    摘要: The invention relates to a method of operating a wind farm intended for connection to an electric power network, which wind farm includes at least three wind turbine generator systems. At least one actual value for a wind speed or a parameter associated with wind speed is determined for each wind turbine generator system which are divided at least temporarily into predetermined groups. A first disconnect value is assigned to one group of wind turbine generator systems and a second different disconnect value is assigned to a second group of wind turbine generator systems. Actual values are assigned to disconnect values, and compared thereto. When the actual value exceeds the disconnect value the associated group of wind turbine generator systems is automatically disconnected.

    摘要: 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.
