Feasibility Study of the application of HVDC System to Domestic Power System ' Design of the HVDC system for Sinokchun-Sedaegu 345kV Transmission line

직류변환 송전방식 국내도입 타당성 검토 : 신옥천-서대구 345kV송전선로 1회선 직류변환 설계

This paper describes the feasibility study of HVDC system application to KEPCO power system for increasing power transfer capability or the flexibility of power delivery from one area to the other using the existing transmission line. This paper assumes the 345kV transmission line connecting between Shinokchun and Sedaegu to be converted to the DC line by replacing the AC insulator with that of DC. Then, the HVDC bipole system of 1000MVA with $\pm300kV$ is designed and the contingency studies are carried out.
