Adaptive Fuzzy, Fuzzy PI and PI Controller based Shunt Active Power Filter for Harmonic Reduction

The present paper describes Adaptive Fuzzy logic and FuzzyPI and PIcontroller Shunt Active Power Filter (SAPF) designed for harmonic compensation and reactive power under variable conditions. Therefore the power quality can be increase efficiently by using this Shunt hybrid active power filter. The main purpose of this work is Fuzzy logic and PI controller based regulator, the shunt active power filter to compensate harmonics and reactive power by nonlinear load to enhance power quality is implemented for three wire system The various simulation results are presented under steady state conditions and performance of AdaptiveFuzzy and FuzzyPI and PIcontrollers is compared. Simulation results obtained show that the performance of Adaptivefuzzy controller is found to be better than Fuzzy PI and PI controller
