The present invention addresses the problem of reducing the load exerted by a nacelle and wind forces upon a yaw bearing of a wind energy plant. The present invention provides 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 positioned beneath 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, characterized in that the height of the yaw bearing is selected such that at the yaw bearing, a total of a static pitching moment, attributable to a center of gravity in the nacelle in front of the yaw bearing, and an average thrust moment attributable to a wind load acting on an aerodynamic rotor is minimized, specifically that the total for an average thrust moment is approximately zero. |
