| This paper proposes a methodology for determining the transient dynamic ampacity of overhead transmission line (OHTL) conductors, with subsequent application to both conventional aluminum conductor steel-reinforced (ACSR) and high-temperature low-sag aluminum conductor composite core (HTLS ACCC) conductors under the specific conditions of the Slovak transmission system. The foundation of the developed algorithm is the conductor heat balance equation defined in CIGRE Technical Brochure No. 601 (CIGRE 601), which accounts for the physical effects influencing both the heating and cooling of the conductor under real operating conditions. While CIGRE 601 provides a framework for calculating the steady-state maximum ampacity for a given conductor temperature limit, the algorithm introduced in this study further enables the evaluation of short-term overloading capability, including the corresponding duration during which the conductor temperature remains within safe limits. The ability to assess temporary overloading offers valuable operational flexibility, particularly in critical operating conditions. The study demonstrates that the application of dynamic ampacity assessment, especially when combined with the use of HTLS conductors, represents an effective solution for increasing the power transfer capability of existing OHTLs from both a time and economic perspective—without the need to construct new line corridors or modify existing tower structures. |
