The 15 kV Class Inductive SFCL

IEEE Transactions on Applied Superconductivity, 2010
The Superconducting Fault Current Limiter (SFCL) is one of the most attractive devices for the electrical power network. The inductive SFCL consists of two coaxial windings and an optional magnetic core. The primary winding, connected in series to the circuit, is conventionally made of the copper wire, the secondary is made of a superconductor.

Transient Voltage Propagation in Bifilar Coils of a 380 kV Resistive Type SFCL

IEEE transactions on applied superconductivity
Resistive type superconducting fault current limiters (R-SFCLs) are currently developed up to an operating voltage of 220 kV and higher voltage levels seems to be necessary in the future.

Conceptual design and simulation of a thermal matrix-type SFCL

Superconductors Science and Technology
Simultaneous quench is a prerequisite for achieving high-rated voltage and current in superconducting fault current limiters (SFCLs) based on superconducting thin films. In this article, we propose the T-MSFCLs, i.e.

Further study of a novel inductive SFCL for multiterminal HVDC systems

Superconductors Science and Technology, 2021
Multiterminal high voltage direct current (HVDC) systems are developing rapidly lately. However, the high rising rate of fault current and the lack of interrupting capacity of the available DC circuit breakers hinder the further development of ...

Transient Simulations of an Air-Coil SFCL

IEEE Transactions on Applied Superconductivity, 2014
Simulations of superconducting fault current limiters (SFCL) devices become more crucial in order to predict their behavior before installing them into power systems. There are different approaches for modeling SFCLs, whereas computational simulations provide a better understanding of the behavior of SFCL devices.

Effects of Lamination Thickness on Recovery Characteristics of a Variable Resistance SFCL

IEEE transactions on applied superconductivity
Resistive type superconducting fault current limiter (R-SFCL) can be used to suppress the fault current with low loss in normal conditions and fast response time in fault conditions. To meet the demand of reclosing, the fast recovery is required. However,

Combined Effect of the SFCL and Solenoid Coils

IEEE Transactions on Applied Superconductivity, 2014
As the capacity of power facilities increases with the power demand, the fault current also increases in the case of a power system fault. Many studies are underway to limit the increasing fault current. They especially include superconducting fault current limiters (SFCLs).

Cooperative Control of SFCL and SMES-Battery HESS for Mitigating Effect of Ground Faults in DC Microgrids

IEEE transactions on applied superconductivity, 2021
DC fault is one of the most important and critical challenges for stable operation of DC microgrids. Resistive type superconducting fault current limiter (R-SFCL) is an ideal protective solution to limit DC fault current.
