Fuzzy algorithm for supervisory control of self-excited induction generator

Abstract EN

This paper presents an application of Fuzzy Logic Controller (FLC) to regulate the reactive-power of the Self Excited Induction Generator (SEIG) driven by Wind Energy Conversion Schemes (WECS).

The proposed FLC is used to tune the integral gain (KI) of Proportional plus Integral (PI) controller.

Two types of controls, for the generator and the wind turbine, using FLC algorithm have been introduced in this paper.

The reactive-power control is performed to adapt the terminal voltage via self excitation.

The active-power control is conducted to adjust the stator frequency through tuning the pitch angle of WECS blades.

Both controllers utilize the Fuzzy technique to enhance the overall dynamic performance.

The simulation result depicts a better dynamic response for the system under study during the starting period, and load variation.

The percentage overshoot, rising time and oscillation are improved by the fuzzy controller compared to that with PI controller type.
