Abstract
This paper presents the power dissipation analysis on saturated iron-core superconducting fault current limiter (SISFCL). The modeling of SISFCL together with its power dissipation computation on a high-temperature superconducting (HTS) coil was executed by the H-formulation model implemented into the finite element method (FEM) software package COMSOL. The model was based on the practical three-phase 35-kV/90-MVA SISFCL. The ac magnetic field in the crucial parts of SISFCL was studied to discover the origin of power loss on the HTS coil. The instantaneous power dissipations in the HTS coil with increasing dc bias current were computed and compared. Analysis proved that power dissipation in the HTS coil of SISFCL should be taken into account for the real operation.
