Line-rating system boosts economical energy transfer

摘要

The authors describe how the Korea Electric Power Corporation (KEPCO) has successfully completed twenty-four overhead transmission line upgrade projects in Korea from 1994 to 1997 for a total cost of US$54.6 million. Upgrades to existing transmission lines were accomplished by replacing existing conductors with high ampacity conductors using existing towers and rights-of-way. Transmission line capacity is doubled with these high-capacity conductors. Planning studies and construction of the upgrade projects were facilitated by using LINEAMPS transmission line ampacity software.
