Abstract

The wind turbine (1) comprises a rotor (2) with a number of blades mounted for rotation about a mainly horizontal axis, and the pitch of the blades of the wind turbine is controlled dependence on measured parameters to optimize the operation of the wind turbine with respect to produced energy under varying weather and wind conditions. By measuring mechanical loads on the blades (7, 8), and controlling the pitch of the blades of the wind turbine in such a way, that the measured mechanical loads are maintained below certain limits during operation, the control can be performed closer to the mechanical load limits of the blades without risk of exceeding these limits.
