The invention discloses an individual pitch control method and device for inhibiting loading of a wind generation set. The method comprises the steps of generating a unified pitch angle used for limiting the output power of the wind generation set at the high wind speed according to rotating speeds of impellers; generating first deviation pitch angles used for inhibiting balanced loading of blades according to blade root loading measured values obtained after phase compensation; generating second deviation pitch angles used for inhibiting unbalanced loading of hubs according to the blade root loading measured values; and calculating a final pitch angle according to the unified pitch angle, the first deviation pitch angles and the second deviation pitch angles. According to the individual pitch control method and device for inhibiting loading of the wind generation set, the final pitch angle is calculated according to the unified pitch angle, the first deviation pitch angles and the second deviation pitch angles; meanwhile, balanced loading and unbalanced loading of the wind generation set are inhibited; and thus reliability of the wind generation set is improved, and the service life of the wind generation set is prolonged.
