This paper presents a study on UPQC for power quality improvement. The development in various power electronics based devices has a significant impact on the quality of the power supply. So problems arise like harmonics, voltage sag, swell due to this reason should be solved for good power quality. The UPQC (Unified Power Quality Conditioner) is able to compensate voltage and currently based distortion simultaneously at a time and also independently. UPQC is a combination of series and shunt APF. The control strategy is based on UVT generation method for series APF and PQ theory is used for controlling Shunt APF. Simulation has been carried out in MATLAB and the results are quite satisfactory as per IEEE 519-1992 harmonic standard.
