Enhancing Power Quality with improved Dynamic Voltage Restorer

[摘要] This paper describes the enhancement of power quality with improved DVR technology. Requirement of Power Quality (PQ) is one of the most important issues for power system. There are different methods to compensate the voltage sags and swells, one of the most popular methods of sags and swells compensation is Dynamic Voltage Restorer . DVR provides advanced and economic solution to compensate voltage sags and swells. This device can be implemented to protect a group of medium or low voltage consumers. This study present compensation of sags and swells voltage during single line to ground and three phase faults. By using DVR technology, power quality enhances, which is shown in simulation waveform.
