Abstract
This paper presents a novel scheme for reducing an asymmetry current with SFCL (Superconducting Fault Current Limiter) operation during transient period, when a fault occurs in power systems. The main idea is installation an auxiliary SFCL with characteristics, which reduces the asymmetry fault current in first half cycle before the operating of main SFCL. For proper activities of SFCLs, the principle of asymmetry current nature is reviewed. A scheme of asymmetry components reduction with SFCL is then explained. The EMTP/ATPDraw model of SFCLs using MODELS language developed and simulated to verify the performance and effectiveness.
