Modeling and Simulation of Dynamic Voltage Restorer (DVR) for Enhancing Voltage Sag

Abstract

The aim of this paper is to summaries the fundamental aspects of voltage sag production and their effects on power quality as well as enhancing this power quality in distribution network, using FACTS (Flexible AC Transmission System) Devices i.e. Dynamic Voltage Restorer (DVR). DVR is a powerful custom power device for short duration voltage compensation, which is connected in series with the load & hence it possesses some advantages. (In this paper detailed modeling and simulation and analysis of the DVR device is presented).
