Abstract

Dynamic Voltage Restorer is a custom power device used in electrical distribution system for power quality improvement. The main application of it is for voltage compensation of sensitive loads against voltage disturbances such as voltage sag and voltage swell in distribution lines. It is a series connected device and is able to compensate voltage sag and voltage swell by injecting a voltage with the help of series injection transformer. Conventionally, Dynamic Voltage Restorer consists of an energy storage device which supplies the required power over the limited duration of the sags through an inverter.
