FIELD: power industry.
SUBSTANCE: method for operation of a wind turbine (1) with a rotor (6) from rotor blades (8) with a substantially horizontal axis of rotation for electrical energy generation from wind energy, the wind turbine (1) is oriented so that the azimuthal position of the wind turbine (1) deviates from wind orientation (16) for azimuth adjusting angle and/or installation angle of the rotor blades (8) relative to the rotation cycle is being adjusted so that the variable loads caused by a wind profile (16) in height are being reduced. The wind turbine (1) runs in the profile operating point deviating from a normal operating point, wherein a normal operating point, in particular, in the partial load range has a normal blade installation angle calculated for the prevailing wind (16), but excluding the wind profile, and provides proper orientation of the azimuthal position of the wind (16), the profile operating point provides a profile azimuthal position deviating from the normal orientation at an angle of azimuth adjustment, and has a profile blade installation angle deviating from the normal blade installation angle on the blade adjustment angle between the azimuth adjustment angle and the blade adjustment angle perform weighing so that the azimuth adjusting angle value on azimuth weighting factor is greater than the blade adjusting angle value or the blade angle adjustment value on a blade weighting factor is greater than the azimuth adjustment angle value. Azimuth weighting factor and blade weighting factor, respectively, are greater than 1.2, preferably greater than 1.5, and in particular greater than 2.
EFFECT: reduction of height loads, reduction of sound emissions, increase in productivity.
