  • Method and system for operating a wind energy installation
    Patent number: 8247913
    Abstract: A method for operating a wind energy installation and a system for implementing the method. An oblique incident flow value, which represents the difference between the wind direction and the direction of a rotor axis of the wind energy installation, and a load value, which represents the load state of the wind energy installation, are determined. A total load value is determined based on the load value and the oblique incident flow value. The rotor rotation speed is reduced when the total load value is above a first limit value. The wind energy installation is shut down when, in addition, a second limit value is exceeded. The method makes it possible to react objectively to oblique incident flows and can reduce a load on a wind energy installation without causing large yield losses.

  • Means for adjusting the rotor blade of a wind power plant rotor
    Patent number: 6783326
    Abstract: Two independent adjusting systems are recommended for each rotor blade (6) for blade angle adjustments of the rotor blades (6) of the rotor of a wind power plant, assuring full redundancy of the blade angle adjustment. By suitable control of the individual adjustment paths of the two adjustments systems, additional advantageous effects can be gained, such as good lubricant distribution and/or even load distribution over time (FIG. 1).
