摘要

研制超导故障限流器的恢复时间具有不确定性。一般来说,即使考虑到SFCL技术的进步,恢复时间估计在1秒以上。但韩国电力系统的断路器自动合闸时间为0.3秒。由于恢复时间超过了保护系统的重合闸时间,在电力系统中不可能只应用一个SFCL。本研究提出了两种新的电力系统SFCL系统。该系统考虑了实际电力系统的自动重合闸保护,由两个并联的sfcl组成

A Study on SFCL Systems for Korean Power System Application
The recovery time of developing SFCL (superconducting fault current limiter) has an uncertainty. In general, the recovery time is estimated at 1 sec and more, even though the progress of SFCL technology is considered. However, auto-reclosing time of circuit breaker is 0.3 sec in Korean power system. It is impossible to apply only one SFCL to power system because the recovery time is over the reclosing time of protection system. This study proposes two new SFCL systems for power system application. The proposed systems consider auto reclosing action for the protection in practical power system and consist of tow parallel SFCLs
