HARMONICS REDUCTION IN DISTRIBUTION GRID USING DVR

Abstract

Harmonics generated by non-linear critical loads are major anxiety for the
industries. This paper proposes a method for dynamic voltage restorer (DVR)
to limit voltage harmonics. DVR is a well-known a commercially available,
popular device to eliminate voltage sags and swells in the distribution lines.
Close loop control for DVR and a distribution grid of Vinh Phuc province are
modeled and simulated using Matlab software. The simulation results of
Vinh Phuc province distribution grid are presented to demonstrate the
effectiveness of the proposed DVR system.
