Abstract
A solenoidal-type superconducting magnetic energy storage (SMES) using ferromagnetic material as an exterior magnetic circuit can store abou t 30% more magnetic energy than that using no ferromagnetic material. The amount of pure iron needed is 3.4 ton/MJ or 12 000 ton/MWH for the operating magnetic flux density of the solenoid between 4 and 5 T. Lo w grade ferromagnetic material containing more than 50% pure iron may be available for the SMES.
