This paper focuses on symmetrical component analysis applied to fault detection in power systems with a three-phase reactor-type superconducting fault current limiter (SFCL). Symmetrical component analysis is a fundamental method for analyzing asymmetric faults in power systems, especially in three-phase systems. The study analyzes the behavior of SFCL in limiting fault currents and its effect on the symmetrical components of voltage, current, and impedance during faults. Although SFCL is effective in limiting fault currents, it interferes with the operation of conventional overcurrent relays in fault detection due to the reduced fault current levels. This paper discusses these challenges and highlights the need for improving existing symmetrical component analysis methods to better accommodate the unique characteristics of superconducting devices. In the context of future power system protection, the study suggests that more accurate fault analysis and protection methods, which consider the behavior of superconducting devices, are essential for enhancing system stability and reliability. Furthermore, this study conducts symmetrical component analysis of impedance and superconducting devices, contributing to a deeper understanding of fault characteristics and improving the accuracy of fault detection and system protection.
