Abstract

The weather parameters along the overhead line change significantly and this have a significant effect on the thermal behaviour of the conductors. The thermal behaviour of the conductors is of great importance to the optimization and increase in line ampacity. Calculation of line ampacity of transmission lines helps power system operators to solve specific high demand and emergency situations in the power system network and simultaneously ensuring that the temperature limits and line ampacity of the conductors are not exceeded. In this paper, the line ampacity of an overhead line under different weather conditions is analysed. The results from the case study show that changes of weather conditions along the overhead line have an important impact on the line ampacity.
