Temperature Dependent Equivalent Circuit of a Magnetic-Shield Type SFCL

IEEE Transactions on Appiled Superconductivity, 2005
In order to investigate the reciprocal interaction between a SFCL and the Power System an equivalent circuit of the device needs to be introduced in a power system simulator. In this paper the equivalent circuit of a magnetic shield type SFCL, consisting of two coupled electric and thermal networks, is obtained starting from the integral formulation of

Superconducting fault current limiter (SFCL): Experiment and the simulation from finite-element method (FEM) to power/energy system software

Energy, 2021
The superconducting fault current limiter (SFCL) has been regarded as one of most popular superconducting applications. This article reviews the modern energy system with two major issues (the power stability and fault-current), and introduces ...

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).

Characterization of reactors for integrated matrix-type SFCL

Physica C: Superconductivity and its Applications, 2011
Abstract We reported the fabrication and analysis of the reactor for matrix-type superconducting fault current limiters (SFCLs). Reactors take a role of inducting magnetic field to superconductors in reactors and bypassing partial fault currents to themselves. Superconductors used in this work were YBCO thin films deposited on 5.08 cm diameter Al 2 O

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

Design and Characterization of the Integrated Matrix-Type SFCL

IEEE Transactions on Applied Superconductivity, 2009
In this paper, we report the improved and integrated matrix-type superconducting fault current limiter (MFCL). The new MFCL proposed in this work has a structure that easily improves the quench characteristics of superconducting elements. This integrated MFCL is simply constructed by mounting a trigger element and superconducting elements in a single ...
