Oil/gas plant is one of largest electrical energy consuming facilities, and its electric power distribution network must have high reliability, high efficiency, and, in certain locations, more efficient space utilization. Superconducting cable offers one of the most effective solutions to meet these requirements. However, application of superconducting cable to such a plant has not been reported. In this paper, the static and dynamic performance of a superconducting cable applied to a typical distribution substation feeding an oil/gas planet is investigated. The voltage distribution under steady state operation and the transient voltage and current during fault conditions are examined and compared with conventional cables. It is found that, in addition to improving efficiency, the superconducting cable can be applied without further constraints on circuit breaker duties and insulation coordination requirements. Furthermore, a typical electric power network in the plant is proposed.
