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.

Economic Comparison

At present, large section conductors applied in domestic ±800kV ultra-high DC power transmission line consist of 6×720mm2, 6×900mm2 and 6×1000mm2 conductors. This paper analyzes initial engineering investment and mechanical performance of 6×JL1/G2A-720/50, 6×JL1/G3A-900/40, 6×JL1/G3A-1000/45, 6×JL1/G2A-1250/70 and 6×JL1/G2A-1520/125 conductor plans, carry out economic comparison of the whole life period of these 5 conductor plans, demonstrate economic of 6×JL1/G2A-1250/70, and 6×JL1/G2A-1520/125 conductor plans in ±800kV ultra-high DC power transmission line is more advantageous when annual loss hours is too high, and the 6×JL1/G2A-1250/70 plan can save initial investment of engineering compared to the 6×JL1/G2A-1520/125 plan.
