Installation and Testing of SFCLs

IEEE Transactions on Applied Superconductivity, 2012
A 22.9 kV/630 A-class superconducting fault current limiter (SFCL) was installed on a distribution line in Icheon Substation for real-grid operation. The substation is located in a semi-urban area with moderate loads. The SFCL is of hybrid type. After installation it was subjected to a series of on-site tests.

Comparative Study of Active SFCL and Resistive type SFCL on a Nine Bus System

2018 International Conference on Computing, Power and Communication Technologies (GUCON), 2018
With the increasing load demand and interconnection of distributed generations, there has been a significant rise in short circuit current levels in transmission as well as in distribution networks. The increment in fault current has imposed burden on the existing system equipments and also cause system instability.

Increase of Current Limiting Capacity of SFCLs by Using Matrix-Type SFCL Module

IEEE Transactions on Applied Superconductivity, 2011
We report the increase of the current limiting capacity of SFCLs by using the basic 1 × 3 matrix module with 3 superconducting elements. To do this, we fabricated the basic superconducting module with the 1 × 3 matrix structure which consists of a trigger part and current limiting parts.

Comparison of Inductive and Resistive SFCL

IEEE Transactions on Applied Superconductivity, 2013
This article presents a comparison of inductive and resistive superconducting fault current limiter built with the same length of high temperature superconducting (HTS) tape. The resistive limiter is constructed as a noninductive bifilar winding. The inductive coreless limiter consists of primary winding and secondary shorted winding. Both limiters are

The ADI Method for Simulations of SFCL

IEEE Transactions on Applied Superconductivity, 2015
In spite of the recent advances achieved with superconducting fault current limiters, modeling and simulation of such devices are still important issues. Different approaches have been used to model the transient behavior of such devices when submitted to fault currents.

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 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.

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).
