Performance analysis of SAPF based on self tuned harmonic filter with fuzzy logic controller

Abstract

This article present software implementation, evaluation and simulation of three phase three wire(3-ph-3w) shunt active power filter (SAPF). It is able to harmonic mitigation, reactive power mitigation and power factor correction (PFC) under balanced diode rectifier nonlinear load with resistive inductive load as well as time series change of supply voltage amplitude. The p-q theory with self-tuning harmonic filter (STHF) is exercised for fundamental reference supply current generation. The novelty of control topology implemented in proposed brief is brought STHF which directly extracts voltage and current fundamental components in α-β axis without use of synchronizing unit vector element. Fuzzy logic based controller has been designed in MATLAB/Simulink platform to evaluate system performance under non-linearity and time series supply voltage amplitude variation. It will be proved that a define approach has good dynamic response. A simulation performance and results will illustrate better performance in comparison with classical extraction methods will be obtained. The usefulness of proposed SAPF is demonstrated through simulation using sim-power-system and embedded function integrated in MATLAB/Simulink.
