Abstract: 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.
