Abstract

A 10 kV High Temperature Superconducting power substation with a cooling system was developed and has been put into operation in power distribution system for more than three years. The working conditions, heat resource and the distribution character of the four apparatuses working at the 10 kV/630 kVA HTS substation were analyzed. The heat load is distributed along the length for the cable for which thus a forced enclosed circulation system is necessary; while it is concentrated within only several cryostats for the other three HTS apparatus for which it is enough to cool only with an opened loop cooling system by consuming of liquid nitrogen. And an independent cooling system with refrigerator for the 1 MJ SMES is a good selection due to the different working temperature range. Based on the analysis and discussion, a concentrated evaporative cooling station which includes an opened loop cooling system without circulation and a forced circulation system with a closed circle was designed and constructed.
