A wind energy installation includes a pylon, a pivotable machine housing arranged on the pylon, a rotor configured to rotate on an end face of the machine housing and to drive a generator for production of electrical power, measurement devices for measurement of wind speed and direction and of an electromechanical quantity, a controller for the pivoting device, and a calibration module for the controller that comprises an efficiency measure element configured to calculate an efficiency measure for the production of the electromechanical quantity via the wind speed and an evaluation device. The evaluation device includes a classifier with outputs for positive and negative wind directions and calculation elements for determining mean values of the outputs and a comparator element which determines the difference between the mean values and outputs a calibration signal corresponding to the difference to the controller for the pivoting device. |
