Implementation of Unified Power Quality Conditioner Based on Variable Phase Angle Control Method

This paper investigates the power quality problems which occur frequently in supply and suggests a method to mitigate by implementation of UPQC. P-Q generally concern with voltage sags/swells harmonic currents. Custom Power (CP) devices that these have gained more attention recent decades. UPQC is Designed, modelled setup experimentally sag/swells currents three phase systems. consists Dynamic Voltage Restorer (DVR) Active Filter (APF). proposed controller algorithms effectively compensates sag/swell keeping load amplitude at 0.9-1 per unit eliminates current harmonics 5% less than Total Harmonic Distortion,simultaneously.
