    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.

    摘要： A wind turbine 100 includes a generator 132 and a control system 150. The control system 150 is configured to determine whether a predefined amount of turbulence will be induced to the wind turbine 100 by a wake zone created by a wind turbine upstream thereof. The control system 150 is also configured to adjust at least one constraint of the wind turbine to a first setting if the amount of turbulence is greater than the predefined amount, the constraint affecting power produced by the generator 132, and to adjust the constraint of the wind turbine 100 to a second setting if the amount of turbulence is not greater than the predefined amount.
