In recent days, most of the equipment is based on power electronics and often leads to power quality problems. Conventional equipments for power quality enhancement are not sufficient to meet the increasing applications and so it is very important to develop a dynamic solution to power quality problems. Hence, to meet both supply voltage imperfections and load current abnormalities a custom power device unified power quality conditioner (UPQC) is employed. It is a combination of series and shunt converters connected together with a common direct current (DC) link capacitor. This paper deals with the simulation of UPQC system through synchronous reference theory for series converter control and instantaneous active and reactive power theory or PQ theory for shunt converter control. The simulation is carried out using MATLAB/SIMULINK tool and results are presented under distorted source conditions, voltage sag and swells conditions.
