对饱和铁芯超导限流器(SISFCL)进行了功率损耗分析。利用有限元软件COMSOL中实现的H公式模型，对高温超导(HTS)线圈进行了SISFCL的建模和功耗计算。该模型基于实际的三相35KV/90MVA SISFCL。为了找出高温超导线圈功率损耗的原因，研究了高温超导线圈关键部件的交流磁场。计算并比较了直流偏置电流增大时高温超导线圈的瞬时功耗。分析证明，在实际运行中应考虑高温超导线圈的功率损耗。
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.
