An Efficient Electric Installation Design and Implementation for Electric Railway Tunnels

The efficiency and performance of electric facilities in electric railway tunnels are quite important factors for operation and maintenance of railway since most of maintenance works for railways are doing during the night. Specially, in the railways like Gyeong-Chun Line passing through many mountains, many parts of railways are constructed with tunnels. So, this paper proposes the efficient electrical installation design scheme for railway tunnel considering the system performance, economics, and the reliability of power supply to tunnel electric facilities. Finally, the proposed design scheme is implemented to the tunnel design for Gyeong-Chun Line (Electric Railway).
