Wind Power Plant

Abstract

The invention relates to a wind turbine (100) with a tower (10). The present invention is based on the task of advancing a wind turbine (100) in such a way that high degrees of efficiency in the use of input wind energy are maintained along with reduced production costs for wind turbines (100) and simple design features in the construction of the tower (10). The task is solved by said tower (10) being a timber-made hollow body, that said tower (10) consists of modules in the form of segments (16), which are arranged on top of each other, and that said segments (16) consist of timber panels (17, 18, 19, 20).

Description

[0001]This application is a continuation of U.S. application Ser. No. 12 / 449,414 and claims the benefit of priority accorded application Ser.

At the end of the nacelle, a rotor with a horizontally extending pivotal axis is arranged and connected to a generator. It is common practise to use three blade rotors, as they guarantee for a relatively consistent run. Wind turbines of this kind are highly advanced in terms of their efficiency in utilizing input wind energy. Nonetheless, existing wind turbines show significant economic disadvantages.

AI Technical Summary

Benefits of technology

"The present invention is a wind turbine with a timber-made hollow body, which is designed to maintain high efficiency in the use of input wind energy while reducing production costs. The tower is made up of glued timber panels that can be easily on-site mounted, and the closed construction of the towers protects the necessary fasteners from weather conditions. The tower diameter expands as it approaches the ground to increase its resiliency. The tower can be connected using glueing, bolting, or beads on both ends for on-site mounting. The tower can be made from different types of timber and can be closed at the top and / or bottom. The invention provides a wind turbine with improved efficiency and reduced transport costs."

Problems solved by technology

Nonetheless, existing wind turbines show significant economic disadvantages.

For example, the heavy weight of the rotor and its distance from the tower center which carries the pivot-mounted nacelle results in considerable torque at the tower top.

This leads to increased load on the tower along with a consequential increase in construction and manufacturing costs, resulting in high material costs for the tower.

Nonetheless, there are no timber grid towers existing for wind turbines, in as much as the attempt to construct timber skeleton framings for wind turbines uncovered two grave problems.

At this point, the tower construction requires smaller distances between the trusses of the skeleton framing, whereby the diameter that can be chosen for the tower is limited.

In terms of dimensioning, this results in very large and unwieldy and rod cross section radiuses, which are practically not manageable.

A significant problem in the construction of timber wind turbine towers is certainly posed by the restricted choices in planning regarding the available geometric options in the rotor area.

The external diameter of the tower cannot be easily enlarged.

Given that considerable loads result from the weight of the said rotor, the working loads cannot be easily absorbed by the components of the grid tower.
