Influences of superconducting fault current limiter (SFCL) on superconducting generator in one-machine double-line system [PDF]

IEEE Transactions on Appiled Superconductivity, 2003
Analysis of superconducting generator in single machine double-line infinite-bus transmission system equipped with SFCL's has been performed by use of EMTDC/PSCAD. When some faults occur in one transmission line, the SFCL in the fault line operates and then the peak fault current can be limited to expected value by use of a function of the SFCL ...

Optimal placement of resistive superconducting fault current limiter by considering short‐circuit current and transient stability of power system

IET Generation, Transmission &Distribution, Volume 17, Issue 19, Page 4304-4315, October 2023., 2023
The optimal placement of a resistive‐type superconducting fault current limiter (RSFCL) to achieve good power system transient stability is proposed. Procedure fault analysis is applied to consider the magnitude of the short‐circuit currents and the line located close to the generator for the placement of the device.

Optimal placement and coordination of the protection devices simultaneous with optimal allocation of the DGs

IET Generation, Transmission &Distribution, Volume 17, Issue 18, Page 4119-4133, September 2023., 2023
This paper puts forward a new optimization framework to deal with the optimal coordination of the protection devices and optimal allocation of the DGs and the protection devices simultaneously. To such aim, it is important to reflect the coordination between protection devices in the total objective function.

Analysis on Current Limiting Characteristics of a Superconducting Fault Current Limiter (SFCL) with a Peak Currnt Limiting Function

Journal of the Korean Institute of Electrical and Electronic Material Engineers, 2011
The superconducting fault current limiter (SFCL) with a peak current limiting function according to the initial fault current with the different amplitudes was suggested. The proposed SFCL, which consists of two limiting components, causes only the first superconducting element among two limiting components to be quenched in case that the initial fault
