Abstract

The study of a 50-kWh Swiss superconductive magnetic energy storage model is in progress to demonstrate the feasibility of a 1-MWh prototype concept. A preliminary discharge performance analysis of this model has shown that, assuming a rectangular pulse at full power (1 MW for 154 s), the total heat load due to AC losses in the complete coil is 90 W. Following a single discharge pulse, the maximum conductor temperature is 5.3 K at the outlet of the 1035 m long hydraulic channel (0.6 K due to AC losses, 0.3 K due to throttling). A continuous coil operation may be performed with dead times between pulses ⩾7-20 min., depending on the effective temperature margin
