Wind Turbine, a Method for Assembling and Handling the Wind Turbine and Uses Hereof

Abstract

The invention relates to a wind turbine including a foundation and a tower positioned on the foundation where the tower includes more than one modules, where the modules each include a separate strengthening structure defining the outer edges of the module and wind turbine equipment, and where the more than one module are positioned substantially vertically on top of each other in an upright position within the tower. The modules are connected directly and / or indirectly through the strengthening structure, to the foundation (18). The invention further relates to a method for assembling a wind turbine at a wind turbine site and a method for handling more than one wind turbine modules.

Description

BACKGROUND OF THE INVENTION [0001] The invention relates to a wind turbine as specified in the preamble of claim 1, a method for assembling the wind turbine and a method for handling the wind turbine and uses hereof. DESCRIPTION OF THE RELATED ART [0002] A wind turbine known in the art typically comprises a wind turbine tower and a wind turbine nacelle positioned on top of the tower. A wind turbine rotor, comprising three wind turbine blades, is connected to the nacelle through a low speed shaft, which extends out of the nacelle front as illustrated on FIG. 1. [0003] The nacelle is typically provided with some, but typically not all, of the electrical equipment needed to transform, convert and in other ways handle the power being produced by the generator in the nacelle. With off-shore and land based wind turbines the rest of this power handling equipment is often placed on platforms inside the wind turbine tower. These platforms are typically mounted on fittings welded to the insid...

Benefits of technology

[0011] A further object of the invention is to establish an advantageous logistical system for providing a wind turbine tower with wind turbine equipment and to avoid reducing the towers fatigue limit when doing so. The Invention

Problems solved by technology

Another problem in mounting power handling equipment on platforms at the bottom of the tower is that it is inflexible, in that the platforms only fit towers of a specific diameter, and in that mounting and fitting of the platforms and the power handling equipment can first take place when the tower is manufactured and painted.

The unit is difficult to handle and transport in that it is large and heavy, and all the equipment in the unit has to be secured thoroughly, in that it has to be transported lying down and then erected at the mounting site.

Other equipment in the modules could be delicate electrical equipment, which could easily be damaged if the modules were e.g. transported lying down on one side.
