Abstract
In pursuit of high efficiency of energy conveying system, a new high temperature superconducting electric power transmission system cooled by LNG (liquefied natural gas) is investigated. LNG is used to contribute a low temperature environment for the superconducting cable operated in the temperature range of 85-95K. On the basis of previous research, the new structure of the combined transmission system consists of a flowing channel for sub-cooled LN2 (liquid nitrogen) as a kind of protective medium. In this paper, the remarkable advantages of the combined transmission system are demonstrated through the analysis. Comparison of efficiencies in different operation condition has been conducted. The results showed that the new system is of great significance for the high efficient transmission of energy.
