An Optimal Design Approach for Resistive and Inductive Superconducting Fault Current Limiters via MCDM Techniques

The design process of a superconducting current limiter (SFCL) requires simulation and definition of its electrical, magnetic and thermal properties in form of equivalent circuits and mathematical models. However, any change in SFCL parameters: dimension, resistance, and operating temperature can affect the limiting mode, quench time, and restore time. In this paper, following the simulation of...

Study of Superconducting Fault Current Limiter Device in a AC Railway System

Development of the electric networks led to more interconnection in this system, therefore high level of short circuit faults flows in the networks. Many destructive damages such as instability, insulation problems and voltage mitigation can highly play unwanted influences on the system’s equipment. Using appropriate protection devices like high voltage fuses, fast switches, and such devices...

The Impact of Superconducting Fault Current Limiter Locations on Voltage Sag in Power Distribution System

In this paper, the impacts of installing superconducting fault current limiter (SFCL)in radial and loop power distribution system are evaluated to improve voltage sag in both cases of with and without distributed generations (DG). Among various SFCLs, the hybrid type with a superconducting element in parallel with a current limiting reactor (CLR) is selected. This is more effective than resisto...
