Abstract: 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.

Abstract: The present disclosure presents techniques to facilitate improving operation of an electrical system, which includes a bus structure that cascades multiple electrical devices. The bus structure includes a first outer conductive layer implemented as a positive layer; a second outer conductive layer implemented as a negative layer; a first intermediate conductive layer neighboring the first outer conductive layer; a second intermediate conductive layer neighboring the second outer conductive layer; and a third intermediate conductive layer neighboring the second intermediate conductive layer, in which the third intermediate conductive layer is implemented as an inter-device layer that facilitates electrically coupling at least two of the electrical devices in series. The first intermediate conductive layer is implemented as a negative layer and the second intermediate conductive layer is implemented as a positive layer to facilitate reducing stray inductance and/or increasing stray capacitance introduced in the electrical system during operation.

Abstract: 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.
