Abstract: An electrical power generator for a wind turbine comprising: a generator housing, a stator at a radially outward position and a rotor in a radially inward position, wherein the rotor comprises a cylindrical ring structure arranged about a rotational axis, R, and defining a central hollow portion. The electrical power generator further comprises a rotor shroud attached to the generator housing and which extends about the rotational axis, R, wherein the rotor shroud includes a dome portion that extends into the central hollow portion of the rotor so as to protect the cylindrical ring structure of the rotor. Advantageously, the rotor shroud provides a tunnel-like surface that extends into the central hollow portion of the generator so as to prevent objects such as tools from contacting components of the rotor. The invention also relates to a method for 15 assembling such an electrical power generator with a rotor shroud.

Abstract: A tagline control system for handling a wind turbine component during an operation on a wind turbine using a lifting apparatus. The tagline control system includes a tagline control module (74, 164) having a housing (80), at least two winches (126,128) disposed within the housing and each having a tagline cable (130, 132), a controller (146) disposed within the housing and operatively coupled to the at least two winches, and a power source (148) disposed within the housing (80) and operatively coupled to the at least two winches. A method of handling a wind turbine component during an operation on a wind turbine using the lifting apparatus includes coupling the tagline control module to the lifting apparatus and to a wind turbine component, and operating the tagline control system to effectuate the position of the wind turbine component.

Abstract: A transport frame (100, 102) for a nacelle (14) includes a pair of lower nacelle mounts (128, 130) and a pair of upper nacelle mounts (204, 206). Each of the lower nacelle mounts (128, 130) includes a plurality attachment points for attaching to the nacelle (14) at a plurality of different widths. Each of the upper nacelle mounts (204, 206) includes a plurality of attachment points for attaching to the nacelle (14) at a plurality of different widths. The pair of lower nacelle mounts (128, 130) and the pair of upper nacelle mounts (204, 206) are adjustably positioned to allow the transport frame (100, 102) to attach to the nacelle (14) at a plurality of different heights. The ability of the transport frame (100, 102) to attach to the nacelle (14) at a plurality of different widths and heights allows the transport frame (100, 102) to be used on nacelles (14) having different sizes. Methods of using the transport frames (100, 102) are also disclosed.

Abstract: A tool chain (10) is provided for performing a method of removing internal components such as a bearing cassette (64) from the interior of a generator (12) and/or a gearbox (14) of a wind turbine. The tool chain (10) includes a tube (30) that extends through the interior of the generator (12), at least one clamp element (36) that concentrically fixes the tool chain (10) in position on at least one output shaft (60, 62) of the gearbox (14), and a sliding tool (50) that moves along the tube (30) into and out of the generator to couple with and pull out internal components to be repaired or replaced. For example, the tool chain (10) can remove the bearing cassette (64) located adjacent the junction of the gearbox (14) and the generator (12) without necessitating disassembly of the gearbox (14) from the generator (12).

Abstract: A wind turbine (1) comprising a tower (2) and one or more nacelles (3) mounted on the tower (2) is disclosed, at least one of the nacelle(s) (3) housing one or more drive train components (9,10,11) and a transportation system for moving drive train components (9,10,11) of the wind turbine (1). The transportation system comprises one or more sliding rails (15) configured to carry a drive train component (9, 10,11) during movement, and one or more sledges (19). Each sledge (19) is movably connected to a sliding rail (15), and configured to be attached to a drive train component (9,10,11), thereby allowing the drive train component (9,10,11) to move along the sliding rail(s) (15). Each sliding rail (15) comprises two or more rail modules (6,13,14) being detachably connected to each other along a direction of movement defined by the sliding rail (15).

Abstract: A transportation system (300) for, and a method (1104, 1106, 1108) of loading for transportation of, a segment (330) of a wind turbine tower are disclosed. The system has a transportation platform (304), the transportation platform having a centreline (320), and a segment support (306, 310) mountable on the transportation platform. The segment support is configured to permit tilting of a supported segment with respect to a pivot point (308) of the support. The segment support is further configured to receive a segment such that the centre of gravity (342) of the segment is offset transversely from: the support pivot point; and from the transport platform centreline. The segment support is also configured to, having received the segment, permit tilting of the segment with respect to the support pivot point to a rest position, and in the rest position the centre of gravity of the segment is alignable vertically with the transport platform centreline.
