- Abstract
Commencing with incandescent light bulb, every load today creates harmonics. Unfortunately, these loads vary with respect to their amount of harmonic content and response to problems caused by harmonics. The issue of harmonics is of great concern to engineers, building designers and also in industrial applications because they do not just distort voltage waveforms, but they can also overheat the building wiring, cause nuisance tripping, overheat transformer units, and cause random end-user equipment failures. Thus, power quality has become more and more serious with each passing day. As a result active power filters (APF) gain attention due to their excellent harmonic compensation. But still the performance of the active filter seems to be in contradiction with different control techniques. The main objective of this paper is to analyze shunt active filters employing fuzzy and PI controllers. The active and reactive power method (p-q) is used for the analysis. Extensive simulations were carried out; simulations were performed with balance, unbalanced and non sinusoidal conditions. Simulation results validate the dynamic behaviour of fuzzy logic controller over pi controller.
