Paper Title
Comparative Analysis of Filters to Mitigate Harmonics For Power Quality Enhancement
Abstract
Due to the advancement in power electronic equipments and increase in the usage of non-linear loads in power
distribution system, the undesirable harmonics are introduced that degrade the quality of power. Presence of harmonics are
always detrimental to power system that results in irreversible failure of electrical components, sometimes apart from
frequently known heating issues in it. There are several approaches that can be considered to compensate for harmonics in
power system with varying degree of effectiveness and approaches. The objective of this paper is to use passive filter and
Fuzzy logic controller based shunt active filter for harmonic mitigation and study their performance. The performance of
proposed filters is evaluated through computer simulation using Matlab R2010b/Simulink platform. Evaluating the
simulation results, the Fuzzy logic controller based shunt active power filter is more effective in reducing total harmonic
distortion and improving the power factor of the source signal when compared to passive filter.
