“…There are several types of FCLs which all of them, insert a high impedance during fault conditions and a low impedance in normal operating situations of the system, such as: power electronics [39], resonance circuits [40] and superconducting materials [41][42][43][44][45].…”

“…Furthermore, in order to increase the power ratings of the SFCL, a lot of superconducting elements should be connected in series and in parallel, which resulted in extreme high cost. In order to solve these problems, the hybrid SFCL was proposed [1][2][3][4][5][6][7][8][9][10][11].…”

-The application of large power transformer into a power distribution system was inevitable due to the increase of power demand and distributed generation. However, the decrease of the power transformer's impedance caused the short-circuit current of the power distribution system to be increase thus, the higher short-circuit current exceeded the cut-off ratings of the protective devices such as circuit breaker. To solve these problems, several countermeasures have been proposed to protect the power system effectively from higher fault current and the superconducting fault current limiter (SFCL) has been expected to be the promising countermeasure. In spite of excellent current limiting performances of the SFCL, on the other hand, the efforts to apply the SFCL into power system has been delayed due to both the limited spaces for the SFCL's installation and its long recovery time after the fault removal. In order to solve these problems, a hybrid SFCL, which can perform either first half cycle limiting of first half cycle non-limiting operation, has been developed by corporation of LSIS (LS Industrial System) and KEPCO (Korea Electric Power Corporation). In this paper, we tried to requirements hybrid SFCL by PSCAD/EMTDC. Simulation results of our analysis of the hybrid SFCL is that its accompanied the characteristics both the limit the fault current and quick recovery caused by the less impact from superconductor.

“…The inductive limiter limits the fault current by introducing a suitable inductance in the faulted circuit, whereas a resistive limiter achieves the function by introducing a resistance [7][8][9][10]. The 35kV/90MVA saturated iron-core superconducting fault current limiter (SICSFCL) is an inductive SFCL with an active control of the dc magnetization circuit.…”

A cryogenic system was built as an open system for a 35kV/90MVA saturated ironcore superconducting fault current limiter. It consists of an annular cylindrical liquid nitrogen dewar, cryogenic pipes, sensors, valves, and a control unit. A HTS dc bias coil was immersed with liquid nitrogen in the dewar. The control circuit constantly monitors the liquid nitrogen level and controls the supply of liquid nitrogen in accordance with the liquid nitrogen level change. Nitrogen vapor was directly released into the environment. Heat loss under different working conditions, such as no magnetization current, 150 A magnetization current, and on-grid condition, was measured to evaluate the performance of the system. As compared with no magnetization current of the dc bias coil, evaporation of liquid nitrogen increases about 20% under the on-grid condition.
