A power distribution system to be used on a 5 GW space power station (SPS) is described. The system uses a low voltage dc superconducting cable (SC) to transport electric power 4 kV 10 kA of electric power from the solar collectors to the converting system. The maximum current of the collection system is determined by minimizing the summation of Joule losses and the refrigerating load. The cable is made of aluminum stabilized NbTi, and the negative and positive conductors are laid coaxially to suppress the magnetic field outside the cable. It is shown that the SC system provides greater efficiency and lower lift-off weight to the station in comparison with conventional cable systems. A cross section of the SC is shown. 5 references.
