Abstract[English]
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.[French]
L'invention concerne la commande de pas de pale dans une éolienne qui comporte une pluralité de pales de rotor et un système de pas hydraulique pour ajuster un pas de chacune des pales de rotor. L'invention concerne un procédé comprenant l'obtention d'une mesure indicative d'un niveau de courant de pression hydraulique disponible dans le système de pas hydraulique, et la détermination, sur la base de la mesure obtenue, d'un taux de référence de pas adaptatif indicatif d'une vitesse à laquelle le pas des pales de rotor doit être ajusté par le système hydraulique. Le procédé comprend la commande du système de pas hydraulique pour ajuster le pas des pales de rotor en fonction du taux de référence de pas adaptatif déterminé.
