C. Levillain et Pg. Therond, MINIMAL PERFORMANCES OF HIGH-TC WIRES FOR COST-EFFECTIVE SMES COMPARED WITH LOW TCS, IEEE transactions on magnetics, 32(4), 1996, pp. 2308-2311
On the basis of a 22MJ/10MVA unit without stray field, we determine mi
nimal performances for High T-c Superconducting (BTS) wires, in order
to obtain HTS Superconducting Magnetic Energy Storage (SMES) competiti
ve compared with Low T-c Superconducting (LTS) ones. The cost equation
mainly considers the wire volume, the fabrication process and losses.
We then recommend HTS critical current densities and operating magnet
ic fields close to the present state of the art for short samples. A 3
0% gain for HTS SMES compared with LTS one could be expected.
