Critical Current, Critical Temperature and Magnetic Field Based EMTDC Model Component for HTS Power Cable

Abstract

Before applying the High Temperature Superconducting (HTS) power cable to real utility network, system analysis should be performed using simulation tools. For the practical use of HTS devices in electrical power system, prior simulation analysis is very important. PSCAD/EMTDC simulation is one of the most popular and useful analysis tools for electrical power system. Unfortunately the model component for HTS power cable is not provided in the PSCAD/EMTDC simulation tool. In this paper, EMTDC model component for HTS power cable has been developed considering critical current, critical temperature, magnetic field, and recovery time constant which depend on the sorts of HTS wire. The numerical model of HTS power cable in the PSCAD/EMTDC was designed by using the real experimental data obtained from a real HTS 1G wire test. The utility application analysis of HTS power cable was also performed using the model component developed. The component for HTS power cable could be variously used when the power system includes HTS power cable, especially it will be readily analyzed by the PSCAD/EMTDC in order to obtain the data for the level of fault current, power flow, and power losses, and so on.Index Terms-Critical current, critical temperature, HTS power cable, magnetic field, PSCAD/EMTDC.

RTDS-based Model Component Development of a Tri-axial HTS Power Cable and Transient Characteristic Analysis

“…The developed model component was applied to a 22.9 kV class power system model, which consisted of a 5 km distribution line made of ACSR (aluminum conductor steel reinforced) 160 and a 50 MVA load [3]. The impedance of the distribution line was 0.506 + j0.0025 Ω.…”

“…Before using the tri-axial HTS power cable in a commercial installation, the system should be analyzed using simulation tools in order to confirm both the characteristics and the effects of the cable. The transient characteristics of the triaxial HTS power cable are different from those of other HTS power cables as well as conventional copper power cables depending on the structure and whether the cable is under a steady or transient state due to the quench [3].…”

Fault Current Limitation Coordination in Power Transmission System With Superconducting Fault Current Limiting Cables (SFCLC)

“…Although the high capacity of power system induces a large fault current, superconducting fault current limiters can enhance the system stability by protecting electric power apparatus and systems from a large fault current. In recent years, several research and development was carried about superconducting power apparatus with such a fault current limiting function [1]- [6]. Then, we have proposed a Superconducting Fault Current Limiting Cable, abbreviated to "SFCLC" [7].…”

Analysis of high temperature superconducting cable model under fault current

“…The superconducting power technology has been applied in the nuclear fusion field in recent years [1,2]. HTS cable gradually attracts technical people's attention by its high transmission capacity, small size, low loss, low electromagnetic radiation and little environmental pollution [3,4].…”
