Product description

KEPCO's nationwide multi-loop transmission grid transports electric power with high reliability. Monitoring and controlling systems ensure the safety of underground transmission lines in urban areas and KEPCO applies its extensive experience and technology for maximum operational efficiency. Aging and outdated facilities are constantly replaced or upgraded at appropriate time. In particular, KEPCO accelerates the construction of 765kV large-capacity transmission systems to transport much more electricity with less power loss.

Transmission voltages in Korea are 765kV and 345kV for trunk routes, and 154kV or 66kV for local networks. The 66kV lines are being replaced. KEPCO is now carrying out the second stage of the 765kV power transmission project that will serve as the backbone of the transmission in the 21st century. The power network of Jeju Island is now connected to the mainland transmission system by submarine high-voltage direct current (HVDC) cables. The Supervisory Control and Data Acquisition (SCADA) systems have been used to remotely monitor and control substation operations. In addition to equipment and facility upgrading, more substations are being automated and built indoors to secure power supply reliability.
