VORRICHTUNG ZUR AKTIVEN DÄMPFUNG EINES TRIEBSTRANGS BEI EINER WINDENERGIEANLAGE

摘要

The method involves detecting the actual value of the generator revolution rate (36) and amplifying it via a vibrational delay element (40) with a natural vibration frequency lower than the lowest natural frequency of the drive train and applying the difference between the actual and amplified (42) revolution rate values as the control error to a regulator (48) that determines a correction torque (55) for the generator controller.
