Application of fuzzy logic control for reactive power and D.C. capacitor voltage control of Doubly Fed Induction Generator during external faults

Abstract

This paper presents application of fuzzy logic control for Reactive Power and D.C capacitor voltage control of Doubly Fed Induction Generator (DFIG) during external faults. In order to apply fuzzy logic controller, a model is developed in MATLAB/SIMULINK. Reactive power is control from rotor side converter and d.c. capacitor voltage is control from grid side converter. The simulation results are presented to illuminate the effectiveness of the fuzzy controller compared with conventional PI controller in the DFIG system.
