“…4 illustrates the output 3-phase current of PMSG before and after applying SFCL. Before applying SFCL, the current increased instantaneously on all phases with different values depending on the instant of fault for each phase [22]. The maximum fault current occurred on phase b with instantaneous value of 282 A, which represents 220% of the nominal peak current.…”

Integrating permanent magnet synchronous generator (PMSG) wind turbines with DC microgrids have attracted a great attention due to the inherent merits of DC systems. However, under fault conditions, the excessive energy during fault will be reflected on PMSG rotating parts causing over-speed, mechanical stresses and fast aging. Also, large fault currents will force generator-side converter to disconnect making it not complied with grid codes. Accordingly, this paper aims to apply superconducting fault current limiter (SFCL) to enhance the performance of PMSG wind turbines with DC microgrids under fault conditions. PSCAD/EMTDC software is used to build the system under study that includes PMSG, controlled AC/DC converter, SFCL and DC bus. The behavior of SFCL in enhancing the DC output of the converter is first studied. Then, the impact of using SFCL on the speed, torque, and output current of PMSG is investigated and discussed. Finally, the suitable current limiting resistance is adopted considering DC output as well as PMSG speed.  Index Terms-PMSG wind turbines, DC microgrids, superconducting fault current limiter, current limiting resistance.

“…Regarding the importance of this parameter and looking at the performed studies that have individually concentrated on the impact of fault resistance and fault distance on the FCRR of SFCL in literatures, a few detailed studies can be found. The author in evaluates the impact of the fault resistance on the current limiting behavior of RSFCL, but fault distance impacts have not been considered in this work. In addition, no mathematical expression has been presented to describe the current limiting behavior of RSFCL.…”

Summary Superconducting fault current limiters (SFCLs), as the novel power system devices, have attracted attentions in the last years. However, in order to achieve the maximum benefit from SFCLs, their interaction with power system should be comprehensively evaluated before equipping the power system with them. This paper investigates the effect of fault resistance and fault distance on the steady‐state fault current reduction ratio (FCRR) of hybrid SFCL. Based on the equivalent circuit model, analytical studies are presented to obtain the relation between 2 abovementioned factors and the FCRR of hybrid SFCL. Then, through the detailed simulation studies, the current limiting behavior of hybrid SFCL is evaluated when the value of fault resistance and the position of fault change in wide range. As a result, although the hybrid SFCL is able to reduce the fault current under different circumstances; however, FCRR significantly varies under outside the control changing circumstances. For far faults and faults with high fault resistance, the FCRR of hybrid SFCL is not as good as the other fault conditions. Hence, in the last section of the paper, the remedial actions to enhance the performance of hybrid SFCL during these conditions are proposed.
