DVR with sweep mode control to alleviate voltage sags on a distribution system for three phase fault

Abstract

The point of common coupling voltage during sag condition resulting due to a fault occurring on the parallel feeder in a distribution system evidently shows good dynamic response of the DVR achieved through the sweep mode control. It can also be observed that usage of sweep mode control to DVR eliminates the additional sag detection and makes the DVR multifunctional, such as the same control can be used to compensate any variation in the supply voltage.
