Harmonics Mitigation Based on Fuzzy Logic Controller

The purpose of this study is to explain adverse effects of harmonics on the supply system and the methodologies to eliminate these in some extent. This work also explains the harmonics distortion as major concern related to the power quality and reliability. This work includes the designing of an automatic controller based fuzzy logic type, in which an intentional generation of harmonic wave in phase opposition of the system harmonics is done to nullify it. The obtained result is then compared with the results of conventional controller of power circuit containing number of nonlinear circuit elements.
