Recently, a major part of the newly installed wind turbines are of the variable-speed type using permanent-magnet synchronous generators (PMSGs), which are required to meet grid interconnection codes for fault ride-through (FRT), so as to actively contribute to system stability during a wide range of network fault scenarios. This paper suggests a resistive type superconducting fault current limiter (SFCL) to enhance the FRT capability of a PMSG-based wind turbine. The SFCL's mathematical model

Furthermore, the detailed model of a typical PMSG-based wind turbine with the SFCL is built in MATLAB/SIMULINK, and transient simulations are done to assess the SFCL's performance behaviours. From the demonstrated results, the SFCL can availably limit the fault current and maintain a stable DC-link voltage. And also, the SFCL is able to smooth the power fluctuation and strengthen the wind power system's transient performance.
