Abstract
Our experimental SMES of 1kWh/1MW named “ESK” (Experimental SMES of Kyushu Electric Power Co., Inc.) is going to be completed in 1997. It has a toroidal coil system with 6 elementary coils (~ each 1/6 kWh) made by 3 manufactures independently, each of which has its own type of coil and conductor: Compacted Rutherford type for conductors, and pancake and layer-winding type for coils. The newly designed coil shape “modified D” has two straight parts in-between D parts.
Measurements were made for each of the 3 coil types in the 6 elementary coils. The results are: coils were stable up to the current corresponding to the rated 1000A of the toroidal arrangement. Losses were measured for the condition of repeated charging and discharging with high ramp rate were within the designed value. Strains have also been measured on the support structures of each coil, mechanical characteristics of each coil are compared.
