Abstract

For quite a long time many research and developments of superconducting magnetic energy storage (SMES) system have been doing for the enhancement of power quality control of a sensitive electric load. Korea Electrotechnology Research Institute (KERI) has developed a 3MJ, 750 kVA SMES system to improve power quality in sensitive electric loads. This paper describes the design, fabrication and experimental results for the 3MJ SMES magnet made by using the design code of a SMES device that we developed. A computer code was developed to find the parameters of the SMES magnet, which has a minimum amount of superconductor for the same stored energy. And the 3MJ SMES magnet was designed based upon those. In addition, the 3MJ SMES magnet that was ramp up to 1kA without quench.
