Wind Turbine: Angle of Attack

To minimize losses in performance the angle of attack of
the blade, depicted as in Fig. 2, is controlled by
rotating the blade about its axis. The amount the
blade is rotated about its axis is referred to as the
pitch angle.

In a method for blade load reduction control of a rotor of a
Wind turbine, the rotor includes a plurality of blades, and a
pitch angle of each blade is controllable by an actuator.
