Abstract
A method for controlling operation of a generator for a wind turbine is disclosed. A measure for a rotational speed of the generator, and a measure for vibrations originating from gear tooth meshing of a gearbox of the wind turbine, at the rotational speed of the generator, and at least one amplitude of a harmonic in the gearbox vibrations is determined. An initial phase angle and an initial amplitude are selected, based on the rotational speed, on initial characteristics of the wind turbine, and on the at least one amplitude of the harmonic. An optimization process is performed to obtain an adjusted phase angle and an adjusted amplitude. A torque modulating signal for the generator, specifying the adjusted phase angle and the adjusted amplitude, is generated and injected into the generator. Information regarding residual vibrations at the minimised resultant vibration is derived.
