Abstrakt

With the increase of wind turbine dimension and capacity, the wind turbine structures are subjected to prominent loads and fatigue which would reduce the lifetime of wind turbines. Individual pitch control (IPC) is used in this paper to attenuate the blade root bending moment and the tilt and yaw moments and fatigue. The loading transfer from rotational coordinate system to the fixed coordinate system of the wind turbine is analyzed. In order to make the simulation results more reliable, the wind turbine code FAST is applied to doubly fed induction generator (DFIG) based power system to demonstrate the correctness of individual pitch control strategy. The performance of the proposed control method is tested and compared with that using collective pitch control (CPC), demonstrating the effectiveness of individual pitch control of wind turbines.
