Abstract:
Short circuit currents show an upward trend in Multi-Terminal High Voltage (MTHV) DC systems. DC resistive type Supercon-ducting Fault Current Limiters (SFCLs) can limit short circuit currents to a much lower level to improve the stability of MTHV DC system. Superconducting tapes used for DC SFCL will quench after a short circuit current attack. Then temperature and voltage of the tapes will increase. The objective of this paper is to obtain the effects of short circuit currents on quench and re-covery properties of the superconducting tapes of DC resistive type SFCLs. YBCO tapes was chosen as investigation samples. This paper concluded that for higher short circuit currents, the temperature and the voltage of the tape was higher. The highest temperature was 379.2 K for YBCO tapes when a short circuit current of 10 kA applied for 50 ms. Recovery time of short circuit current of 10 kA was 240 ms longer than the recovery time of the short circuit current of 500 A. Quenched resistance curves gotten by experiments and analysis were similar, which proved the accu-racy of the analysis. IEEE
