  • 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.
