Abstract
A method for damping torsional vibrations in a power generation plant that includes a drive train, a rotor fitted at a rotor-side end of the drive train, and a generator driven via the drive train and fitted at a generator-side end of the drive train includes determining an angular difference between a first point and a second point on the drive train over time. The method further includes damping torsional vibrations in the drive train on the basis of the time profile of the determined angular difference by correspondingly presetting a load torque of the generator and a drive torque of the rotor.
