“…Various models of HTSs cable have been proposed recently. In [23], modelling of an HTS power cable in power system computer-aided design/electromagnetic transients including direct current (PSCAD/EMTDC) was presented. This HTS cable model was developed based on cable models from the master library.…”

Bypassing transient current through copper (Cu) stabilizer layers reduces heat generation and temperature rise of high-temperature superconducting (HTS) conductors, which could protect HTS cables from burning out during transient conditions. The Cu layer connected in parallel with HTS tape layers impacts current distribution among layers and variations of phase resistance in either steady-state or transient conditions. Modeling the multilayer HTS power cable is important for transient studies. However, existing models of HTS power cables have only proposed HTS cables without the use of a Cu-former layer. To overcome this problem, the authors proposed a multilayer HTS power cable model that used a Cu-former layer in each phase for transient study. It was observed that resistance of the HTS conductor increased significantly in the transient state due to a quenching phenomenon, which made the transient current mainly flow into the Cu-former layers. Since resistance of the Cu-former layer has a significant impact on the transient current, detailed modeling of the Cu-former layer is described in this study. The feasibility of the developed HTS cable model is evaluated in the PSCAD/EMTDC program.

“…An accurate model is especially important for working condition prediction which is helpful for the power flow control, relay protection and overvoltage protection. Several models have been proposed based on PSCAD/EMTDC to investigate the current distribution in the conductor layer under normal and faulty conditions [4], [5]. However, the special bonding structure was not considered in the HTS cable model.…”

Nowadays, the power demand has been dramatically rising in highly populated load areas. The high-temperature superconductor (HTS) cables are one possible solution for the electricity transmission due to their high transmission capacity and tremendously lower electrical loss compared with traditional power cables. A comprehensive and accurate model is very important to predict the working condition prediction for the purpose of power flow control, relay protection and overvoltage protection, especially for HTS cable which is highly expensive and lacking of operation experience. In this paper, a simplified analytical model of HTS cable is presented to further facilitate operating condition simulations. The inductances are derived and the result is verified with FEM software COMSOL. The self-, mutual inductances, capacitances between each layer are calculated to build the parameter matrixes. By appropriate transformation, electrical parameter matrixes can be converted into simplified PI sections. A simple simulation model for power system containing HTS cable can be built up by using EMTP-ATP program. The instructive guide for protection systems for HTS cables may be provided according to the simulation results. The simplified distributed parameters model described in the paper is also helpful for structure optimization to obtain uniform current distribution in superconductor layers.Index Terms-Electrical parameters, high-temperature superconductor (HTS) cables, simplified model. 1051-8223
