The Economic Analysis of Large Cross-Section Conductor in UHVDC Project

Abstract

Conductor scheme is one of key issues in the design of the UHVDC transmission project, and it is significant for the construction cost and safe operation of transmission line. It can be concluded from analysis on application of existing conductor that the appropriate decrease in number of bundle conductor and increase of the conductor cross-section will reduce line loss, which has remarkable social-economic benefits. In this paper, the economic analysis of large cross-section conductor is conducted based on UHVDC Project. Some useful suggestions are given.
