Power Quality Improvement by Mitigation of Harmonics Using Shunt Active Power Filter and Its Comparative Analysis.
Year: 2026
Type: article
Abstract: The paper will discuss the application of Shunt Active Power Filter (SAPF) to enhance the current quality in a nonlinear load electrical system. Two options of controllers, i.e. a hysteresis current controller and a fuzzy logic controller are conducted in a comparative simulation study. The two schemes are created in MATLAB/Simulink and evaluated with the same operating conditions. The uncompensated system results in a very skewed source current, but the addition of SAPF seriously reduces harmonic content and enhances the quality of the waveform. The hysteresis-based controller reduces the source-current THD to 2.08% whereas the fuzzy logic controller reduces it to 1.8%. This demonstrates that both methods meet the IEEE-519 requirements, but the fuzzy logic method is more smooth to compensate, can be more flexible and work better overall
