Development of controllers for the dynamic voltage restorer

Abstract

The proliferation of voltage sensitive equipment has made industrial processes more vulnerable to supply voltage deviations. Such voltage deviations in the form of voltage sag will cause severe process disruptions resulting in substantial production loss. Therefore cost effective solutions to ride through momentary power supply disturbances have attracted much research attention. Among several novel custom power devices, the Dynamic Voltage Restorer (DVR) for compensating voltage disturbances in distribution systems is a recent invention.
