1. A method of correcting a measurement value of least one wind characteristic, related to a wind turbine having a rotor with plural rotor blades, at least one having an adaptable flow regulating device installed, the method comprising:
measuring a value of the wind characteristic;
obtaining state information of the adaptable flow regulating device; and
determining a corrected value of the wind characteristic based on the measured value of the wind characteristic and the state information of the adaptable flow regulating device;
wherein the wind characteristic includes wind direction, and
wherein a value of wind direction is used as a reliable value when setting up a correction function, or wherein a derived value of the wind direction, as derived by performing a hill climbing algorithm in which a nacelle orientation is changed until most power output is obtained, is used as a reliable value when setting up a correction function.
