“…Despite more than 30 years of history in the development of superconducting (SC) fault current limiters (FCLs) and other devices based on the superconducting-normal state transition (S-N transition), the number of papers and projects devoted to the topic are not exhausted [1][2][3][4][5][6]. The first prototypes of SC FCLs were based on low-temperature superconductors (LTS) [7][8][9].…”

“…The progress in the fabrication technology of large diameter (40-50 cm) HTS rings and hollow cylinders [13,14] stimulated their application as secondary one-turn shortcircuited SC windings of the inductive FCL. Based on these cylinders, different experimental models of FCLs [3,6,[15][16][17] and current-limiting transformers [5,18] were built with the purpose to prove the feasibility of concepts and to study the device operation in power systems.…”

We reveal obstacles related to the application of HTS cylinders in current limiting devices based on the superconducting–normal state transition. It is shown that, at the critical current density achieved presently in bulk materials, and especially in BSCCO-2212, the required thickness of the cylinder wall in a full-scale inductive device is several centimetres. A simple mathematical model of the operation of an inductive fault current limiter (FCL) is used to show that such cylinders cannot be cooled in an admissible time after a fault clearing and, hence, the inductive FCLs and current-limiting transformers employing BSCCO cylinders do not return to the normal operation in the time required. For the recovery even with a non-current pause in the circuit, cylinders are needed with a critical current density an order of magnitude higher than the existing one.

“…Under specific conditions, employing resistive-type SFCLs can be advantageous for enhancing the transient stability of power systems [10][11] . Inductive SFCLs have also been widely considered [12][13][14] , and have some distinctive merits, including large design flexibility owing to the turn ratio, separation of the current-limiting device from the power transmission line [15] , and low heat loss owing to its very low resistance [16] . A flux-coupling type SFCL has been proposed by our research group [17][18] , corresponding to an inductive and In the normal condition, the switch S 1 is closed, and the SFCL is in the zero-resistance/ superconducting state.…”

：A modified flux-coupling type superconducting fault current limiter (SFCL) is proposed here for suppressing fault currents. The modified SFCL consists of a coupling transformer, an yttrium barium copper oxide (YBCO) pancake coil, and a controlled switch. By flexibly adjusting the controlled switch's contact states based on the system operational conditions, the coupling transformer's primary inductance as well as the YBCO coil's normal-state resistance are incorporated into the main system for current limitation. Because the modified SFCL has the advantages of resistive and inductive SFCLs, it may improve the power system's transient behavior. Hence, the SFCL's effect on the transient stability of a multi-machine power system was also theoretically investigated. Further, simulations were conducted for accessing the SFCL's performance characteristics under different fault conditions. The results show that using the proposed SFCL can effectively restrain the increased fault current and improve the bus voltage sag; meanwhile, the imitated multi-machine system's power-angle oscillation can be obviously reduced.
