Abstract

High-temperature superconducting (HTS) power cables with low loss and large capacity are playing an indispensable role in power transmission. However, the reliability analysis of in-grid HTS power cables is hindered by the scarcity of failure data from demonstration projects. This paper investigates the electromagnetic–thermal behavior of in-grid HTS power cables under two failure modes: short-circuit fault and cooling system failure. To improve the reliability of the HTS power cable, this paper proposes a current-dependent overheating protection strategy and a reclosure strategy based on the maximum self-recovery temperature. The optimized strategies increase the operating probability of the normal state for the HTS power cable from 99.27% to 99.49%, demonstrating that HTS power cables can achieve high reliability in grids.

基于电磁-热-水力分析的并网 HTS 电力电缆的运行可靠性

低损耗、大容量的高温超导（HTS）电力电缆在电力传输中发挥着不可或缺的作用。然而，由于缺乏示范项目的故障数据，电网内 HTS 电力电缆的可靠性分析受到阻碍。本文研究了电网内 HTS 电力电缆在短路故障和冷却系统故障两种故障模式下的电磁热行为。为提高 HTS 电力电缆的可靠性，本文提出了一种与电流相关的过热保护策略和一种基于最大自恢复温度的重合策略。优化后的策略将 HTS 电力电缆正常状态下的运行概率从 99.27% 提高到 99.49%，证明 HTS 电力电缆在电网中可以实现高可靠性。
