Abstract:
The invention relates to a wind turbine (1) with a pitch drive (3) for rotor blade adjustment, whereby the drive regulation (31) of the pitch drive (3) responds to disturbance torques (SM) during operation of the wind turbine (1) so as to have an equalizing effect, and the invention also relates to a corresponding method for the drive regulation (31). For this purpose, the wind turbine (1) comprises at least one load sensor (4) that is arranged in the vicinity of the pitch drive (3) in order to determine the mechanical load being exerted on the drive mechanism (A) due to a disturbance torque (SM), and said load sensor is also provided in order to emit a sensor signal (SS) corresponding to the mechanical load, and the drive regulation (31) comprises a feedback means (311) for the feedback (R) of an evaluated torque signal (BDS) on the basis of the sensor signal (SS). In this manner, a wind turbine with rotor blade adjustment can be provided that has a prolonged service life, a greater reliability and an improved availability.
