Feasibility of inline cooling in long distance HTS power line

摘要

Based on the most recent HTS cable projects worldwide, we discuss the possibility of making long liqui nitrogen cooled HTS lines. We use the concept of inline cryocoolers to achieve cables of infinite lengtl We model the cable temperature and pressure distribution and determine the cooling power neede per cryocooler as a function of the desired cable unit length. Repetition of this cable unit, including cryc cooler and pumps, makes it possible to achieve cables of infinite length and opens the route to comple HTS power grids.
