Performance evaluation of a three phase shunt active power filter for power quality improvement

Abstract

This paper deals with the performance evaluation of a three-phase, Shunt Active Power Filter for Power Quality Improvement. Power Quality problems can be addressed using Shunt Active Power Filters. A simulation model based on mathematical model of a three-phase, Shunt Active Power Filter has been developed. The results show an inherent power quality improvement in terms of reduced Total Harmonic Distortion (THD) of source current. It also exhibits Power Factor Correction (PFC) properties to a large extent as the source current and source voltage are in phase.
