Development of a PSCAD/EMTDC Model Component for AC Loss Characteristic Analysis of HTS Power Cable

摘要

Although Electromagnetic power transient analysis software (PSCAD/EMTDC) is one of the useful simulation tools, it does not provide a High Temperature Superconducting (HTS) power cable component, which has the same impedance characteristic of a real HTS power cable. The authors have already proposed a model component of the HTS power cable under the fault condition and simulated power system including the HTS power cable component. The authors, in this paper, developed a PSCAD/EMTDC model component of the HTS power cable that includes the AC loss characteristic. The AC loss of the superconductor changes due to the magnitude of the transport current. The relational characteristics between the AC transport current and resistance were measured using a model cable. The obtained characteristics were applied to the model component of PSCAD/EMTDC. The developed model component was used in the EMTDC simulation circuit. The simulation results show the same characteristics as the experiment results. The resistance variation of the HTS power cable and AC loss could be simulated using the developed model component and the component will effectively be used for the AC loss related simulations.
