SPICE model of high-temperature superconducting tape: application to resistive fault-current limiter

摘要

SPICE is an open source electronic circuit simulator and is often assumed to be an industry standard. In this paper we propose a simple SPICE model for ReBaCuO coated conductors taking into account the main aspects of their electrical and thermal behaviors. The model is focused on the transient analysis of the conductors in resistive-type superconducting fault-current limiters (RSFCL). Close agreement between the model and experimental data has been observed in the fault-current tests of both short samples and the element of the RSFCL prototype. As an additional example, the formation of the overheated domain has been simulated, and results are compared to experimental observations.
