超导输电电缆被认为是实现大容量、高效率的下一代电力系统的关键，4 mm涂层导线已被广泛用作发展超导电缆的标准。最近的研究表明，与标准的4 mm涂层导体相比，2 mm窄涂层导体在降低超导电缆交流损耗方面具有明显的优势。此外，多亏了激光切割技术，可以将宽涂层导体切割成小到2毫米的带子，而不会造成太大的损害。因此，2 mm窄涂覆导线受到越来越多的关注，成为发展更高效超导电缆的一种潜在选择。到目前为止，关于由4 mm覆层导体组成的超导电缆的交流损耗特性已经有了很多讨论，而对于由2 mm窄覆层导体组成的超导电缆的研究却很少。本文旨在阐明由2 mm窄涂覆导线组成的超导电缆的交流损耗特性，特别是分析交流损耗与层数的关系，旨在研究多层结构对这类电缆交流损耗的影响。应用二维有限元方法建立了一套模拟这种超导电缆的数值模型。这套模型包括1层、2层、4层和6层电缆，前三种类型的电缆是正在开发的实际电缆，最后一种是未来的选项。所有电缆均选用具有相同临界电流和电流分布的2 mm窄涂覆导线。在这些电缆中，进行了数值电磁场分析，以进行交流损耗计算和比较。
Superconducting power transmission cables are regarded as a key to realize the next-generation power systems with high capacity and high efficiency, and 4 mm coated conductors have been broadly used as a standard to develop such cables. Recent research shows that, comparing with standard 4 mm coated conductors, narrow 2 mm coated conductors prove to have a pronounced advantage on AC loss reduction for superconducting cables. Besides, thanks to laser cutting technique, it became possible to cut wide coated conductors into small tapes as narrow as 2 mm without considerable damage. Hence, narrow 2 mm coated conductors are attracting more and more attentions and have turned into a potential option for developing more efficient superconducting cables. So far, there have been many discussions on AC loss characteristics of the superconducting cables consisting of 4 mm coated conductors, whereas, the studies on cables comprising narrow 2 mm coated conductors are very few. This paper is to clarify the AC loss characteristics of superconducting cables consisting of narrow 2 mm coated conductors, especially to analyze the dependence of AC loss on the number of layers, with the intention of studying the effect of multilayer configuration on AC losses of such cables. A set of numerical models simulating such superconducting cables have been developed by applying 2-D FEM method. This set of models comprises 1-layer, 2-layer, 4-layer and 6-layer cables, with the former three types of cables as practical cables under development and the last one as a future option. Narrow 2 mm coated conductors with the same critical current and current distribution were selected for all the cables. Within these cables, numerical electromagnetic field analysis has been carried out for AC loss calculation and comparison.
