摘要：The main objective of this project is to ensure the power quality. Power quality has become an importantissue for several reasons e.g. modern society‟s growing dependence on electricity and the fact that the poor powerquality may generate significant economic losses in few moments. Probable power quality problems are harmonic,flicker, voltage dips and supply interruptions. The power quality may be improved by using filters and compensators.This thesis introduces a new concept of optimal utilization of a unified power quality conditioner (UPQC).Through thisproject we are Experimentally Simulating and explaining the optimal utilization of a unified power quality conditioner(UPQC). The UPQC Converter is controlled to perform simultaneous operation of voltage sag compensation and loadreactive power sharing when additional loads are added. The active power control approach is used to compensatevoltage sag and is integrated with theory of power angle control (PAC) of UPQC to coordinate the load reactive powerbetween the two inverters.Unified power quality conditioners (UPQCs) allow the mitigation of voltage and current disturbances that couldaffect sensitive electrical loads while compensating the load reactive power. This paper deals with unified powerquality conditioner (UPQC), which aims at the Voltage Sag compensation by using Solar Power to compensate duringAdditional Loads requirements. The main purpose of a UPQC is to compensate for voltage imbalance, reactive power,negative-sequence current and harmonics. In this paper, unified power quality conditioner (UPQC) is designed andsimulated by Artificial Neural Network theory. The proposed system is comprised of series and shunt inverters whichcan compensate the sag, swell and unbalance voltage, harmonics and also the reactive power. PI controller is used tostabilize DC link voltage and balance the active power between the shunt and series inverters. The capacity of seriesand shunt inverters is calculated through loading calculations of these inverters applying phasor diagram to increase thedesign accuracy.
