Physical Field Modeling Research on the Monitoring System of High-Temperature Superconducting Cable Channels

高温超导电缆作为新型电力传输技术的典型代表，其安全稳定运行在很大程度上依赖于其所在电缆通道的完好状态，因此实时监测电缆通道成为确保系统可靠运行的关键。然而，传统监测方法主要依赖于定期巡检和离线数据分析，存在响应延迟、数据采集不全面以及预警不及时等不足，难以满足现代电网对监测精度和实时性的严苛要求。为应对此挑战，文章基于物理场仿真技术，深入设计并构建了电缆监测系统的关键模块，重点开发了电缆通道多物理场仿真模型。通过与历史检测数据的对比分析，验证了所构建物理场仿真模型在电缆通道状态监测中的有效性。该研究为高温超导电缆的实时、智能监测提供了一种创新性解决方案，并为推动电网监测技术向更高智能化和数字化方向发展奠定了坚实的理论基础和工程实践依据。High-temperature superconducting cables, as a novel power transmission technology, largely depend on the intact condition of their cable conduits for safe and stable operation. Real-time monitoring of these channels is, therefore, key to ensuring reliable system performance. However, traditional monitoring methods, which mainly depend on periodic inspections and offline data analysis, suffer from delayed responses, incomplete data acquisition, and untimely warnings, making it difficult to meet the stringent requirements for monitoring accuracy and real-time performance in modern power grids. To address this challenge, this paper employs physical field simulation technology to design and construct the critical modules of a cable monitoring system, with a particular focus on developing a multi-physics simulation model for cable channels. Through comparative analysis with historical detection data, the effectiveness of the developed physical field simulation model for monitoring the status of cable channels has been validated. This study provides an innovative solution for the real-time, intelligent monitoring of high-temperature superconducting cables and lays a solid theoretical foundation and practical engineering basis for advancing power grid monitoring technology towards higher levels of intelligence and digitization.
