Modelling and analysis of resistive Superconducting Fault Current Limiter

Abstract

Superconducting Fault Current Limiters (SFCLs) are used in power system network to mitigate the overcurrent and its prominent effects. Nowadays, Coated Conductors (CCs) are widely used for novel design of SFCL for such applications. In this paper, comparative study on the operational characteristics of Resistive-SFCL based on BSCCO and YBCO Coated Conductors under fault condition is analyzed for an 110kV/9kA network. Also Electro-thermal Model of Coated Conductor is studied in MATLAB software. To verify the effectiveness of the proposed Resistive-SFCL, several case studies of Coated Conductors have been carried out in MATLAB. The results show the choice of optimal configuration of CCs as SFCL which effectively improves the thermal stability and current limiting characteristics under fault condition in the network.
