| Popis: | © 2019 IEEE. The superconducting fault-current limiter (SFCL) has been effective in coping with large fault currents and is expected to be largely applicated in the power system to solve the problem of increasing fault-current level in power grid nowadays. However, the coordination between SFCLs and traditional power system devices such as protective relaying has not been researched enough. This paper studies the influences of the resistive-type SFCL on the incremental power frequency relay of the transmission lines. The resistive SFCL is simulated by using thermal-electric analog method. A model of a 220-kV transmission system with the incremental power frequency relay element was built and simulated with the SIMULINK MATLAB software. Three compensation methods to eliminate the negative effects of the integration of SFCL are proposed and compared. Finally, numerical simulation tests have demonstrated the correctness and validity of theoretical analyses. |
