Abstract
The invention relates to a wind energy plant with a nacelle, a generator located in the nacelle, a tower and a yaw bearing to adjust the nacelle orientation into the wind, such that the yaw bearing is located under the nacelle in a vertical yaw displacement and the nacelle is supported on the yaw bearing above a vertical shaft section of the same length as the yaw displacement.
Claims4
A method comprising:
- determining an anticipated pitching moment of a wind energy plant to be formed, wherein the wind energy plant to be formed comprises a nacelle, a generator located in the nacelle, a tower, a single yaw bearing on top of the tower, and a vertical shaft section supporting the nacelle;
- determining an anticipated, height-dependent thrust moment of the wind energy plant to be formed for nominal operation of the wind energy plant;
- determining a height position in which a total of the anticipated pitching moment and the anticipated, height-dependent thrust moment is at a minimum;
- identifying the height position as a position of the single yaw bearing of the wind energy plant to be formed;
- and
- forming the tower of the wind energy plant and installing the single yaw bearing at the height position, wherein a vertical shaft section extends above the yaw bearing.
