Superconducting Fault Current Limiter

The inductive-type superconducting fault current limiters (LSFCLs) mainly consist of a primary copper coil, a secondary complete or partial super-conductor cylinder & open magnetic iron core. Complete performance of these devices significantly depends on the optimal selections of its materials and dimensions of construction, electrical, magnetic, thermal, and parameters. It is important to identify a comprehensive model describing the characteristics of LSFCL in a power system prior to its fabrication. When any fault occurs, the dynamic model will characterize the overall phenomena to compare the simulation results by varying LSFCL parameters to maximize the merits of a FCL while minimizing its drawbacks. The principle object of this paper is to achieve a full penetrative approach of design of LSFCLs by means of multi criteria decision-making techniques.
