Summary

Since 1999, a Japanese national project to realize commercially feasible SMES for designated applications has been promoted. Model coils of cost-reduction SMES for load fluctuation compensation and frequency control have been fabricated and tested. Performance testing was carried out for the multipole solenoid system, model coil utilizing forced cooling conductor stabilizing copper and separation CIC. Compared with the original design value, coupling loss was reduced to 1/50 or lower, thereby realizing extremely low current loss for a high-capacity large-scale conductor. A total of 10,000 repetitive energization tests were executed to confirm coil reliability. Effectiveness of the multipole was confirmed by measuring the leakage magnetic field. In addition, high-speed energization of 2 kA/s was achieved, confirming the possibility of expanding applicability to system stabilization. As a result, the authors verified that the cost reduction technologies including a conductor/coil manufacturing technology achieved the initial goal.
