A study on the application effects of HTS power cable in Seoul

In this study, the authors examined the long-term plans of expansion for the conceptual design of HTSC power cables in the Seoul area. In Korea recently, the desire for underground power cables on the rise in light of the increasing demand for electric power and the environmental restrictions in the urban area. Since the HTSC power cable has high power transmission density and low loss characteristics, compared to conventional power cables, they have assumed its application between the downtown area and the outskirts of the city, where there is large transmission of power. This paper demonstrates the effects of applying HTSC power cables in Seoul based on the power system analysis.
