Outline of Final Research Achievements |
To realize a low-carbon society, it is urgent to develop a power generation and storage energy system using high temperature superconducting coils. However, the high temperature superconducting coil has a disadvantage of burning out due to thermal runaway, and it is very difficult to detect it Therefore, in this research, we aimed to search for protection guidelines for thermal runaway of high temperature superconducting coils. In this research, as element development, we set up a numerical calculation system for thermal electromagnetic analysis in high-temperature superconducting coils, developed a method for measuring characteristics of high-temperature superconducting tapes. We fabricated a high temperature superconducting thin film to increase the current capacity of high-temperature superconducting coils.
