Enhancing the DC Voltage Quality in EV Charging Station Employing SMES and SFCL Devices

IEEE transactions on applied superconductivity, 2021
The fast-response energy compensating feature from a superconducting magnetic energy storage (SMES) device is favored for suppressing instantaneous voltage fluctuations, while the self-triggering current limiting feature from a superconducting fault ...

Recovery Characteristics of GdBCO Series-Connected Non-Inductive Coil in Pressurized Liquid Nitrogen for a Resistive SFCL

IEEE transactions on applied superconductivity, 2021
A SFCL (Superconducting Fault Current Limiter) is expected to limit a fault current and to improve system stability and operation flexibility in electric power system which is becoming more and more complicated and larger-scale. In order to put SFCL into

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.

2D and 3D Numerical Models of Inductive SFCL

IEEE Transactions on Applied Superconductivity, 2007
The 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.

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

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

Application Effects of SFCL in Korean Power System

IFAC Proceedings Volumes, 2003
Abstract 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.

Experimental Evaluation of AC Losses of a DC Restive SFCL Prototype

IEEE Transactions on Applied Superconductivity, 2010
A 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.

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).

A new type of superconducting fault current limiter (SFCL)

IEEE/PES Transmission and Distribution Conference and Exhibition, 2003
The superconducting fault current limiter (SFCL) is one method to solve the conflict between the rated value of breaker and fault current. Unfortunately, all types of SFCL currently available are too expensive to be used in electric power systems. Moreover, some types of SFCL need long time to recovery from quench condition, which adds difficulty on ...
