A METHOD OF OPERATING A WIND TURBINE WITH PITCH CONTROL, A WIND TURBINE AND A CLUSTER OF WIND TURBINES

摘要

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 comprises the sequential steps of: reducing the generated power, allowing an intermediate increase in the generator speed, and - reducing the generator speed by a means of pitching the wind turbine rotor blades.
