Abstract
Provided is a tower section arrangement for a guyed tower of a wind turbine, the tower section arrangement including: a tower section including a wall having an outer surface with a circumference, at least two brackets attached to the outer surface of the wall at different locations on its circumference, and at least two stay cables, wherein each stay cable is connected at its first end to one of the brackets and is configured for connection at its second end to a cable foundation, and wherein an angle (α) between each stay cable and a tangent to the outer circumference at the respective bracket has, in a top view of the erected wind turbine, a value of 90° when the respective stay cable is guyed.
Claims15
A tower section arrangement for a guyed tower of a wind turbine, the tower section arrangement comprising:
- a tower section including a wall comprising an outer surface with a circumference;
- at least two brackets attached to the outer surface of the wall at different locations on the circumference, wherein each of the at least two brackets comprises a single plate structure extending vertically between a first cross member and a second cross-member, the first cross member and the second cross-member being physically connected to the single plate structure and extending laterally from the single plate structure to adapt to a curvature of the tower section;
- at least two stay cables;
- wherein each stay cable is connected at a first end to one of the at least two brackets and is configured for connection at a second end to a cable foundation;
- wherein an angle (a) between each stay cable and a tangent to the circumference at the respective bracket has, in a top view of the erected wind turbine, a value of 90° when the respective stay cable is guyed.
A method for assembling a wind turbine, comprising the steps of:
- a) providing a tower section, the tower section including at least two brackets attached to an outer surface of a tower section wall and at different locations on a circumference, the at least two brackets each comprising a single plate structure extending vertically between a first cross member and a second cross-member, the first cross member and the second cross-member being physically connected to the single plate structure and extending laterally from the single plate structure to adapt to a curvature of the tower section;
- b) connecting at least two stay cables to the at least two brackets, wherein an angle between each stay cable and a tangent to the circumference at the respective bracket has, in a top view of an erected wind turbine, a value of 90° when the respective stay cable is guyed;
- and
- c) lifting the tower section with the attached stay cables onto a further already erected tower section.
