Abstract

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.
