Abstract[English]
A pitch controlled wind turbine has a tower, a nacelle mounted on the tower, a hub mounted rotatably on the nacelle, and at least three blades. The wind turbine includes at least three blade connecting members, each blade connecting member extending between neighbouring blades. The wind turbine has at least three pre-tension members, each connected to one of the blade connecting members and to the hub via a tensioning device, the tensioning device provides radial movement of the pre-tension member due to extension/retraction of the tensioning device, each pre-tension member thereby providing pre-tension in the blade connecting member to which it is connected. A de-icing system is coupled to one or more of the tensioning devices and configured to control the one or more tensioning devices to extend or retract to excite at least some of the wind turbine blades, blade connecting members and/or pre-tension members to displace ice therefrom.[French]
L'invention concerne une éolienne à pas variable qui comprend une tour, une nacelle montée sur la tour, un moyeu monté rotatif sur la nacelle, et au moins trois pales d'éolienne. L'éolienne comprend au moins trois éléments de liaison de pale dont chacun s'étend entre des pales voisines. L'éolienne comprend au moins trois éléments de pré-tension dont chacun est relié à l'un des éléments de liaison de pale et au moyeu par l'intermédiaire d'un dispositif de tension; le dispositif de tension fournit un mouvement radial de l'élément de pré-tension en raison de l'extension/rétraction du dispositif de tension; et chaque élément de pré-tension fournit ainsi une pré-tension dans l'élément de liaison de pale auquel il est relié. Un système de dégivrage est couplé à un ou plusieurs des dispositifs de tension et est configuré pour commander le ou les dispositifs de tension à s'étendre ou à se rétracter pour exciter au moins certaines des pales d'éolienne, des éléments de liaison de pale et/ou des éléments de pré-tension à déplacer la glace à partir de ceux-ci.
