Simulation and Implementation of Dynamic Voltage Restorer System

Dynamic Voltage Restorer (DVR) is a new concept of Flexible AC Transmission System (FACTS) controller with the unique capability for series compensation and power flow management among multi-line of a substation. The DVR employs a number of Voltage Sourced Converters (VSCs) linked at the same DC terminal, each of which can provide series compensation for the selected line of the transmission system. This study deals with simulation and implementation of DVR with open loop controlled systems. The hardware circuit of DVR was implemented.
