“…R-SFCL has been modeled based on the relationship between electric field (E) and current density (J) (Aly & Mohamed, 2012) (Chen et al, 2013) (Sousa et al, 2012) (Blair et al, 2013) (Mafra et al, 2017) (Schettino et al, 2018) (Dondapati et al, 2017). According to this model, the superconducting material can be in one of three regions: superconducting, flux-flow, and resistive.…”

Fault current levels occurring in power systems force the breaking capacities of the breakers. In the power system elements, the generator, transformer, cables, etc., are exposed to the dangerous effects of fault current until the breaker clears the fault. Various limiting methods have been developed to eliminate this adverse situation in recent years. One of these methods is Superconducting Fault Current Limiters (SFCL). With the discovery of High-Temperature Superconductors (HTS), SFCL's Resistive type has become more popular. Resistive SFCL (R-SFCL), based on the non-linear resistance property of superconducting materials, limits the fault within the first half period. However, it cannot provide such a fast response after the fault. The time required to regain the superconducting state after the fault is the recovery time. For R-SFCL manufacturers, recovery time is a design parameter that must be kept short. This study examines limiting performance, recovery time, and voltage stability with the dynamic model created using MATLAB/Simulink. With the shunt breaker method proposed in the study, the recovery time was shortened, and the voltage stability improved.

The present paper introduces the main electric applications of superconducting materials, focusing on Superconducting Fault Current Limiters (SFCL). In recent years, short-circuit current values have increased, mainly due to a higher penetration of distributed generation. Fault Current Limiters (FCL) based on superconductor materials can provide one of the most promising solutions for limiting those fault currents. Nowadays, research focuses mainly on resistive SFCLs, because of size, cost and product maturity. Several modelling approaches for resistive type current limiters, as proposed in the literature, are reviewed hereby.

Superconducting fault-current limiters (SFCLs) have been the subject of research and development for many years and offer an attractive solution to the problem of rising fault levels in electrical distribution systems. SFCLs can greatly reduce fault currents and the damage at the point of fault, and help improve the stability of a power system. Superconducting fault-current limiters (SFCL) provide a new efficient approach to the reliable handling of such faults.(SCFLs) can be used for various nominal voltages and currents, and can be adapted to particular limiting characteristics in case of short circuits. In this project, dc resistive type superconducting fault current limiter (SFCL) is presented. This SFCL is designed for the HVDC system. Uniform current and voltage sharing among the SFCL modules can be observed through contact resistance tests, dc flow-through tests, and ac flow-through tests. Results of tests show that each limiting module has good uniformity in higher current system. The proposed concept can be implemented using renewable energy sources.The results are presented by using Matlab/Simulink platform.
