Abstract: This project proposes effective work to increase the power quality in the power system by using a Unified Power Quality Conditioner (UPQC) The advanced use of power electronic devices introduces harmonics in the power system which creates a problem in the quality of power delivered. Although several methods are there for improving power quality standards, including the use of active and passive filters, and Hybrid filters have been developed, these methods face issues and are ineffective due to the growing number of applications. The UPQC is an advanced technique for mitigating voltage and load current supply fluctuations. In this project the combination of series active filter and shunt active filter is studied. UPQC is used to reduce the power quality issues like harmonics and sag. The shunt active filter and series active filter performs the simultaneous elimination of current and voltage problems. The project work presents the working of the UPQC filter in such a way that the harmonics are reduced.
