The present invention relates to a wind turbine assembly system which proposes an alternative to conventional cranes, having a main lifting structure configured to withstand the load of at least one tower section or at least one wind turbine component, and at least one secondary lifting structure configured to perform the lifting of the main lifting structure with respect to the wind turbine tower, in addition relating to a wind turbine assembly method according to the previous system, as well as the wind turbine assembled with the previous method.

Wind turbine assembly system and associated method

A wind turbine tower that may be assembled fast, including a nacelle and a rotor, the tower comprising at least two stackable annular sections made of concrete connected through a main connecting arrangement adapted to withstand loads induced by the wind turbine rotor, and an auxiliary connector.

Wind turbine assembling method and wind turbine assembled according to said method

The wind turbine has a tower; a nacelle; and a hub comprising a hub connection flange for being detachably connected to a blade connection flange of a rotor blade. The method comprises the next steps: fixing a first positioning element in the nacelle or in the top of the tower; fixing a second positioning element to the blade in a root blade area; lifting the blade to the vicinity of the hub connection flange by means of lifting means; putting into contact the first and the second positioning elements; providing an accurate position of the blade connection flange, prior to the connection to the hub connection flange, by cooperation of the first and second positioning elements; and providing, when the first and the second positioning elements cooperate, a trajectory of the blade which is parallel to the axis of a hub connection hole, disposed in the hub connection flange, the provision of the trajectory being carried out by means of a guided element joined to either the first positioning element, the second positioning element, or both.

Method for assembling a blade of a wind turbine

A method and system is provided for assembling or disassembling a blade of a wind turbine. The wind turbine includes a tower resting on a base, a rotor including at least one rotor blade having a blade connection flange and a nacelle mounted atop the tower, a hub rotatably connected to the nacelle and including a hub connection flange adapted to be detachably connected to a blade connection flange of a rotor blade. Thy wind turbine further includes a first positioning element adapted to be attached to the nacelle or to the tower in a top area and a second positioning element adapted to be joined to the blade in a root blade area, where the first and second positioning elements are configured to cooperate to provide an accurate position of the blade connection flange prior to connection to the hub connection flange.
