Abstract
The disclosure relates to controlling blade pitch in a wind turbine that has a plurality of rotor blades and a hydraulic pitch system for adjusting a pitch of each of the rotor blades. The disclosure describes a method comprising obtaining a measurement indicative of a current level of hydraulic pressure available in the hydraulic pitch system, and determining, based on the obtained measurement, an adaptive pitch reference rate indicative of a rate at which the pitch of the rotor blades is to be adjusted by the hydraulic system. The method includes controlling the hydraulic pitch system to adjust the pitch of the rotor blades in accordance with the determined adaptive pitch reference rate.
