Impact of dynamic line rating on operational planning calculations of interconnected transmission systems

The ampacity of a conductor presents the maximum constant current that can be carried
through the line without violating safety codes, damaging transmission system components and
jeopardizing of transmission network reliability. Dynamic Line Rating (DLR) is a technology used to
increase the ampacity of electric overhead transmission lines, taking into consideration real
operational conditions. Traditionally, ampacity of transmission lines are seasonally estimated
assuming unfavorable weather conditions.
