چکیده :

Although Voltage Source Converters based on HVDC (VSC-HVDC) systems have several advantages, such as renewable energy transmission and long-distance power system connection, they are vulnerable to DC fault currents. Concerning the inherent characteristics of high-temperature superconducting (HTS) material, using HTS in the fault current limiter could be a solution to limit the current in VSC-HVDC. The present paper seeks to provide an elaborately better solution to the problem mentioned above of the fault currents than what has previously been proposed. The object of this paper is a modified flux-coupling-type superconductor fault current limiter (SFCL) to attenuate the DC fault current in VSC-HVDC system. The working principle and operation of the SFCL and VSC-HVDC systems are modeled in detail, involving interplay or synergy between electrical and thermal properties. The simulation results demonstrate that the purposed modified flux-coupling-type SFCL has proper performance in mitigating the DC fault current.
