摘要： A wind turbine 30 comprising: a rotor 36 having a plurality of blades 38; and a controller 100. The controller 100 is arranged to independently control each of the plurality of blades 38 and/or one or more components of each blade 38 in order to increase a driving moment of each blade 38 independently of other of the blades 38 when speed of wind acting on the wind turbine 30 is below rated. The controller 100 is also additionally or alternatively arranged to independently control each of the plurality of blades 38 and/or one or more components of each blade 38 independently of other of the blades 38 when wind force acting on the blades 38 is above cut-out in order to reduce a mechanical load experienced by at least a part of the wind turbine 30.

摘要： A wind turbine comprising a number of blades including at least a first wind turbine blade extending substantially radially from a hub on a main shaft having a substantially horizontal centre axis is disclosed. The blades together with the hub constituting a rotor with a rotor plane, and which can be put into rotation by wind, and each blade having an innermost part comprising a root section of the blade and an outermost part comprising a tip section of the blade. The wind turbine comprises an optical measurement system comprising a light source, such as a laser, an optical transmitter part, an optical receiver part, and a signal processor. The light source is optically coupled to the optical transmitter part. The optical transmitter part comprises an emission point and is adapted for emitting light in a probing direction from said emission point. The optical receiver part comprises a receiving point and a detector, wherein the optical receiver part is adapted for receiving a reflected part of light from a probing region along the probing direction at the receiving point and directing said reflected part of light to the detector so as to generate a signal from the detector based on the received, reflected light. The signal processor is adapted to determine at least a first velocity component of the inflow from the signal generated by the optical receiver part. The emission point of the optical transmitter part is located in the first blade at a first radial distance from the centre axis, and the receiving point of the optical transmitter part is located in the first blade at a second radial distance from the centre axis.

It comprises a leading edge (109), a trailing edge (111) and a chord line (101) between the leading edge (109) and the trailing edge (111). The flap arrangement (20) comprises a support portion (21) and a flap portion (22) which is passively moveable with respect to an angle (²) between a surface normal (34) of a surface (41) of the flap portion (22) and the chord line (101). The support portion (21) and the flap portion (22) are positioned relatively to each other such that the support portion (21) provides a limit to the movement of the flap portion (22).
