This project deals with modeling and simulation technique of a Dynamic Voltage Restore (DVR).The DVR is a dynamic solution for protection of critical loads from voltage sags / swells. The DVR restores constant load voltage and voltage wave form by injecting an appropriate voltage. Present novel structure improves power quality by compensating voltage sag and voltage swells. The transient response of any natural system is the way in which the response of the system behaves as a function of time. Electromagnetic transient studies have always played an essential behavior of the system in the event of different forms of transient phenomena, which can hardly be achieved by other means. This project addresses the transient studies of electrical networks with embedded, power electronics-based, FACTS and Custom Power (CP) controllers.

It provides complete, clear, and detailed explanations of advanced electri- cal engineering concepts illustrated with numerous practical examples.
