METHOD AND APPARATUS FOR DAMPING VIBRATIONS IN A WIND ENERGY SYSTEM

摘要

A method for influencing vibrations in an operating wind energy system is described. The wind energy system includes a tower including a tower top and an intermediate tower area; and a rotor and a generator arranged at the tower top. The method includes determining the vibration of the intermediate tower area of the wind energy system; and influencing the vibrations of the intermediate tower area dependent on the determined vibrations of the intermediate tower area by adjusting an operating parameter of the wind energy system.
