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 wind turbine comprising, a tower, a nacelle mounted on the tower, and a rotor defining a rotor axis extending in a vertical center plane and configured for harvesting wind energy by rotation of blades in a rotor rotation direction about the rotor axis. The nacelle comprises a rotor-supporting assembly forming a load path from the rotor to the tower and configured for receiving rotor torque caused by the rotation of the rotor. To reduce loading of the tower and potentially provide a cheaper construction, the nacelle has a center of gravity which is offset from the center plane in a direction relative to the rotor rotation direction to counteract the rotor torque.

Abstract: A wind turbine nacelle configured for mounting on a wind turbine tower and for supporting a rotor-supporting assembly, the nacelle comprising a main unit, and at least one auxiliary unit. The auxiliary unit accommodates at least one operative component, e.g. a converter, a transformer, an electrolysis cell, or a battery. An operative component having a similar function is accommodated in another auxiliary unit which thereby facilitate shared operation, and easy and fast maintenance or replacement of the operative component.

The method comprises acquiring 410 a first set of vibration data, the first set of vibration data being from a plurality of vibration sensors positioned at different locations about a wind turbine drivetrain when the wind turbine drivetrain is undergoing testing in a test rig; acquiring 420 a second set of vibration data, the second set of vibration data being from a plurality of vibration sensors positioned at different locations about the same or a similar wind turbine drivetrain when located in a wind turbine; acquiring 430 noise data including tonal noise produced by the wind turbine; identifying 440 a vibration sensor of interest using vibration data of the second set of vibration data and the noise data; determining 450, for the identified sensor, a first relationship between vibration data of the first set of vibration data and the second set of vibration data; and determining 460, for the identified vibration sensors, a second relationship between the first set of vibration data and tonal noise produced by a wind turbine based on the first relationship.

Abstract: An adaptive wind turbine generator (WTG) control system comprising a measurement system MS with sensors A1, A2, MC arranged to perform measurements of mechanical vibrations of one or more mechanical components of the WTG, at a plurality of operating conditions for the WTG. A storage unit SU stores, in a measurement database MD, measured data and corresponding operating condition OC data for the WTG. An operating condition manager OCM determines how to operate the WTG, including rotor speed PSC, according to a control algorithm in response to the data stored in the measurement database MD. Hereby, individual vibration measurements on critical components such as electric power generator and blades of the WTG can be taken into account in determining which rotor speed windows to avoid. This allow a more power efficient WTG, since a large safety margin around calculated or predetermined tabulated rotor speed windows can be avoided. Further, with a continuous update of the measurements, the control system can take into account variations in the vibration behavior of the components over time.
Abstract translation: 一种自适应风力涡轮发电机（WTG）控制系统，包括具有传感器A1，A2，MC的测量系统MS，其布置成在WTG的多个操作条件下执行WTG的一个或多个机械部件的机械振动的测量。 存储单元SU在测量数据库MD中存储用于WTG的测量数据和相应的操作条件OC数据。 操作状态管理器OCM根据存储在测量数据库MD中的数据根据控制算法确定如何操作WTG（包括转子速度PSC）。 因此，在确定要避免哪个转子速度窗口时，可以考虑对诸如发电机和WTG的叶片的关键部件进行单独的振动测量。 这允许更高功率的WTG，因为可以避免围绕计算的或预定的列表转子速度窗口的大的安全裕度。 此外，随着测量的不断更新，控制系统可以考虑组件随时间的振动行为的变化。

Abstract: A wind turbine (101) comprising a torque transmitting coupling (1) between a first rotatable part (2, 3) and a second rotatable part (2, 3) of the wind turbine (101), e.g. in the form of a hub (2) and a shaft (3), is disclosed. The torque transmitting coupling (1) comprises a form- fitted coupling and a compression means (5, 8, 9, 12, 13). The form-fitted coupling defines a plurality of drive flanks formed on the first rotatable part (2, 3) and a plurality of driven flanks formed on the second rotatable part (2, 3). The compression means (5, 8, 9, 12, 13) is arranged on an internal or external perimeter of the form-fitted coupling, and the compression means (5, 8, 9, 12, 13) provides a frictional coupling between the first rotatable part (2, 3) and the second rotatable part (2, 3). The torque transmitting coupling (1) is capable of locking up to six degrees of freedom between the first rotatable part (2, 3) and the second rotatable part (2, 3), while allowing the first rotatable part (2, 3) and the second rotatable part (2, 3) to be easily dissembled.
