Abstract: A method for the operation of a wind energy plant, with a synchronous generator, a superimposition gearbox, which is connected between rotor shaft and generator shaft, and a drive unit, wherein before connecting the synchronous generator to the electric grid, the drive unit drives the synchronous generator until the same has reached its rated rotational speed.

Abstract: A method for the operation of a wind energy plant, with a synchronous generator and a superimposition gearbox, which is connected between rotor and generator, and the gear ratio of which is adjusted by a control unit, characterised in that a mode of operation is provided in which the generator is connected to the electric grid, and the generator shaft is uncoupled from the rotor shaft via the superimposition gearbox.

Abstract: Method for the operation of a wind power plant with controllable effective power, wherein an idle power interval defined by a minimum idle power and a maximum idle power is assigned to each value of the effective power and the actual idle power can be controlled within this interval, characterized in that the effective power is reduced when a target idle power lies outside of the idle power interval assigned to the current effective power.

Abstract: A method for the active damping of a drive train in wind energy plant, with the following steps: the actual value of the generator rotational speed is acquired and amplified via an oscillatory delay element, the oscillatory delay element has a predetermined natural oscillation frequency (?E), which is smaller than the smallest natural frequency of the drive train, and a difference between the actual value of the rotational speed and the amplified value for the rotational speed is connected to a controller as actuating variable, which determines a correction moment for a generator control.
