    Abstract: The invention refers to a wind turbine blade formed by two shell halves, wherein one shell half has a first pair of metallic sheets layered, on the outer surface of the shell half, and wherein each of the metallic sheets has been partially embedded within the shell half during the resin infusion process. A first heating mat made of an electrically conductive material is layered on resin-free parts of the metallic sheets, and is also embedded within the shell half so that the first heating mat is electrically in contact with the resin-free parts of the metallic sheets. The invention also refers to a method for manufacturing a wind turbine blade, integrating an Ice Protection System, the method comprising the steps of manufacturing first and second shell halves by means of a resin infusion process, and integrating an Ice Protection System in the same resin infusion process for manufacturing the shell halves.

    Abstract: The invention describes a method of controlling a wind turbine (2), which method comprises the steps of determining a noise budget (Nbudget) for each of a plurality of operating modes (M; M1, ..., M7) of the wind turbine (2); establishing the current operating mode (M; M1, ..., M7) of the wind turbine (2); and limiting the motor speeds (ωA1 - ωAn) of each of a plurality of motor-driven auxiliary devices (A1, ..., An) of the wind turbine (2) such that the noise budget (Nbudget) is not exceeded. The invention further describes a wind turbine (2) comprising a control arrangement (1) configured to operate the wind turbine (2) in any of a plurality of operating modes (M; M1, ..., M7) and to limit the motor speeds (ωA1 - ωAn) of each of the plurality of motor-driven auxiliary devices (A1, ..., An) such that a previously established noise budget (Nbudget) for the current operating mode (M; M1, ..., M7)is not exceeded.

    Abstract: The invention refers to a wind turbine blade integrating a lightning protection system. The wind turbine blade comprises one spar cap formed by a plurality of carbon plates stacked together. The wind turbine blade comprises a first down-conductor placed alongside the tip region of the spar cap, and a second down-conductor placed alongside the root region of the spar cap. The first down-conductor extends from the spar cap's tip end towards the spar cap's mid region, and terminates at a first down-conductor's end located adjacent a first region of the spar cap which extends from a cross-sectional area of the spar cap which area is equal or higher than 75% of the maximum cross-sectional area of the spar cap, being that area the one closest to the spar cap's tip end, to a cross-sectional area of the spar cap which area is 100% of the cross-sectional area of the spar cap, being that 100% of the cross-sectional area the one closest to the spar cap's root end.
