A wind park having an auxiliary power supply

Abstract: A turbine farm comprises a plurality of individual turbines each having an auxiliary component circuit. The farm further comprises; a master transformer arranged to be coupled between each of the plurality of individual turbines and an electrical grid and an auxiliary transformer coupled between the sub-station transformer and the auxiliary component circuit in each of the individual turbines. When in use power is transmitted from the sub-station transformer back to each auxiliary component circuit.

Wind turbine blade control

Abstract: A wind turbine variable is controlled by detecting air flow conditions in front of the leading edge of the blade. One or more Laser Doppler Anemometers are mounted on or incorporated into the blade to determine air flow velocity in the region in front of the leading edge of the blade. The measured flow conditions may be used to control the position of a control surface such as a trailing edge flap or the rotor speed. The LDAs may comprise lasers of different frequencies to enable more than one component of flow velocity to be measured.

Wind turbine blade and method for manufacturing a wind turbine blade

Abstract: Wind turbine blade includes a first blade part and a second blade part, the blade parts being bonded by bonding means forming a bond. To reduce peel stresses of the bond and reduce the risk of crack formation, an edge portion of the bond is covered by a low elastic modulus adhesive joint bridging a gap between the first blade part and the second blade part.

A wind turbine, a high current connector and uses hereof

Abstract: The invention relates to a wind turbine (1) connected to a utility grid or another electric load. The wind turbine (1) comprises at least one electric generator (6) generating a high current, at least one substantially inflexible conductor (13) conducting the current, a high current connector (15) including a housing (18) capable of conducting the current, where the housing (18) comprises two or more openings (17) for accommodating at least two conductor ends (16) of the conductor (13). The wind turbine (1) is characterized in that, the openings (17) of the high current connector (15) comprise one or more connection means (20) for providing an electric connection between said conductor ends (16) and said housing (18), said connection means (20) configured for allowing substantially unrestricted movements of the conductor ends (16) in the conductors (13) longitudinal direction. The invention further relates to a high current connector (15) and uses hereof. V

Wind turbine generator having an eddy current brake, wind turbine having such a generator, and associated methods

Abstract: A wind turbine generator includes an outer housing, a drive shaft rotatably mounted within the outer housing, stator and rotor assemblies positioned within the outer housing and movable relative to each other, a heat exchanger, and a blower having a rotating plate for generating a fluid flow circuit within the generator for transporting heat from the stator and rotor assemblies to the heat exchanger. An eddy current brake having a rotating member is located within the outer housing and is positioned in the fluid flow circuit such that fluid moving in the flow circuit cools the first rotating member. The blower and the eddy current brake may be integrated, such as by having the rotating plate of the blower serve as the rotating member of the eddy current brake. A wind turbine having such a generator, as well as a method of operating a wind turbine generator is also disclosed.
