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 wind turbine blades. The wind turbine has at least three pretension members, each being connected to one of the blade connecting members and to the hub via a tensioning device, the tensioning device provides radial movement of a radially inward end of the pre-tension member with respect to an axis of rotation of the hub 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. An anti-icing system and/or a de-icing system is provided for protecting one or more of the blade connecting members, the pre-tension members, the connection points, or the tensioning devices.[French]
L'invention concerne une éolienne à pas variable qui comprend un mât, une nacelle montée sur le mât, un moyeu monté rotatif sur la nacelle, et au moins trois pales. L'éolienne comprend au moins trois éléments de liaison de pale dont chacun s'étend entre des pales d'éolienne voisines. L'éolienne comprend également 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 mise en tension. Ledit dispositif de mise en tension donne un mouvement radial à une extrémité située radialement vers l'intérieur de l'élément de pré-tension par rapport à l'axe de rotation du moyeu en raison de l'extension ou de la rétraction du dispositif de mise en tension. Chaque élément de pré-tension applique ainsi une pré-tension à l'élément de liaison de pale auquel il est relié. Un système anti-givrage et/ou un système de dégivrage sont utilisés pour protéger un ou plusieurs des éléments de liaison de pale, des éléments de pré-tension, des points de liaison ou des dispositifs de mise en tension.
