Abstract
Since fault current tends to increase with electrical power demand, current-limiting technology for overcurrent have been investigated. As a promising candidate, superconducting fault current limiter (SC-FCL) is expected to be introduced into power system. It is one of the most important performance required for the SC-FCL to recover to a normal operating mode, i. e., superconducting state rapidly after current interruption. In this paper, the recovery time of a SC-FCL introduced into a distribution power system is discussed. To obtain the fundamental data, the recovery time of short Nb-Ti superconducting cables were measured. We developed a calculation method of the recovery time and it was confirmed that the calculated results agree with the measured ones. The recovery characteristics of a SC-FCL in a 6.6kV distribution system for the short-circuit fault near the substation. We considered 3 cycles and 17 cycles as the period from the fault occurrence until the current interruption. As a result, it is suggested that the superconducting cable length required to recover within high speed reclosing time of 0.3 sec are more than 270m and 480m for 3 cycles and 17 cycles respectively.
