Title
(EN) METHOD FOR LOAD REDUCTION ON WIND TURBINE BLADE PITCH BEARINGS
(FR) PROCÉDÉ DE RÉDUCTION DE CHARGE SUR DES PALIERS DE PALE D'ÉOLIENNE
Abstract
(EN)
Method for load reduction on wind turbine blade pitch bearings It is described a method for adjusting a pitch angle (α) of a rotor blade (5) connected to a rotor (3) of a wind turbine (1), the method comprising: pitching the rotor blade (5) towards a target blade pitch angle, the manner of pitching depending on a load on a pitch bearing and/or an azimuthal position of the rotor.
(FR)
L'invention concerne un procédé de réduction de charge sur des paliers de pale d'éolienne, ainsi qu'un procédé de réglage d'un angle de pas (α) d'une pale de rotor (5) reliée à un rotor (3) d'une éolienne (1). Le procédé comprend les étapes consistant à: soumettre au tangage la pale de rotor (5) vers un angle de pas de pale cible, la manière de tangage dépendant d'une charge sur un palier de pas et/ou d'une position azimutale du rotor.
