ABSTRACT:
The invention relates to a management system for the operation of a wind turbine, which regulates the power output of the turbine. The wind turbine includes a rotor with at least one rotor blade that is positioned at an adjustable angle to the rotor. The management system regulates the rotor speed within a predefined wind speed range by varying the rotor blade angle in order to set a nominal output and reduces the output in excess of a defined wind-speed-dependent threshold value. The threshold value is a defined rotor blade limiting angle.
