Title (EN) DETERMINING A WIND TURBINE TOWER INCLINATION ANGLE
(FR) DÉTERMINATION D'UN ANGLE D'INCLINAISON DE TOUR D'ÉOLIENNE
Abstract:
(EN) Determining a wind turbine tower inclination angle It is described a method of determining an inclination angle (Inc) of a wind turbine tower (103) at which a nacelle (105) is mounted, the method comprising: measuring plural acceleration values (Ay) of an acceleration of the nacelle (105) in a predetermined direction (113) relative to the nacelle for plural yawing positions (Nac_pos) of the nacelle (105); deriving the inclination angle based on the plural acceleration values.
(FR) L'invention concerne un procédé de détermination d'un angle d'inclinaison (Inc) d'une tour d'éolienne (103) au niveau de laquelle est montée une nacelle (105). Le procédé consiste à : mesurer plusieurs valeurs d'accélération (Ay) d'une accélération de la nacelle (105) dans une direction prédéterminée (113) par rapport à la nacelle pour plusieurs positions de lacet (Nac_pos) de celle-ci; déduire l'angle d'inclinaison sur la base des multiples valeurs d'accélération.
