Abstract: An offshore wind turbine generator comprises a tower 1 and a platform 2. The tower 1 is provided with a side door 4 accessed from the platform 2 using a stairway 5 leading to an upper platform 6. The upper platform 6 is formed from the upper surface of a cabinet 7 which houses a diesel backup generator. Both the backup generator and the cabinet 7 are mounted to the tower 1 by bolts, such that the cabinet and backup generator are fully supported by the tower 1. A diesel fuel tank 12 is also mounted to the tower 1 by bolts. The fuel tank supplies diesel fuel to the backup generator.

Abstract: A node structure (12, 14) for connecting two or more convergent members (16, 26) of a lattice frame to each other and to one or more other members of the lattice frame. The node structure (12, 14) comprises a pair of opposed spaced-apart faces (30) that are substantially planar and substantially parallel to each other. At least one pair of root formations (32) with respective central longitudinal axes define an interior angle between them, those axes diverging outwardly for alignment with respective members of the lattice frame and converging inwardly between the faces (30). An inner connecting wall (34) between the root formations (32) of the pair connects concave-curved inner edges (36) of the faces and extends in a concave curve around the interior angle to join the root formations (32) of that pair.

Abstract: The present invention relates to operation of a wind turbine using a power storage unit, such as a rechargeable battery, to power a group of power consuming units during grid loss. The wind turbine comprises a number of power consuming units being grouped into at least a first group and a second group, a first electrical converter for connecting the generator to the electrical grid, and a second electrical converter for connecting the electrical generator to the power storage unit. Upon detecting an occurrence of the grid loss, the generator is operated to ensure sufficient power of the power storage unit to operate the first group of power consuming units.

Abstract: The present invention relates to an assembly of two structural parts of a wind turbine wherein the structural parts are to be connected in a flange-to-flange connection by a number of bolts and such that a flange of the first structural part and a flange of the second are centrally and rotationally aligned whereby a first borehole in the flange of the first structural part is matched and aligned with a corresponding first borehole in the flange of the second structural part. The structural parts may for example be a tower section or a foundation section. The assembly further comprises a first and a second rotational guide member releasably attached to each of the flanges of the structural parts. Each of the rotational guide members comprises a U-shaped or L-shaped structure of a first leg portion and a second leg portion connected by a central portion, the first leg portion ending in a positioning portion shaped to be inserted into a borehole of the flange, and the second leg portion comprising a stop member, and for at least one of the rotational guide members the structure comprised in the rotational guide member is U-shaped. The stop member of the first rotational guide member is configured for abutment to the second leg portion of the second rotational guide member when the flanges of the first and second structural parts are centrally and rotationally aligned. The invention further relates to a method of positioning and connecting two structural parts of a wind turbine as described above. The method includes first centrally aligning the structural parts with the flanges face-to-face and then rotating the structural part relative to each other until the rotational guide members come into contact with each other.

Abstract: A power pack is located within a housing on the platform of a wind turbine generator tower. The power pack is supplied from a fuel tank. With the door of the housing open, the power pack may be removed for servicing and repair by using a U-shaped support structure to which an electric motor is mounted. Two support rails permanently located within the housing support the housed power pack. A chain attached to the power pack is driven by the motor to remove the power pack from the housing by sliding the power pack along the support structure. A pulley arrangement reduces the necessary torque. After removing the power pack from the housing, a crane is used to lift the power pack from the platform and to lower it down to a sea vessel. The crane may also be used in the refilling of the fuel tank by hauling a fuel line from a sea vessel up to the platform and connecting it to the fuel tank.

Abstract: A node structure for connecting a member of a lattice frame to one or more other members of the frame comprises a hollow brace having opposed walls that converge outwardly at an acute angle in cross-section toward a central plane to connect at an outer edge. At least one root portion has a central longitudinal axis extending outwardly in the central plane of the brace for alignment with a member of the frame. The root portion has an inner end cut away at opposite sides around the central plane to leave a joining surface that intersects the converging walls of the brace while embracing an outer region of the brace extending inwardly from the outer edge.

Abstract: A method of controlling a floating-body wind turbine power generating apparatus including a wind turbine generator disposed on a floating body includes a pitch-angle increasing step of increasing a pitch angle of a blade of the wind turbine generator when the wind turbine generator is stopped, so that an aerodynamic braking force is applied to a rotor of the wind turbine generator. In the pitch-angle increasing step, a first change rate of the pitch angle of the blade in a first period during which the wind turbine generator is in an inclining motion toward an upwind side from a vertical direction due to sway of the floating body, is smaller than a second change rate of the pitch angle of the blade in a second period during which the wind turbine generator is in an inclining motion toward a downwind side from the vertical direction due to the sway of the floating body.
