The resistive type high temperature superconducting fault current limiter (HTSFCL) limits the fault current with the resistance that generated by fault current.
Besides, we introduce the working principle of the saturated iron core superconductive fault current limiter and its current-limiting effects in the electric power transmission line.
High-temperature superconductivity projects for low AC loss conductors, a 70 kA current lead and a fault current limiter are currently in progress.
When the fault occurred in the power system, the superconducting fault current limiter (SFCL) rapidly limited the fault current to protect the power devices with preventing power failure.
The other is to increase the installations of electrical equipment or upgrade them, such as installing the current limiting reactor or fault current limiter (FCL), even replacing with the high-impedance transformer.
In [83], a non-adaptive relaying scheme is discussed, which utilised the fault current limiter (FCL) to locally limit the DER fault current during fault conditions and thus restores the original coordination among the relays.
Therefore, installing the fault current limiter is similar to installing the current limiting reactor.
An inductive superconducting fault current limiter protects power system by limiting the amplitude of fault current by the inductance of its dc reactor.
Although, a superconducting fault current limiter (SFCL) guarantees the fast limiting operation, it usually needs a considerably long time to recover to superconducting state after the quench.
However, disconnecting DGs, limiting penetration level, using Fault Current Limiter (FCL) and executing communication-based adaptive approaches are not such affordable solutions.
We investigated the current limiting characteristics of the flux-lock type superconducting fault current limiter (SFCL) with series or parallel connection of two coils.
