Abstract

For the design to prevent the saturation of iron core and the effective fault current limitation, the analysis for the operation of the flux-lock type superconducting fault current limiter (SFCL) with consideration for the hysteresis characteristics of iron core is required. In this paper, the hysteresis characteristics of flux-lock reactor, which is an essential component of flux-lock type SFCL, was investigated. The hysteresis loss of iron core in flux-lock type SFCL does not happen due to its winding's structure especially in the normal state. From the equivalent circuit for the flux-lock type SFCL and the fault current limiting experiments, the hysteresis curves could be drawn. Through the analysis for both the hysteresis curves and the fault current limiting characteristics due to the number of turns for the 1st and 2nd winding, the increase of the number of turns in the 2nd winding of the flux-lock type SFCL had a role to prevent the iron core from saturation.
