摘要: 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.

摘要: 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.

摘要: The invention refers to a control method for power converter, that assures operation under Zero Voltage Switching (ZVS) condition in a broad power range in a reliable manner, and which is easy to implement. The control method for operating a DC-DC isolated converter, comprises operating the converter by modifying the switching frequency (fsw) and the phase shift (ϕ) of the converter, to operate the converter under Zero Voltage Switching condition. The invention is especially applicable to multi-port converters, that is, to converters having three or more converters coupled to a common multi-windings transformer.

摘要: The present invention relates to a root portion (12) for a wind turbine blade (10), comprising: an inner wall (14), an outer wall (15), a filler (16) between the inner wall (14) and the outer wall (15), an inner volume (13) defined by the inner wall (14), mounting inserts (17) for mounting the root portion (12) to a hub (51) of a wind turbine (50), wherein the mounting inserts (17) are supported by the filler (16) and extend in a longitudinal direction (18) of the root portion (12), and a transversal holding arrangement (19) extending in a transversal direction (20) from the inner wall (14) and/or the outer wall (15) into the filler (16), wherein the transversal holding arrangement (19) is connected to at least one mounting insert (17) for holding the mounting insert (17) in the root portion (12) during operation of the wind turbine blade (10). The invention further relates to a wind turbine blade (10) with the root portion (12), a method of producing the root portion (12) and a method for modifying a root portion.
