The powerful wind generators, producing electric power on the order of megawatts are with impressive sizes.The studies on the interaction between the IP-6 air flow and the wind turbine usually assume the airflow as homogeneous in vertical direction.While for smaller wind turbines this assumption does not lead to significant inaccuracies, for powerful generators the vertical gradient of the wind velocity causes a dependence of the aerodynamic interaction from the angle of rotation of the Arduino Boards propeller and leads to a significant cyclic variability of the forces and moments acting on the blades, even for a flow considered as stationary in time.
The study of this problem is important for strength loads and fatigue calculations as well as for an implementation of an individual pitch-control of the blades, which could allow a synthesis of a regulation depending on the angular position of the turbine.This could contribute to higher performance and higher reliability.
