Interline Unified Power Quality Conditioner: Design And Simulation

Abstract
Abstract—This paper proposes a new connection for a UPQC to improve the power quality of two feeders in a distribution system. A UPQC consists of a series dynamic-voltage restorer (DVR) and a shunt active power filter (APF) both joined together by a common dc bus. It is demonstrated how this device can be connected between two independent feeders to regulate the bus voltage of one of the feeders while regulating the current across a load in the other feeder. Since the UPQC is connected between two different feeders (lines), this connection of the UPQC will be called an interline UPQC (IUPQC). The structure, control and capability of the IUPQC are discussed in this paper. The efficacy of the proposed configuration has been verified through simulation studies using Matlab.
