Use of HVDC circuit breaker in HVDC system shown successful results. But imposing DC fault current during DC fault have not achieved yet. To overcome this problem, there is one alternative solution to use of superconducting fault current limiter (SFCL). This paper deals with application of resistive SFCL (R SFCL ) for high voltage direct current (HVDC)

Superconducting fault current limiter (SFCL) in the medium and high voltage grid
2006 IEEE Power Engineering Society General Meeting, 2006Superconducting fault current limiters (SFCLs) combine features not provided by conventional switching devices. In the medium voltage (MV) grid the installation of SFCLs as bus coupler and in the transformer feeders are of special interest. Thus the short circuit power can be increased without exceeding the admissible short circuit strength.

Concentrated power demand can cause a fault current problem in a real power system. The Superconducting Fault Current Limiter (SFCL) application is one of the solutions for this problem. At present, many projects for the development of SFCLs are being done actively throughout the world. In Korea, LS Industrial Systems Co., Ltd.

Proposal of rectifier type superconducting fault current limiter with non-inductive reactor (SFCL)
Cryogenics, 2004A rectifier type superconducting fault current limiter (SFCL) with non-inductive reactor has been proposed. The concept behind this SFCL is the appearance of high impedance during non-superconducting state of the coil. In a hybrid bridge circuit, two superconducting coils connected in anti-parallel: a trigger coil and a limiting coil.

As the size of a power system continues to expand, generation capacity and transmission network expansion may be restricted by the fault current limit. Superconducting fault current limiters (SFCLs) are one of the promising fault current limiting technologies that could have potential for greater use in power systems.

Power flow patterns and fault current levels are influenced by the introduction of distributed generations (DGs) in an electric power system. In particular, the change in the fault current levels caused by DG installation may require a change in the coordination of relays to prevent their misoperation. When DGs are installed in an electric power system,

This paper presents the application of Superconducting fault current limiters (SFCL) for smart grids in order to reduce possible effect of abnormal fault current. Increased demand results in increased generation capacity in power systems which has lead to increased fault current.

Abstract In our first attempt to design a single phase R-SFCL in India, we have chosen the typical rating of a medium voltage level (3.3 kVrms, 200 Arms, 1Φ) R-SFCL. The step-by-step design procedure for the R-SFCL involves conductor selection, time dependent electro-thermal simulations and recovery time optimization after fault removal.
