AI Technical Summary
Wind turbines generate structure-borne vibrations and associated noise, particularly from gear tooth meshing in the gearbox, which can exceed allowable noise limits and disturb neighbors or animal life.
A method for controlling generator operation by generating a torque modulating signal based on rotational speed and gearbox vibrations, optimizing phase angle and amplitude to minimize resultant vibrations and noise, and deriving information on residual vibrations for monitoring.
Reduces noise emissions from wind turbines by minimizing vibrations from gear tooth meshing, while providing valuable information for monitoring the condition and health of the wind turbine.
