Analysis and simulation of superconducting magnetic energy storage system

Abstract

Subject field of the energy charging, storing and discharging characteristics of the Superconducting Magnetic Energy Storage system have been theoretically studied in the time to make an integrated mathematical model and the simulation model to analyses the characteristics of charging and discharging practically in Matlab. In this paper a novel controller is designed for controlling the Magnetic Energy storage system ensure (a) fast return of energy to the super­conducting coil under constant current mode and (b) a constant and sinusoidal input supply current irrespective of the varying load demand with and without harmonics. A special feature of this controller is its ability to smoothly charge the superconducting coil using constant current charging so that it can be ready for the next discharging operation as soon as possible. Matlab, Simulink is done under this paper with Matlab coding for generating the graph. The results suggest that the Theoretical and Simulink graph is approximately similar and with is the more simple Controller is designed for the Energy Discharging.
