METHOD AND DEVICE FOR DAMPING TORSIONAL OSCILLATIONS

摘要

The invention relates to a method for damping torsional oscillations in a power production plant (100) having a drive train (2-5), a rotor (1) fitted to a rotor-side end (1') of the drive train (2-5) and a generator (6) driven via the drive train (2-5) and fitted to a generator-side end (6') of the drive train (2-5). By using at least one angular position (fG) of the drive train (2-5) at the generator-side end (6') thereof, a torsional moment (MT) acting on the drive train (2-5) is determined and used to control the generator (6).
