Abstract

The European project SCARLET is dedicated to advancing the integration and application of superconducting technologies for medium voltage direct current (MVDC) systems. One of the main innovations within SCARLET is the development of a dual-purpose infrastructure that combines the transmission of bulk electricity and liquid hydrogen. The MgB ₂ superconducting cable, operating at around 20 K, finds its suitable environment within the pipeline for liquid hydrogen transport. This integration promises a compact and economically attractive solution for the simultaneous distribution of hydrogen and electricity. In this paper, we present various designs of the MgB ₂ cable core, showcasing results from electro-thermal simulations and highlighting the strengths and potential challenges. The intent of this work is to help identify the most effective cable configuration that meets the requirements of energy efficiency and compactness, while also considering the constraints associated with the production phase. In addition, to enhance the sensitivity to the thermal behaviour, a thermal model was developed and presented.

1gw超导输电MgB2电缆布局的比较分析——来自SCARLET项目的见解

欧洲项目SCARLET致力于推进中压直流（MVDC）系统超导技术的集成和应用。SCARLET的主要创新之一是开发了一种结合大容量电力和液氢传输的双重用途基础设施。MgB2超导电缆在20 K左右工作，在管道内找到了液氢输送的合适环境。这种集成保证了氢和电同时分配的紧凑和经济上有吸引力的解决方案。在本文中，我们介绍了MgB2电缆芯的各种设计，展示了电热模拟的结果，并强调了其优势和潜在的挑战。这项工作的目的是帮助确定最有效的电缆配置，以满足能源效率和紧凑性的要求，同时也考虑到与生产阶段相关的限制。此外，为了提高对热行为的敏感性，开发并提出了一个热模型。
