IMPROVEMENT OF POWER QUALITY USING SOLAR PV INTEGRATED UNIFIED POWER QUALITY CONDITIONER
Main Article Content
Abstract
This paper presents, the use of unified power quality conditioner (UPQC) to eliminate power quality issues. The solar PV panel with boost converter is integrated at the DC-link of UPQC. For extracting maximum power from PV panel the boost converter operates. The UPQC consists of the combination of shunt and series inverter. The voltage related power quality problems, such as voltage flicker, swell and sag are eliminated by series inverter. For eliminating the current related problems, such as current harmonics the shunt inverter is used in UPQC. Hence the UPQC performs the multi task, i.e. the voltage related problem as well as current related problems. The performance of solar PV integrated UPQC is simulated using power simulation software.
