Abstract
A method for detecting fatigue state of cog belt of wind power generator set is provided, including acquiring pitch angles satisfying preset condition, acquiring signal characteristic values corresponding to the pitch angles, selects from the pitch angles according to acquisition timing sequence of signal characteristic values pitch angles at which signal characteristic value changes, performing characteristic statistics on selected pitch angles to acquire characteristic statistic value and determining whether the cog belt is in fatigue state by comparing characteristic statistic value with predetermined threshold.
