    摘要: A method for configuring blades 108 of a wind turbine 100 for low noise generation. The method includes providing at least one noise measuring device 209. The noise measuring device 209 is arranged and disposed in a position to measure noise of the blades 108 during rotation. The wind turbine 100 is configured to include a rotational trigger, the rotational trigger being arranged to provide a signal at a predetermined rotational position of the wind turbine blades 108. One or more of the blades 108 is configured with an aerodynamic modifying device. Noise level is measured with the noise measuring device 209 during wind turbine 100 operation. The noise produced by each of the blades 108 is determined. The blades 108 are configured in response to the noise determined for each of the blades 108. A method for measuring the noise level generated by an individual blade 108 and a wind turbine 100 configured for desired noise level are also disclosed.

    摘要: The invention relates to a method for monitoring wind energy plants, whereby an acoustic monitoring is particularly carried out. In order to further improve the maintenance, safety and economic viability of a wind energy plant it is desirable to monitor further parameters of the wind energy plant. The aim of the invention is thus to improve the monitoring of wind energy plants. A method for monitoring a wind energy plant thus comprises an arrangement whereby the sound arising in said region is recorded, by means of a sound pick-up, preferably in the interior of the wind energy plant where electrical or mechanical units are applied and the further arrangement therein of an optical recorder, for example a camera, the camera directed or capable of being directed towards the origin of said sounds.

    摘要: A method of operating a wind power plant comprising a plurality of wind turbines, the method comprising: identifying operation of the wind power plant in a reduced noise regime; determining that at least one of the wind turbines in the wind power plant is non-operational; and increasing the power output of one or more wind turbines in response to the determination. The invention also resides in a wind power plant control system, wherein a controller is configured to: identify when the power plant is in a reduced noise regime; determine that at least one of the wind turbines in the wind power plant is non-operational, and increase the power output of one or more of the wind turbines based on the results of the determination.

    摘要: The invention relates to a rotor blade (20) with a leading edge (23) and a trailing edge (24), wherein the rotor blade (20) is designed and configured for being exposed to a fluid flowing substantially from the leading edge (23) to the trailing edge (24) of the rotor blade (20), the rotor blade (20) comprises at least one sensor (31) for detecting flow characteristics of the fluid, and the rotor blade (20) further comprises at least one actuator (32) for producing an anti-noise signal. The sensor (31) and the actuator (32) are both arranged at the surface of the rotor blade (20), and the actuator (32) is arranged and prepared such that flow-induced edge noise of the rotor blade (20), which is generated by the fluid, is at least partly cancelled out by the anti-noise signal. The invention furthermore relates to a wind turbine comprising at least one such rotor blade (20).

    摘要: A wind turbine having at least one trailing edge control surface on at least one rotor blade is operated in a first mode, in which a rotor blade angle of attack and a trailing edge control surface deflection are set according to one or more wind turbine control parameters. The turbine is selectively operated in a second, noise reduced, mode, in which for a given set of wind turbine control parameters, the trailing edge control surface deflection is increased towards the pressure side and the rotor blade angle of attack is decreased with respect to the first mode. In the second mode, for a given set of control parameters, the loading on the blade is on average closer to a hub than in the first operating mode.
