Performance enhancement of shunt active power filter with fuzzy and hysteresis controllers
0 likes585 views
The document presents a study on a three-phase shunt active power filter (SAPF) utilizing fuzzy and hysteresis controllers to enhance power quality by eliminating current harmonics in systems with nonlinear loads. The proposed SAPF model was simulated using MATLAB/Simulink, demonstrating superior performance compared to conventional controllers, with a total harmonic distortion (THD) of 5%, meeting IEEE standards. The results suggest significant improvements in the sinusoidal nature of the source current and overall power quality.

The Shunt Active Power Filter is used to eliminate current harmonics. The dc link control strategy is based on the fuzzy logic controller. Gating pulses for the Shunt Active Filter is generated using Hysteresis current controller based Pulse width modulation technique. The proposed model is simulated in MATLAB/SIMULINK. Simulation results show that the dynamic behavior is better than the conventional Proportional- Integral (PI) controller and is found to be more robust for changes in load. KEYWORDS: 1.
