Title
(EN) METHOD FOR OPERATING AND/OR MAINTAINING A WIND TURBINE
(FR) PROCÉDÉ PERMETTANT DE FAIRE FONCTIONNER ET/OU D'ENTRETENIR UNE ÉOLIENNE
Abstract
(EN)
The invention relates to a method for operating and/or maintaining a wind turbine, wherein the wind turbine comprises a hub element (1) at which a number of blades (2) is mounted, wherein a slewing bearing (3) is arranged between the hub element (1) and a blade (2) for adjusting the blade position relatively to the hub element (1), wherein a pitch drive (4) is provided for adjusting the blade position, wherein first connection means (5) are provided for fixing the blade (2) to a first ring (6) of the slewing bearing (3) and wherein second connection means (7) are provided for fixing the hub element (1) to a second ring (8) of the slewing bearing (3). To facilitate maintaining of the wind turbine the invention is characterized in that the method comprises the steps of: a) Mounting third connection means (9) for establishing a firm connection between the hub element (1) and a blade (2); b) Dismounting at least the first connection means (5); c) Turning the first ring (6) of the slewing bearing (3) around a predetermined angle by means of the pitch drive (4) relative to the blade (2); d) Mounting the first connection means (5) between the blade (2) and the first ring (6) of the slewing bearing (3); e) Dismounting the third connection means (9) between the hub element (1) and the blade (2).
(FR)
L'invention concerne un procédé permettant de faire fonctionner et/ou d'entretenir une éolienne, l'éolienne comprenant un élément moyeu (1) sur lequel est monté un certain nombre de pales (2). Un palier d'orientation (3) est agencé entre l'élément moyen (1) et une pale (2) et sert à ajuster la position de la pale par rapport à l'élément moyeu (1), une commande de pas (4) est conçue pour ajuster la position de la pale, de premiers moyens de raccordement (5) sont conçus pour la fixation de la pale (2) à une première bague (6) du palier d'orientation (3) et de deuxièmes moyens de raccordement (7) sont conçus pour la fixation de l'élément moyeu (1) à une deuxième bague (8) du palier d'orientation (5). Visant à faciliter l'entretien de l'éolienne, le procédé selon l'invention comprend les étapes suivantes,: a) montage de troisièmes moyens de raccordement (9) permettant de créer un raccordement fixe entre l'élément moyeu (1) et une pale (2) ; b) démontage d'au moins les premiers moyens de raccordement (5) ; c) rotation de la première bague (9) du palier d'orientation (3) au moyen de la commande de pas (4) selon un angle prédéterminé par rapport à la pale (2) ; d) montage des premiers moyens de raccordement (5) entre la pale (2) et la première bague (6) du palier d'orientation (3) ; e) démontage des troisièmes moyens de raccordement (9) entre l'élément moyeu (1) et la pale (2).
