Abstract

The stability of the SMES model coil was investigated at the transport currents from 10 to 30kA and coolant temperatures of 4.5 and 6.0K. The initial normalcy was created by applying 20ms and 1kHz inductive heating pulse. Stability simulation was carried out by using numerical code POCHI, which was developed by JAERI. Since the simulation results are in good agreement with the experiment, the stability of the SMES conductor can be evaluated to be higher than current shearing temperature in the case of recovery. It can be concluded that the stability of the SMES conductor is sufficiently high. Furthermore, the stability of margin of the SMES pilot plant is calculated to be 830mJ/cm³ at the nominal point (20kA-4.5K). The SMES pilot plant is therefore expected to be stable for nominal operation.
