A short dip in supply voltage, unnoticed by the majority of electricity consumers, can still stop an entire production line in highly sensitive industries such as computer chip manufacturing, oil refining ..etc.We have to develop and successfully introduce systems to overcome these obstacles by means of advanced power electronics. In this paper , a noval approach on active series & shunt power line conditioner upqc (unified power quality conditioner ) has been described. It is a combination of a STATCOM as well as DVR .a series compensating stage connected before the load in series with the mains using a matching transformer. UPQC can mitigate voltage sag, swell, voltage transient & voltage unbalance. UPQC can supply VAR to the load. DSP based controller is connected to UPQC in order to increase the system performance
