Storing power for critical loads
Article Abstract:
Companies are increasingly using superconducting magnetic energy storage (SMES) in place of traditional systems for backup power as smaller SMES systems are developed. SMES systems use magnetic fields produced by current flowing in superconducting coils to store energy. The systems keep the coils at the proper temperature for superconductivity via a cryogenic fluid. The high power-delivery rate of SMES is virtually independent of its storage capacity, so SMES is better than other systems for the short voltage sags and momentary power interruptions that have become more common since utilities' use of automatic reclosers has increased the incidence of momentary disturbances. SMES can also have a large number of highly efficient charge-discharge cycles, great power, no loss of services or products, no cleanup and no repairs. SMES does, however, have a strong magnetic field fringe that can be a liability for some companies.
