Abstract: A wind turbine tower wall having an orifice for accessing the interior of the tower, and an outer surface defined by generatrices; and a reinforcement frame joined to the tower in the orifice zone, and comprising least two parts joined one to each other. Each part has a mid-plane that is parallel to at least one generatrix, the mid-planes of at least one pair of adjacent parts forming an angle other than 180° therebetween. It enables the obtention of a frame more conformed to the curvature of the tower, combining savings in the material of said frame, greater optimization of the resistance of the tower and reduced stress concentration.

Abstract: Wind turbine blade having at least one longitudinal hollow element that defines an aerodynamic outer surface and an inner cavity having an inner surface. The blade also comprises at least one spar (1), disposed in the inner cavity and bonded to the inner surface by at least two bonding surfaces (13) located on bonding surfaces (2) of the spar (1). The spar (1) comprises, on at least one bonding zone (2), at least three fibre fabric layers (3) and at least one central core (4) and at least one lateral core (5) disposed between the at least three fibre fabric layers (3). This makes it possible to increase the resistance to shear stresses in the adhesive bond of the spar (1) to the inner surface of the longitudinal hollow element and decrease the required amount of adhesive.

Abstract: Wind turbine foundation (1) comprising an annular base plate (2) comprising a supporting surface (3) and defining a central hollow (4) by at least an inner lateral surface (6). The central hollow (4) further comprises a lower surface (5) arranged at a level lower than a level of the supporting surface (3). In particular, the central hollow (4) has a dimension (D), defined by the distance between at least an inner upper surface (10) and the lower surface (5), established such as to allocate additional equipment between both surfaces. A method of constructing said wind turbine foundation (1) is also described.

Abstract: The present invention relates to a wind turbine rotor balancing method which compensates imbalances between the centers of gravity of the wind turbine blades, in both magnitude and position along said blades, so that the amount of mass needed to carry out this balancing method is minimized, while reducing the loads and vibrations associated with a position of the center of gravity of the rotor not aligned with the axis of rotation thereof, wherein the invention further relates to the wind turbine rotor balancing system and the wind turbine balanced with the above method.
