Abstract High Tc Superconducting (HTS) DC cable is a promising solution for large-scale power transmission over long distance. However, the indispensable refrigeration system for HTS cable might be undesirable. Considering that LNG (liquid natural gas) now is one kind of clean energy that is used more widely and widely, it is possible to integrate the HTS cable and LNG transportation into an energy pipeline, resulting an acceptable new energy transportation system. In this paper, the principle and structure of the energy pipeline are discussed firstly, and then the basic physical properties of HTS tapes and liquid insulation media in LNG temperature range are analyzed. On the base as above, the general design of ±100 kV/1kA energy pipeline is made.

电力和LNG运输±100kV/1kA能源管道总体设计

摘要 高温超导 (HTS) 直流电缆是一种有前景的长距离大规模电力传输解决方案。然而，HTS 电缆必不可少的制冷系统可能并不理想。考虑到LNG（液态天然气）现在是一种应用越来越广泛的清洁能源，可以将HTS电缆和LNG运输整合到一条能源管道中，形成一个可以接受的新能源运输系统。本文首先讨论了能源管道的原理和结构，然后分析了高温超导胶带和液体绝缘介质在LNG温度范围内的基本物理性能。在此基础上，进行了±100 kV/1kA能源管道的总体设计。
