A system and method are provided for reducing vibrations and loads in one or more rotor blades on a rotor hub of a wind turbine when the rotor hub is in a locked or idling condition. A mass damper is attached at a fixed location on one or more of the rotor blades and is maintained on the rotor blades during the locked or idling condition of the rotor hub. The mass damper includes a movable mass component that is responsive to changes in the vibrations or oscillations induced in the rotor blades during the locked or idling condition of the rotor hub.

System and method for use of a tunable mechanical mass damper to reduce vibrations in wind turbine blades in a locked or idling condition of the rotor hub

A system and method include with a mass damper for reducing vibrations in a structure or machine. The mass damper includes a frame that is movable linearly along a base, which includes a track gear. A flywheel is in geared engagement with the track gear so as to be rotationally driven as the frame moves linearly relative to the base. A rotation damper is mounted on the frame and is geared engagement with the flywheel, the rotation damper producing a counter-torque against rotation of the flywheel that is proportional to a rotational velocity of the flywheel. The rotation damper has an electrical characteristic that is automatically adjusted to change the counter-torque and tune the mass damper.

Automatically tunable mass damper

A system and method are provided for reducing vibrations and loads in one or more rotor blades on a rotor hub of a wind turbine when the rotor hub is in a locked or idling condition. An electronically tunable spring mass damper is attached to a fixed location on one or more of the rotor blades. The spring mass damper is maintained on the rotor blades during the locked or idling condition of the rotor hub. The method includes sensing movement of the mass component resulting from the vibrations induced in the blade. Based on the sensed movement of the mass component, the spring mass damper is automatically tuned to the amplitude of the vibrations by operating the electric machine as a generator in a virtual damper mode and/or tuned to the frequency of the vibrations by operating the electrical machine as a motor-generator in a virtual spring mode.
