Technology and Design Standards of 765kV 1cct Transmission Line

765kV 1회선 송전선로 기술기준 및 설계방안

To solve the difficulty in obtaining transmission routes and substation sites. increase the transmission capacity between generation sites and load centers. and enhance the stability of the power system. we have constructed and operated the 765kV double circuit transmission line(hereunder T/L) from the Dangjin thermal power plant and the Uljin nuclear power plant to the metropolitan. It makes it possible for us to accumulate know-how of the 765kV system that is the highest operating system level in Asia. As the second 765kV project, we are going to construct the 765kV single circuit T/L between Ansung and Gap yung. Because of the different electrical and mechanical characteristics. we are in need of different design technology. This paper presents the optimal design of 765kV single circuit transmission line after due consideration about the arrangement of conductors. the shape of a tower, insulation, etc.
