This analysis demonstrates a new control strategy for an UPQC system that compensates current harmonics and voltage distortions.
This paper presents a novel control strategy for a Unified Power Quality Conditioner (UPQC) system to compensate power quality problems at the point of common coupling (PCC) in a distribution system. The proposed control strategy for shunt active filter uses a simple mathematical concept which reduces the complexity in design. Simulation study shows that an UPQC with proposed control algorithm effectively compensates current harmonics, unbalance and reactive power. The performance of UPQC is verified for a system with voltage distortions, sag /swell using MATLAB/SIMULINK. Based on the simulation results obtained, harmonic and power quality analysis has been done.
