Impact of Dynamic Voltage Restorer (DVR) on Reliability Improvement of Distribution System Sensitive Loads

Voltage sag is one of the most important power quality problems which occurs frequently in distribution systems and cause production loss in voltage sensitive customers. Due to voltage sags the reliability of distribution system decrease severely from the view point of these customers. Custom power devices are the most famous compensators in distribution systems. Among these devices Dynamic Voltage Restorer (DVR) is known as a cost /effective voltage sag compensator
