Abstract :
This paper presents an application of Fuzzy Logic Controller(FLC) to regulate the reactive-power of the Self Excited InductionGenerator (SEIG) driven by Wind Energy Conversion Schemes(WECS). The proposed FLC is used to tune the integral gain (KI) ofProportional plus Integral (PI) controller. Two types of controls, for thegenerator and the wind turbine, using FLC algorithm have beenintroduced in this paper. The reactive-power control is performed toadapt the terminal voltage via self excitation. The active-power controlis conducted to adjust the stator frequency through tuning the pitchangle of WECS blades. Both controllers utilize the Fuzzy technique toenhance the overall dynamic performance. The simulation result depictsa better dynamic response for the system under study during the startingperiod, and load variation. The percentage overshoot, rising time andoscillation are improved by the fuzzy controller compared to that withPI controller type.
