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

In this study, we examined the long-term plans of expansion for the concept ual design of HTS power cable in the Seoul area. In Korea recently, the des ire for underground power cable on the rise in light of the increasing dema nd for electric power and the environmental restrictions in the urban area. Since the HTS power cable has high power transmission density and low loss characteristics, compared to conventional power cables, we have assumed it s' application between the downtown area and the outskirts of the city, whe re there is large transmission of power. This paper will demonstrate the ef fects of applying HTS power cables in Seoul based on the power system analy sis.
