A Novel Control Scheme for Sag Mitigation Using DVR

Smruti Meshram, S.K. Umathe


This paper gives course of action of modeling & analysis of DVR for improving power quality. This device is one of the power electronic device used in distribution system to protect consumers against sudden changes in voltage magnitude. It is able to maintain load voltage within determined value. Several configuration & control means are planned for this device. This paper gives the general idea of DVR, its role, design, mechanism, reimbursement strategies & direct process are evaluated besides device capabilities & limitations. Also the study of PLL design for the inverter grid connection
