Analysis of AC loss and thermal stability of HTS model coils for 600 kJ SMES (superconducting magnetic energy storage).

Author(s) : PARK M., KWAK S., KIM W., et al.

Summary

A 600 kJ superconducting magnetic energy storage system project using high temperature superconductor (HTS) was initiated in 2004 and lead by Korea Electric Research Institute. HTS model coils are de-signed and manufactured for the preliminary test before we move to the full scale prototype. Reinforced BSCCO-2223 wire is used for magnet and the operating temperature is assumed to be 20 K. Even though the SMES is not an AC power device, time-varying current during the charging and discharging period leads to the time-varying magnetic field applied to the magnet and AC loss is generated. In this paper, AC loss and the temperature distribution of the model coils are analyzed and discussed.
