Pitch angle Control of Brushless Doubly-Fed Generator In Variable-Speed Wind Power Generation System

This paper presents the optimum speed ratio of BDFG used the pitch angle control for maximum the active power, when the wind turbine operated accord the rotor speed varies, The optimal rotor speed can make the power of wind at the maximum values. the proposed control strategy will vary the pitch of blades a few degrees every time when the wind changes. The control of active and reactive power achieved by the filed oriented technique and the complete variable speed wind turbine analyzed and examined in different wind speed conditions used MATLAB/Simulink.
