Compensation of Distribution System Voltage Sag by using SMES based DVR

M Maga Rathi Rathi, E. Parimalasundar

Abstract

Voltage sag is the most common type of power quality disturbance in the distribution system. This paper presents Superconducting Magnetic Energy Storage (SMES) based Dynamic Voltage Restorer (DVR) has the potential to bring real power storage characteristic to protect consumers from the grid voltage fluctuations. Due to the characteristic of high energy density and quick response, a superconducting magnet is selected as the energy storage unit to improve the compensation capability of DVR. The principle of Superconducting Magnetic Energy Storage based Dynamic Voltage Restorer is analyzed in this paper. The performance of the Superconducting Magnetic Energy Storage is validated through simulations using MATLAB SIMULINK.
