Abstract: Provided is a wind turbine, including a tower and a damper module, especially a slosh damper module arranged in the tower, which damper module includes a frame with at least two elongated first frame ends at one side of the frame and at least two elongated second frame ends at the opposite side of the frame, which first and second frame ends are fixed to first and second fixation elements arranged at an inner wall of the tower, wherein the first frame ends are immovably fixed to the fixation elements while the second frame ends are fixed sliding relative to the fixation elements, wherein the first and second fixation elements are first and second plates fixed to the and extending horizontal from the inner wall, on which the first and second frame ends comprising flat support areas rest.

Abstract: A wind turbine includes a tower, a nacelle supported rotatably at a top portion of the tower, a main cable for transporting electrical energy produced in the nacelle to a bottom portion of the tower, and at least one auxiliary cable guided from the nacelle to an intermediate portion between the top and bottom portion and/or to the bottom portion of the tower, wherein the main cable includes a first loop, and the at least one auxiliary cable includes a second loop, and the first and second loops are configured for compensating, independently from each other, a movement of the respective cable due to rotation of the nacelle relative to the tower. Thus, movement of the auxiliary cables caused by yawing of the nacelle will not affect movement of the main cable.

Abstract: A wind turbine tower includes a door access opening in a down tower area of the tower. A hinged door panel covers the door access opening, with a ventilation opening defined through the door panel. A multi-sided intake structure, such as a box-like structure, is connected to an exterior of the door panel over the first ventilation opening. The intake structure extends transversely from the door panel and includes a top side, a bottom side, and at least two vertical sides extending between the top side and the bottom side. The vertical sides are open to air flow therethrough. The top and bottom sides may also be open to air flow therethrough. Air from multiple directions is drawn into an interior of the wind turbine tower through the intake structure and ventilation opening. A filtering system with first and second stage filters may be incorporated with any of the intake structures.

Abstract: The present disclosure is directed to a system and method for cooling or cleaning a slip ring assembly of a generator of a wind turbine. The slip ring assembly is at least partially enclosed in a slip ring compartment. In addition, the slip ring assembly includes an electrically conductive slip ring mounted to the rotatable shaft and a fixed conductive ring assembly having slip-ring contacting members mounted thereon. The conduit assembly is configured to direct fluid into the slip ring compartment so as to cool or clean the slip ring compartment. Further, the conduit assembly extends from a first end to a second end. More specifically, the first end is configured at or before an inlet of the generator assembly, whereas the second end is configured at the slip ring compartment.
