Sažetak
The continuous increase in electrical power demand entails the need for larger ratings of overhead lines. This is achieved by the construction of new distribution and transmission lines or by increasing the rating of existing lines. For spatial, economic and ecological reasons, contemporary solutions are focused on incrementing the ratings of existing lines. One of these solutions is the real-time determination of line ampacity according to the measured or predicted weather and/or line parameters. The paper is focused on a novel calculation procedure and analysis of the line ampacity weather sensitivity coefficients (WSCs). The calculation of WSCs is based on the sensitivity analysis of the methodology for line ampacity given in Cigre N° 601 Technical Brochure. On the one hand these WSCs allow a fast estimate of the potential in the introduction of real-time ampacity calculation concept. On the other hand they give a good basis on the requirements for the measurement equipment installed in contemporary dynamical line rating systems (DLRSs). Finally, the WSCs are calculated and analyzed for typical aluminum steel-reinforced conductors (ACSRs) present in the Croatian transmission system. Moreover, the analysis of WSCs is done according to the typical design parameters of overhead lines.
