Comparison between resistive and inductive superconducting fault current limiters for fault current limiting

2012 Seventh International Conference on Computer Engineering & Systems (ICCES), 2012
Superconducting fault current limiters (SFCLs) are used to limit the short-circuit current level in electrical transmission and distribution networks. Applications of SFCLs would not only decrease the stress on network devices, but also can offer a connection to improve the reliability of power system.

Fault Current Limitation Coordination in Electric Power Grid With Superconducting Fault Current Limiters

IEEE Transactions on Applied Superconductivity, 2018
This paper proposes the concept of “fault current limitation coordination” in a future electric power grid with multiple superconducting fault current limiters (SFCL). Not only the fault current limitation of each SFCL on a transmission line, but also the transient stability of the grid with SFCLs should be taken into account, because the disturbance ...

Superconducting fault current limiters

IEEE Power Engineering Review, 2000
Events in the power utility industry, such as deregulation, demands for better power quality and reliability, the advent of high temperature superconductivity, and the push to use technology to realize greater profits, have renewed interest in fault current limiters (FCL).

DC superconducting fault current limiter

Superconductor Science and Technology, 2006
There is a lack of satisfying solutions for fault currents using conventional technologies, especially in DC networks, where a superconducting fault current limiter could play a very important part. DC networks bring a lot of advantages when compared to traditional AC ones, in particular within the context of the liberalization of the electric market ...

Electromagnetic fault current limiter

Electric Power Systems Research, 1997
Abstract Due Due to electrical power system expansion, utility systems are faced with fault currents higher than the momentary and interrupting capabilities of the equipment installed. One method to solve the problem is to use a fault current limiter.

Fault current limiters using superconductors

Cryogenics, 1997
Fault current limiters on power systems are to reduce damage by heating and electromechanical forces, to alleviate duty on switchgear used to clear the fault, and to mitigate disturbance to unfaulted parts of the system. A basic scheme involves a super-resistor which is a superconductor being driven to high resistance when fault current flows either ...

Autonomous switch fault current limiter

2011 North American Power Symposium, 2011
In this paper, the operation of the autonomous switch fault current limiter has been explained and its advantages over previously developed methods have been presented. The tests of current limitation and overvoltage testing, showing the operation of the autonomous switch fault current limiter, have been displayed.

Non‐superconducting fault current limiters

European Transactions on Electrical Power, 2008
AbstractThis paper proposes the use of non‐superconducting DC reactor type fault current limiter (NSFCL) instead of superconducting fault current limiters (SFCLs) which has high cost and technology. Proposed FCL consists of three similar sets, each including a diode bridge and a single non‐superconducting DC reactor.

Superconducting fault current limiter development

IEEE Transactions on Magnetics, 1991
The authors have developed and tested a 400-V 100-A-class fault current limiter wound with AC superconducting wire with ultrafine NbTi filaments. The limiter consists of noninductively wound superconducting trigger coils and a superconducting limiting coil which acts as a reactor.

A superconducting fault-current limiter

Journal of Applied Physics, 1978
A conceptual design is presented for a fault-current limiter for the electrical power utilities which utilizes a superconducting element to commutate the fault current into a shunt resistor. The technical feasibility of the concept is supported by a computer simulation of the switching.
