Abstract :
In this paper, a design methodology for toroid-type superconducting magnetic energy storage system using the analytical method and data table from finite element analysis is proposed. The method simplifies the model, and uses analytically derived equations to calculate the energy and center flux density. In order to determine the number of turns and current using the analytic process, perpendicular flux density and parallel flux density are obtained from the data table. A 2.5-MJ toroid-type superconducting magnetic energy storage system is designed using the proposed method.
