue of the flexible legs. The pitch actuator may be attached to the mounting structure via pivot bearings arranged to allow the pitch actuator to pivot in a second plane, substantially perpendicular to the first plane.

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.

IPC: F03D7/02
Abstract: There is provided a method for controlling a hydraulic pitch force system (220) so as to reduce or eliminate a decrease in hydraulic oil pressure (241) if a hydraulic system parameter value is outside a hydraulic system parameter range, the method comprising: Obtaining (690) the hydraulic system parameter value, and operating the hydraulic pitch force system (220) according to a reduced mode (692) if the hydraulic system parameter value is outside the hydraulic system parameter range, wherein in the reduced mode one or more pitch based activities are reduced (694) or suspended. An advantage thereof may be that it enables keeping the wind turbine in production in certain instances rather than shutting down the wind turbine. In aspects, there is furthermore presented a computer program product, a pitch control system (250) and a wind turbine (100).

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.

Abstract: A wind turbine is described which comprises a tower, a nacelle mounted to the top of the tower, and a rotor mounted to the nacelle. The rotor comprises two or more blades mounted to a central hub. The hub supports two or more annular pitch bearings associated respectively with the two or more blades. Each pitch bearing defines a bearing plane inclined at a first angle with respect to a horizontal plane when the respective blade is oriented in a downwardly direction in alignment with the tower. Each pitch bearing is spanned by a hub plate; and a work platform integral with or mounted to the hub plate lies generally in a plane at a second angle to the horizontal plane when the respective blade is oriented in a downwardly direction in alignment with the tower, which second angle is less than the first angle. The work platform provides a substantially horizontal platform for use by maintenance personnel when installing or servicing components in and around the hub.

Abstract: Techniques for controlling the yaw of a wind turbine system by controlling a plurality of yaw drive actuators.
When the yaw drive actuators are applying the same torque to all the motors, this can lead to some motors overspeeding, if the motor is not engaged when the yaw system is activated.
Therefore, if the actual motor speed reference of a yaw drive actuator is higher than a specific motor speed reference, then an output signal to reduce the actual motor speed reference is applied to the yaw drive actuators with an actual motor speed reference higher than the specific motor speed reference.
