Analysis on the Fusion Technology of a Commercial Transformer and an SFCL
Journal of Superconductivity and Novel Magnetism, 2012In this study, a new concept is proposed on a combination device with functions of a commercial transformer and a superconducting fault current limiter (SFCL). This device serves as a transformer by stepping the voltage up or down in normal condition.

Simulations of the Recovery Process of an Air-Coil SFCL
IEEE Transactions on Applied Superconductivity, 2016In this paper, a study of the recovery process of an air-coil superconducting fault current limiter (AC-SFCL) is done. Tests of an AC-SFCL prototype operating at normal conditions subjected to fault currents have been performed. After the interruption of the fault current, the system recovers its normal conditions in such a way that the recovery ...

2D and 3D Numerical Models of Inductive SFCL
IEEE Transactions on Applied Superconductivity, 2007The Superconducting Fault Current Limiter (SFCL) can be used to limit the short-circuit current level in electrical networks. The inductive SFCL works like a transformer with shorted secondary HTS winding. Because of the iron core, the inductive SFCL is not axially symmetrical and should be modeled in 3D geometry.

Earlier works have reported the emerging fault current limiter (FCL) segmentation technique to mitigate concurrent commutation failure (CF) under ac faults in multi-infeed LCC-HVDC systems. However, the FCL's parameter is determined by the electromagnetic transient (EMT) simulation based method, which will lead to enormous workload and long computation

Experimental Evaluation of AC Losses of a DC Restive SFCL Prototype
IEEE Transactions on Applied Superconductivity, 2010A DC resistive SFCL consists of an inductance and a quenching superconducting resistance embedded in diode bridge. The superconductor operates in nearly DC current conditions. This regime of operation drastically reduces the AC losses and makes it possible to implement the device by means of present state of the art superconductors.

Effect of a SFCL on Commutation Failure in a HVDC System
IEEE Transactions on Applied Superconductivity, 2013This paper describes an analysis of the effects of a superconducting fault current limiter (SFCL) on commutation failure in a high-voltage direct current (HVDC) system. Most commutation failures are caused by voltage disturbances at the inverter side and cannot be avoided in HVDC systems using thyristors.

Application Effects of SFCL in Korean Power System
IFAC Proceedings Volumes, 2003Abstract As power systems grow more complex and power demands increase, the fault current tends to gradually increase. In the near future, the fault current will exceed a circuit breaker rating for some substations, which is an especially important issue in the Seoul.
