Abstract
A method of operating a pitch controlled wind turbine connected to the utility grid in response to an increase in wind velocity to above a predefined value. The method includes the sequential steps of: reducing the generated power, allowing an intermediate increase in the generator speed, and reducing the generator speed by pitching the wind turbine rotor blades. A wind turbine and a cluster of wind turbines is also contemplated.
