1001- ICIEA

In the present-day power system with renewable sources, Doubly Fed Induction Generator (DFIG) is broadly preferred in wind power technology. DFIG has the dynamic capability of coordinating the pitch angle of turbine blades and limiting DFIG power output. This paper presents a PID-type fuzzy logic controller (PID-type FLC) approach for the robust regulation of DFIG power based wind turbine at variable wind speed. The PID-type FLC is proposed and incorporated in the pitch angle control (PAC) to enhance rotor speed and active power regulation of DFIG. Matlab/Simulink software based realtime simulations are performed for observing the relative performances of the proposed PID-type FLC for PAC as compared to the conventional proportional pitch control combined with proportional-integral pitch compensation. The simulation results substantiate the improvements in DFIG performance with the proposed control scheme at different operating conditions.
