Abstract
This paper shows a far reaching performance analysis of Fuzzy logic controlled Voltage Source Inverter (VSI) based unified Power quality conditioner (UPQC) utilized or applied at various distribution levels for improvement of the electric power quality. As of late Unified Power Quality conditioner (UPQC) is being utilized as a widespread dynamic power molding gadget to relieve both voltage as well as current harmonics in a polluted power system network. Fabrication of UPQC is done implying both current source and voltage source inverter. In the present paper reference and switching signals are derived using Fuzzy logic controller and robust hysteresis band PWM techniques. In this paper, Fuzzy Logic based control scheme has been developed for the production of compensating voltages. Voltage and current harmonics are eliminated with great precision from the system by resultant compensation framework. Broad simulation results utilizing Matlab/Simulink and Simpowersystem programming for R-L load associated through an uncontrolled bridge rectifier is introduced for execution assessment.
