This paper describes the study to analyse the effect of the superconducting fault current limiter (SFCL) on an electric power grid with the wind-turbine generation, which is a representative renewable energy source. Its connection to a power system might more easily increase the short-circuit current during a fault toward its maximum utilization level, which is closer to the rating of circuit breaker, when compared to the case without the wind-turbine system. This can aggravate the reliability of the overall power system. The SFCL can provide the quick system protection during a severe fault. The performance of dynamic damping improvement by the SFCL is evaluated in the existence of the wind-turbine generation system. Therefore, its effectiveness as a protective device for the wind-turbine system is verified with the several case studies by time-domain simulation based on the power systems computer aided design/electromagnetic transients including DC (PSCAD/EMTDC) software.
