Abstract

See full text

A method of identifying a fault in a system of gears in a wind turbine is provided. The method determines two or more centre harmonic frequency amplitudes according to vibrations of the system of gears and determines a plurality of sideband amplitudes of each of the centre harmonic frequency amplitudes. Further, the method sums the centre harmonic frequency amplitudes to calculate a total centre harmonic frequency amplitude and sums each of the sideband amplitudes of the centre harmonic frequency amplitudes to calculate a total sideband amplitude. The method then determines a value indicative of damage incurred by the system of gears based upon the first centre harmonic frequency amplitude and the average sideband amplitude.
