Abstract: The invention relates to a wind turbine generator with rotor blades being pitchably mounted, and a hub for connecting the rotor blades with the rotation shaft. The hub further comprises a plurality of radially extending support structures, a plurality of inclined support beams, one inclined support beam for each rotor blade, and/or at least a first peripheral support rod positioned in an exterior position on the hub, said first peripheral support rod connecting two of said radially extending support structures. The rotation axis for each pitchable rotor blade has a radial offset relative to the rotation shaft. The invention is thereby advantageous for obtaining a wind turbine where the resonances of the rotor blades may be controlled, i.e. shifted and/or reduced, by designing and dimensioning the plurality of inclined support beams and/or the first peripheral support rod accordingly.

Abstract: 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.

Abstract: A method for controlling noise generated by a wind farm (1) with a plurality of wind turbines (2) is disclosed. A noise propagation model (7) related to noise propagation across the wind farm (1) and in the vicinity of the wind farm (1), under various operating conditions, is provided. For each wind turbine (2), a wind turbine model (8) is provided. A noise level at a predefined evaluation position is predicted, based on the noise propagation model (7), the wind turbine models (8) and information regarding the current operating conditions. In the case that the predicted noise level exceeds a predefined threshold noise value, one or more wind turbines (2) are selected using the noise propagation model (7) and the wind turbine models (8), and by performing an optimisation process with the predefined threshold noise value at the predefined evaluation position as a constraint, the noise generation and the power production of the wind turbines (2) as optimisation variables, and the total power production of the wind farm (1) as an optimisation target, thereby reducing the predicted noise level at the predefined evaluation position to a level below the predefined threshold noise value while maximising the total power production of the wind farm (1).
