Abstract
Superconducting fault current limiter (SFCL) is a prospective electric devices connected in series in power grid to limit short-circuit current. A 10.5Â kV/1.5Â kA 3-phase SFCL with HTS coil of 6.24Â mH was developed at IEECAS in China in 2005, which was operated in a local power grid in Hunan province for more than 11,000Â h, and integrated lately in a superconducting power substation in Baiyin city in 2011 and is still running safely and reliably. In order to reduce the fault response time and enhance the performance of the SFCL, we analyzed the structure characteristics of the SFCL and discussed the variation of currents and voltages of the HTS coil and the bridge during the fault time. The simulation and tests results of power system validate the feasibility of the fast fault identification method.
