ABSTRACT:
This relates to a wind power installation comprising a pylon (tower) and a rotor arranged on the pylon and having at least one individually adjustable rotor blade. The wind power installation further comprises a device to detect the wind direction, a device to detect the azimuthal position and/or a device to detect the deviation from vertical of the pylon (tower). In one embodiment, a control unit is coupled to the rotor blade to adjust an angle of incidence of the at least one adjustable rotor blade using information which is representative of (i) the wind direction, (ii) the azimuthal position of the rotor, and (iii) the deviation from vertical of the pylon. The rotor blade may be adjusted in dependence on a deviation between the ascertained wind direction and the detected azimuthal position.
