Method for attenuating the oscillation of a power train in a wind turbine, wind turbine and use of a braking device

摘要

The method involves determining parameter values representing vibration of drive train (22) of rotor (14) with a generator (45). The drain train is controlled using a brake device (43) based on determined parameter values, such that damping forces are exerted on drive train against vibration of drive train. An independent claim is included for wind turbine.
