Abstract With the growing requirements for the electricity, the security of grid and the environmental protection, the traditional transmission system can hardly meet the needs of urban power supply. The high temperature superconducting (HTS) cable has a possibility to solve these problems, because it can be applied to the extremely small areas or the places where the overhead lines fail to be built due to the security and environmental concerns. In this paper, a simulation model of 110kV/3kA cold dielectric HTS cable is built in PSCAD/EMTDC based on the critical characteristics of the HTS cable, where the quench effects are calculated by Matlab. An external short-circuit fault is simulated in a 110kV HTS transmission line. And then the power flow distributions with and without HTS cable are compared. The results show that the HTS cable has greater short-circuit capacity, and is beneficial to the power grid voltage stability and regulation.

Key words： High temperature superconducting cable three-terminal meshed network power flow distribution short-circuit fault PSCAD/EMTDC
