Magnetic shielding superconducting fault current limiters (MS-SFCLs) are considered as a new utility device. It is connected in series with the line circuit to limit short circuit currents. Various models of inductive MS-SFCL have been presented for fault current limitation. In this manuscript, a new model of three-phase MS-SFCL is proposed taking into account a better dynamic performance, magnetic shielding, volume, weight and manufacturing cost. The model structure is based on a magnetic core wound by only three primary coils, using an open/close core configuration. The application of MS-SFCL in electric power system depends on the transition from the shielding state to quenching state. The MS-SFCL has low impedance in normal operation of the power grid and has instantaneous large impedance in case of fault. The effectiveness of proposed MS-SFCL is simulated numerically by finite element modeling (FEM) in QuickField simulation software. |
