Modelling and Simulation of Resistive Superconducting Fault Current Limiter (RSFCL) in Three Phase Transmission and Wind Energy Generation System (WEGS) Applications

Abstract: In present scenario, electrical networks are desperately integrating with Superconducting Fault Current Limiters (SFCL) because of their capability to improve the stability, fault compensation within milliseconds, auto- transformation from Superconducting state to normal state. Hence, the characterization and performance of RSFCL integration with the power systems should be analyzed for better utilization for Indian scenario. This paper alights, developed simulation model of RSFCL with Coated Conductors (CC’s) in MATLAB/SIMULINK. This model is simulated to predict the fault compensation capacity during three phase faults in Three Phase Transmission and isolated WEGS respectively. Based on E-J power law the current density and resistance characteristics of RSFCL are analyzed during fault. Different faults such as LG, LLG, and LLLG are investigated, and it is found that RSFCL is very effective in fault compensation with in very first peak and in fewer times in both Three Phase Transmission and isolated WEGS.
