| Outline of Final Research Achievements |
We investigate a Superconducting Fault Current Limiting Cable (SFCLC), which is an HTS cable with fault current limiting function. We investigate the influence of the longitudinal temperature distribution on current limiting function and temperature rise after the current limitation of SFCLC. We suggested the effective measures of parameter control to achieve both the higher current limiting function and the lower temperature rise.
And, from the viewpoint of the fault current limitation coordination in a power transmission system, it is necessary to investigate the interaction of current limiting functions between multiple SFCLCs introduced in the system. In the model power system, two SFCLCs were connected in parallel and two fault points were assumed. In the substantially parallel connection, each SFCLC operates as the case of single SFCLC introduction. In the substantially series connection, the current limiting effect is determined by SFCLC with the smaller critical current.
