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.

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

Tests and recovery under load simulations of a novel bifilar resistive SFCL having undulated shape configuration

Superconductors Science and Technology, 2021
Power systems are becoming more interconnected and complex. The distributed generation expands and spreads across the grids, reducing the distance between the load and the generation.

Over-Critical Current Analysis for Helical SFCL Coil

2020 IEEE International Conference on Applied Superconductivity and Electromagnetic Devices (ASEMD), 2020
Superconducting fault current limiters (SFCLs) are foreseen to be critical and promising candidates in power system applications, due to their automatic fault current limiting performance, low loss, size compactness and light weight. A helical bifilar coil which is composed of one inner winding and one outer winding was developed, and these two ...

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.

Electromagnetic design of saturated iron core SFCL

2011 International Conference on Applied Superconductivity and Electromagnetic Devices, 2011
The most attractive advantage of a saturated iron core SFCLs (SIC-SFCL) is that its impedance can change from very low in normal power transmission to very high for fault current limiting. This characteristic is achieved by varying the electromagnetic states in the main body of the device, including the iron cores, the ac working coils, and the dc bias

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.

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 ...

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.
