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 pre- tension members, each being connected to one of the blade connecting members and to the hub via a tensioning device. The tensioning device is configured to provide pre- tension in the blade connecting member to which it is connected. An anti-icing system and/or a de-icing system is provided that includes one or more heating elements for protecting one or more of the blades. One or more electrical power source paths for the anti-icing system or de-icing system are routed between the hub and the heating element along at least one of the blade connecting members and pre-tension members.[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 d'éolienne 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 est conçu pour fournir une pré-tension dans l'élément de liaison de pale auquel il est relié. L'invention concerne un système anti-givrage et/ou un système de dégivrage qui comprend un ou plusieurs éléments chauffants pour protéger une ou plusieurs des pales. Un ou plusieurs trajets de source d'alimentation électrique pour le système anti-givrage ou le système de dégivrage sont acheminés entre le moyeu et l'élément chauffant le long d'au moins l'un des éléments de liaison de pale et des éléments de pré-tension.
