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.

Development of Superconducting Fault Current Limiters

2006 International Conference on Power System Technology, 2006
Somewhere in a power utility system, a mishap may cause a short- circuit. The sudden reduction in the power grid's impedance will lead to a surge of current, termed fault current. Sometimes, fault currents can create disasters to power generators, distributors, and consumers.

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).

Towards the superconducting fault current limiter

IEEE Transactions on Power Delivery, 1991
The advent of low-loss AC superconductor wires opens the way to a new current limiting technique: that of extremely fast transition from a superconducting state to a resistive state when the fault current exceeds the conductor's critical current. A 25 kV single-phase prototype is described which consists of a Nb Ti superconducting coil without iron ...

A Study on the Effect of Superconducting Fault Current Limiter in Power System with Separated Bus and Superconducting Fault Current Limiter

Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, 2012
Currently, separated buses were increased to limit a fault currents in power transmission system. However, separated buses caused bad influences such as a decrease of reliability and stability. Superconducting fault current limiter (SFCL) was proposed to limit a fault current lately and that has many merits beside any other solutions.

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 ...

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.

Cognition on the current-limiting effect of saturated-core superconducting fault current limiter

2015 IEEE Magnetics Conference (INTERMAG), 2015
The saturated-core superconducting fault current limiter (SCSFCL) is an important facility for limiting the short-circuit fault current of the power grid. However, the cognition or the judgment on the current-limiting effect, which is the key indicator of the SCSFCL, is not unique.

Summary of Superconducting Fault Current Limiter Technology

2012
In recent years, superconducting fault current limiter (SFCL) has become one of the forefront topics of current-limiting technology in the world. In this paper, the structure and working principle of several SFCLs which perform high in the actual power grid, such as resistance type, reaction type, hybrid type, magnetic shielding type, saturated iron ...

The current status of superconducting fault current limiter development

Cryogenics, 1994
Abstract Demand for electric power in Japan has been steadily increasing in recent years.To meet this demand, power networks have been more robustly connected with a view to improving their reliability. However, this has been accompanied by a trend toward a greater incidence of fault currents in these power networks.
