摘要： Wind Turbine Blade (12) Leading Edge (24, 30, 88) Protection Method In a first aspect of the invention there is provided a method of applying an erosion shield (22) to a leading edge region (30) of a wind turbine blade (12). The method comprises providing a wind turbine blade (12) comprising a blade shell (26) having an aerodynamic profile and defining a leading edge region (30); providing an erosion shield (22) made of a polymer material, the erosion shield (22) having an inner surface (36) to be bonded to the leading edge region (30) of the blade shell (26), and an outer surface (38, 84, 98) to be exposed in use; activating (44) the inner surface (36) of the erosion shield (22), and cleaning (42) the inner surface (36) of the erosion shield (22) using a solvent. The method further comprises applying a layer of wet adhesive (66, 68, 72A) to the inner surface (36) of the erosion shield (22); applying a layer of wet adhesive (66, 68, 72A) to the leading edge region (30) of the blade shell (26); arranging the erosion shield (22) against the leading edge region (30) of the blade shell (26) such that wet-to-wet adhesive (66, 68, 72A, 72, 96) contact is established between the inner surface (36) of the erosion shield (22) and the blade shell (26), and curing the adhesive (66, 68, 72A, 72, 96) to bond the erosion shield (22) to the leading edge region (30) of the blade shell (26).

The method comprises: providing a male mould (28) extending longitudinally in a spanwise direction between an inboard end (30) and an outboard end (32) and extending transversely in a chordwise direction between a leading edge (34) and a trailing edge (36), the male mould (28) defining a male mould surface (38) of convex curvature in the chordwise direction; providing a root plate (48) having one or more root inserts (50) projecting therefrom, the or each root insert (50) being arranged along an arcuate path; arranging one or more inner fibrous layers (40) on the male mould surface (38); arranging the root plate (48) at the inboard end (30,) of the male mould (28) such that the or each root insert (50) overlays an inner fibrous layer at the root end of the mould (28). The method further comprises arranging one or more outer fibrous layers on top of the inner fibrous layers (40) and on top of the or each root insert (50), providing resin to the fibrous layers (40) and to the or each root insert (50) and curing the resin to form a prefabricated root section (26) for subsequent use in the manufacture of a wind turbine blade (10). Curing the resin to form the prefabricated root section (26) is conducted before removing the prefabricated root section (26) from the male mould (28).

摘要： A method of installing a wind turbine generator onto a floating foundation. The floating foundation has variable buoyancy and is pre-ballasted to float at a predetermined vertical position before installation of a wind turbine generator component onto the floating foundation. A wind turbine generator component supported by lifting equipment is brought towards the floating foundation until contact is made with the floating foundation. Ballast is removed from the floating foundation to increase the buoyancy of the floating foundation such that weight of the wind turbine generator component supported by the floating foundation is increased from substantially zero to substantially the entire weight of the wind turbine generator component. The vertical position of the floating foundation is substantially unchanged during transferring weight of the wind turbine generator component onto the floating foundation.

摘要： A method for performing maintenance on an outer surface of at least one wind turbine part, such as a tower (2), a nacelle (3) or a wind turbine blade (5), of an offshore wind turbine (1) is disclosed. An access system (10) is transported to a site of the offshore wind turbine (1), and the access system (10) is transferred to a transition platform (6) at a lower part of the offshore wind turbine (1), while operating the offshore wind turbine (1) in accordance with a normal operating mode. Normal operation of the offshore wind turbine (1) is then stopped, and maintenance is performed on an outer surface of at least one wind turbine part (2, 3, 5) of the offshore wind turbine (1), using the access system (10). When the maintenance has been completed, normal operation of the offshore wind turbine (1) is restarted in accordance with a normal operating mode. Normal operation of the offshore wind turbine (1) is only stopped while the actual maintenance takes place. Thereby the loss in power production is minimised.

摘要： A wind turbine blade includes a hub end, a tip end, a leading edge, a trailing edge, a pressure side, and a suction side. At least one boundary layer fence is located on at least one of the pressure side and the suction side of the blade. A plurality of passages is formed in the fence. Each passage has an inlet on a hub end side of the fence and an outlet on a tip end side of the fence and a cross-section that decreases from the inlet to the outlet. Each outlet is oriented to discharge air towards the trailing edge of the blade.
