In this paper, the authors present a comparative study of inductive and resistive superconducting residual current limiters (SFCLs) from the perspective of current limiting and transient stability of the power supply system. Different types of SFCL can be used to reduce the magnitude of the fault current in a power system. The two most commonly used types are the resistive type (rSFCL) and the inductive type (iSFCL). The study aims here to analyze the performance of SFCL using various switching algorithms when a fault occurs in a simple high voltage (HV) network.

Due to its many advantages such as the improved power quality, high energy efficiency and controllability, etc. the variable speed wind turbine using a doubly fed induction generator (DFIG) is becoming a popular concept and thus the modeling of the DFIG based wind turbine and improvement in the transient fault conditions is an important consideration. In this paper, Transient stability improvement has been done by using Superfluous Fault Current Limiter [SFCL]. A new design of SFCL IGBT- Bridge-type SFCL shunted with a variable resistor Rsh has been proposed. Rsh is modeled to decrease the terminal voltage deviation to minimum level by reducing the amount of current at the bus terminal. Comparison of Voltage deviation and current deviation with the resistive type SFCL and IGBT- bridge-type SFCL show considerable decrease in both quantities by using IGBT- bridge-type SFCL. The values of voltage deviation at the bus terminal is 8.223 e-8 % for proposed SFCL which is less than the resistive type SFCL that is, 14.4 e-8 %.  The huge voltage sag has been considerably reduced by reduction of high level of current to 0.0004401 % in IGBT-bridge-Type SFCL from 0.0004624% in resistive type SFCL. Thus proposed SFCL has caused significant improvement in transient stability keeping the deviation in active and reactive power during faults to minimum level.
