Performance Improvement of IUPQC in Distribution System under Abnormal Conditions Using FLC

Abstract

This paper proposes a new connection for a Interline Unified Power Quality Conditioner (IUPQC) to improve the power quality of two feeders in a distribution system. An IUPQC consists of a series voltage-source converter (VSC) and a shunt VSC both joined together by a common dc bus which is placed in between two different independent feeders to regulate the bus voltage of one of the feeders while regulating the voltage across a sensitive load in the other feeder. In the earlier case IUPQC is operated with VSC’s with Proportional plus Integral (PI) controller to mitigate harmonics& sags. The structure, control and capability of the IUPQC with Fuzzy Logic Controller (FLC) at Faults & Swells are discussed in this paper. The efficiency of the proposed configuration has been verified & compared with PI configuration through simulation studies using MATLAB/SIMULINK.
