Abstract
A method for the oscillation damping of a drive train in a wind turbine is proposed. The drive train connects a rotor to a generator. Parameter values representing an oscillation of the drive train are calculated and, on the basis of the calculated parameter values, damping forces which counteract the oscillation of the drive train are exerted in a controlled manner on the drive train by a braking device.
