The present invention further relates to a method of installing a tower of a wind turbine using the installation system.

Provided is a method for producing a wind turbine, the method including the steps of: a) providing a nacelle structure, b) providing a module to be mounted to the nacelle structure in a hanging position, and c) moving the module relative to the nacelle structure and at least partially through the nacelle structure at an erection site until the module is in the hanging position on the nacelle structure. This has the advantage that the transport of the nacelle structure and the module may be conducted not in hanging position. Thus, a height of the nacelle structure during transport can be lowered.

A method of erecting a wind turbine on a wind turbine site, the wind turbine comprising a turbine tower and a nacelle. The method comprises the following steps: providing a plurality of tower sections being arrangeable upon each other in a vertical orientation in a tower structure to form the turbine tower; providing at least one damper unit configured to dampen oscillations of the turbine tower; attaching a damper unit to one of the plurality of the tower sections on an outside thereof, and subsequently arranging the tower section in the tower structure, and arranging the nacelle on top of the tower structure while the damper unit is attached to a tower section in the tower structure.

An enclosure with a frequency mixing and absorbing device on an outer surface is provided. The frequency mixing and absorbing device includes a deformable body located on an outer surface of the enclosure, the deformable body includes a flexible body and/or an elastic body, the flexible body is a flexible hollow body or a flexible solid body, the elastic body is an elastic hollow body or an elastic solid body. When the direction of the incoming flow is from left to right, it acts on the deformable body at a windward side, that is, the change of pressure will be converted into the volume change of the deformable body. In this way, the fluctuating energy of the incoming flow can be absorbed and stored by the deformation of the deformable body, and the fluctuating energy is transferred to the volume change.
