Vibration damping system and method for variable speed wind turbines

摘要

A vibration damping technique for a wind turbine sysetm (10) is described. The wind turbine system (10) includes a vibration damper (62), which provides a variable signal (68) to control torque produced by a generator (50) of the wind turbine system (10). The variable signal (68) is based on generator speed and has a first local peak value based on a resonant frequency of tower side-to-side oscillation.
