Development and tests of superconducting magnetic energy storage systems components

The major components of a superconducting magnetic energy storage system are briefly discussed. The electrical parameters of such a system are derived for constant power operation during magnet charging and discharging. A circuit to evaluate high current superconductors economically and nondestructively is described and test results for three different wires are presented. The second half of the paper deals with the design of an automated model SMES system which operates in a closed-loop power control mode. Test results of a twelve-pulse converter loaded with a pure inductance are given.
