“…In addition, FEMs are not implementable for real-time modelling and applications, and are often used in the design stage of a superconducting device. (iii) The third method of characterizing the fault performance of HTS cables is the equivalent circuit model (ECM) [15][16][17][18][19][20][21][22][23][24]. ECMs are faster than FEMs and offer high accuracy.…”

High Temperature Superconducting (HTS) cables are promising devices for electrical power transmission of renewable energy resources, where their fault performance study is vital to avoid interruptions in electric system. In this study, fast intelligent surrogate models were presented to estimate the fault performance of a 22.9 kV/50 MW HTS cable to make the fast fault performance analysis of the HTS cables possible, during the design stages. Different fault scenarios were considered under different fault durations, fault resistances, and types of faults. Then, fault energy, fault current, fault type, fault duration, and fault resistances were fed into surrogate model, as inputs. On the other hand, the outputs were temperature of ReBCO tapes, former temperature, ReBCO layer current, and total resistance of each phase. For surrogate modelling, Cascade Forward Neural Networks (CFNN) was used. Results show that the accuracy of CFNN-based model to estimate fault performance of the cable with an average accuracy of 99.1%. Finally, the impact of considering fault energy, fault current, and both, as the inputs of the models, on the final accuracy was explored. Results showed that fault energy consideration could increase the accuracy of surrogate model.

“…In [6,7] dynamic model of HTS cable was developed and implemented with the dynamic simulation software and with purpose of stability analysis of power grids with integration of HTS cable. Steady-state electrical model of HTS cable was developed in [8][9] primarily to analyze the response of HTS power transmission cables under fault condition.…”

Physical and electrical characteristics of hightemperature superconducting (HTS) DC power cables have been modelled to assess their benefits compared to conventional XLPE cables for use in distribution networks of tightly coupled electrical systems such as the Navy all-electric ship. The characteristics of a 30-m long HTS DC cable prototype that was successfully demonstrated recently were used to evaluate the benefits of increased power density, both volumetric and gravimetric, in comparison with similarly rated XLPE cables. The response of HTS cables for electrical faults and switching harmonics were studied through electrical models. The results of transient characteristics of HTS cables were compared to that of normal cables under identical network conditions. The peak voltage observed for the HTS cable network when faulted was considerably smaller than that of the XLPE bundle under a 1 kΩ ground resistance. On the contrary, the over voltage of the ungrounded HTS cable system was larger than that of the XLPE cable. The damping constant of the HTS cable was 3 times higher than XLPE cable.
