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.

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.

Current limiting level-time characteristic of a superconducting fault current limiter

Cryogenics, 1995
Abstract A model superconducting fault current limiter (SE-FCL) has been developed. The adopted superconducting cable is composed of six strands insulated from each other. The current limiting level of the SC-FCL is measured under two types of overcurrent, a sinusoidal and an inrush current.

Realization study of superconducting fault current limiter

2011 1st International Conference on Electric Power Equipment - Switching Technology, 2011
The fault current for large-scale power systems is higher than normal and interception using a current breaker can thus be difficult. To address this problem, power system reorganization and circuit breaker upgrades can be considered. However, existing systems could be operated by introducing a superconducting fault current limiter.

Basic concepts of superconducting fault current limiter

2016 IEEE 1st International Conference on Power Electronics, Intelligent Control and Energy Systems (ICPEICES), 2016
The need for power demand has been ever increasing due to numerous day-to-day causes. With increase in power demand, the fault levels witness a general rise. The superconducting fault current limiters have been seen as a much needed power device to limit the fault current in the electrical power system.

Application of Superconducting Films to Fault Current Limiter

Japanese Journal of Applied Physics, 1994
The applicability of high-T c-superconducting films to a fault current limiter (FCL) without liquid nitrogen ( L-N2) was investigated. The FCL element consists of a 200-nm-thick YBa2Cu3O7- X (YBCO) film having a current-limiting area 4 mm wide and 90 mm long.
