Abstract

Methods for lubricating a pitch bearing connecting a blade and a hub of a wind turbine include determining that lubricating the pitch bearing is to be carried out. The method further includes determining a top limit for a thrust gradient, the thrust gradient being a derivative of thrust with respect to time. Further, the method includes determining a pitch rate for lubricating the pitch bearing based at least partially on the top limit for the thrust gradient, and pitching the wind turbine blade at the determined pitch rate for lubricating the pitch bearing such that the top limit for the thrust gradient is not exceeded.
