The invention relates to a wind turbine () with a pitch drive () for rotor blade adjustment, whereby the drive regulation () of the pitch drive () responds to disturbance torques (SM) during operation of the wind turbine () so as to have an equalizing effect, and the invention also relates to a corresponding method for the drive regulation (). For this purpose, the wind turbine () comprises at least one load sensor () that is arranged in the vicinity of the pitch drive () 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 () comprises a feedback means () 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.

An emergency power supply device is provided to supply emergency power to a direct voltage circuit. The direct voltage circuit has a first potential tap and a second potential tap, comprising an energy storage unit. The energy storage unit has a plus pole and a minus pole, and one of the poles is connected to the first potential tap via a first connection. The other pole is connected to the second potential tap via a second connection. At least one of the connections has a directional electric current meter and at least one of the connections has an interrupter. The directional electric current meter can measure a flow of charging current. The interrupter can prevent a flow of charging current, and the interrupter can be controlled as a function of the flow of charging current that has been measured.
