Superconducting fault current limiter is an attractive electronic device to solve the problem of very high fault current in the power system. In this paper, the performance of enhanced system capacity with existing switchgear by superconducting fault current limiter is studied. At first, a resistive type SFCL is modeled in Simulink. A three phase system with a nominal capacity is designed and then it is replaced by higher capacity keeping switchgear unchanged. Finally, the SFCL is introduced in the higher capacity system. Fault current in this system is limited by SFCL to the level of the presented switchgear. Thus, it is revealed that the outstanding current limiting performance of SFCL can be used to limit the fault to the level of the existing switchgear if the system capacity is improved.

“…The SFCL responds before the first cycle peak and provides effective means to limit excessive fault currents to safe levels without the disadvantages of conventional fault current mitigation methods. Present researches on fault current limiters focus on resistive type [2] and inductive type [3][4][5][6][7][8][9][10][11]. The drawback of the concept of inductive limiter with shielded core was insertion of a finite impedance in the line even during normal operation, and the large size and weight of the iron core [7,10].…”

Superconducting fault current limiters are the most attractive devices for the power network, they can be used to limit the short current in electrical network. The operation of a superconducting fault current limiter is based on the sudden transition from the superconducting state to the normal state by exceeding the critical current Ic of the material. This transition one takes a very short time, so fast that we are able to limit the first current peak to a threshold value which does not exceed three to five times the rated current. This paper presents the design, the calculated electrical parameters and tests of the medium voltage class superconducting fault current limiter prototypes made in Electrotechnical Institute. The constructed coreless superconducting fault current limiter consists of three windings: ones made of SF12050 tape and a parallel connected primary copper winding. All windings are inductively coupled and intended to work in liquid nitrogen.

“…Resistive superconducting fault current limiters (RSFCLs) can be used to maintain the level of short-circuit current in power networks below a certain safety margin [1]. High-temperature superconducting coated conductors (HTS-CCs) are good candidates for RSFCL applications because of their high critical current and their ability to switch from superconducting state to a high resistive state in a short time.…”

High-temperature superconducting coated conductors (HTS-CCs) are good candidates for resistive superconducting fault current limiter (RSFCL) applications. However, the high current density they can carry and their low thermal diffusivity expose them to the risk of thermal instability. In order to find the best compromise between stability and cost, it is important to study the heat transfer between HTS-CCs and the liquid nitrogen (LN 2 ) bath. This paper presents an experimental method to monitor in real-time the temperature of a quenched HTS-CC during a current pulse. The current and the associated voltage are measured, giving a precise knowledge of the amount of energy dissipated in the tape. These values are compared with an adiabatic numerical thermal model which takes into account heat capacity temperature dependence of the stabilizer and substrate. The result is a precise estimation of the heat transfer to the liquid nitrogen bath at each time step. Measurements were taken on a bare tape and have been repeated using increasing Kapton ® insulation layers. The different heat exchange regimes can be clearly identified. This experimental method enables us to characterize the recooling process after a quench. Finally, suggestions are done to reduce the temperature increase of the tape, at a rated current and given limitation time, using different thermal insulation thicknesses.
