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 (omegaE), 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.
