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.
Claims14
A wind energy plant comprising:
- a nacelle;
- a generator located in the nacelle;
- a tower;
- and
- a yaw bearing configured to rotate relative to the tower and to adjust an orientation of the nacelle, wherein the yaw bearing is positioned spaced from the nacelle by a vertical yaw displacement, and the nacelle is supported by the yaw bearing above a vertical shaft section of the same length as the yaw displacement.
2 more elements
A shaft section of a wind energy plant comprising:
- a first end coupled to the nacelle and a second end coupled to a tower by a yaw bearing such that the shaft section is configured to rotate relative to the tower, the shaft section being cylindrical.
A method comprising:
- determining an anticipated pitching moment of a wind energy plant,
- determining an anticipated, height-dependent thrust moment of the wind energy plant for nominal operation of the wind energy plant,
- determining a height position in which a total of the pitching moment and the thrust moment is at a minimum, and
- identifying the height position as a position of a yaw bearing of the wind energy plant.
