Abstract
A wind turbine includes a tower, a nacelle located adjacent a top of the tower, a rotor coupled to the nacelle, and a dynamic vibration damper coupled to the tower and configured to dampen vibrations induced in the tower in a torsional direction while negligibly effecting vibrations induced in the tower in bending directions. The dynamic vibration damper may be tuned to a resonant frequency of the wind turbine in the torsional direction. A method of retrofitting a wind turbine with a vibration damper is also disclosed.
