Abstract: A method of masking wind turbine noise from a wind turbine. Masking noise is generated to produce resultant noise with a modulation depth which is less than a modulation depth of the wind turbine noise and an average level which is greater than an average level of the wind turbine noise. The masking noise is either un-modulated masking noise with a substantially constant level, or amplitude-modulated masking noise which is phase-shifted relative to the wind turbine noise and has a modulation depth which is less than the modulation depth of the wind turbine noise.

Abstract: A detuner system for a wind turbine includes a drive train component having a natural frequency. The drive train component is configured to rotate about an axis of rotation at a range of different speeds. The detuner system includes a controller for selectively interacting with the drive train component and cause a step change in the natural frequency of the drive train component at a first threshold of the rotational speed range, and cause a step change in the natural frequency of the drive train component at a second threshold of the rotational speed range different to the first threshold.

Abstract: The present invention relates to a wind turbine generator with a hub that has a plurality of radially extending support structures, one radially extending support structure for each rotor blade, and a plurality of inclined support beams, one inclined support beam for each rotor blade, and/or 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 inclined support beams, and/or the first peripheral support rod have an airfoil shape providing aerodynamic lift upon wind engagement. This is advantageous for obtaining a wind turbine where the rotor blades resonances are controlled by designing and dimensioning the plurality of inclined support beams and the first peripheral support rod accordingly. At the same time the volume of the hub is utilized for increasing the aerodynamic lift while still facilitating a relatively strong structure of the hub.

Abstract: A wind turbine blade assembly has a main blade portion and a blade tip module mounted to a tip end of the main blade portion. The wind turbine blade assembly has at least one blade extension portion having an aerofoil section, and which is attached to the main blade portion of the wind turbine blade assembly after the main blade portion has been manufactured, either during production or as a retro-fit. The blade extension portion increases the length of the turbine blade assembly and is selected from a number of possible blade extension portion lengths to obtain a desired wind turbine blade length. This enables the length of each blade to be optimised.

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.
