ASSESSMENT OF ELECTRICITY LOSSES IN OVERHEAD TRANSMISSION LINES IN A REGIONAL ENERGY SYSTEM

The purpose of this article is to conduct a comparative assessment of the impact of key parameters of 35 kV overhead power lines (OPL) on the level of electricity losses. To this end, a comprehensive analysis of the condition of the 35 kV OPL electrical system was carried out, taking into account a combination of operational and climatic factors. Electricity losses are a key indicator of the reliability and technical and economic efficiency of power systems, which necessitates the identification of parameters that determine their reduction. The study is based on the use of correlation and regression analysis applied to the parameters of the power system operating mode using the example of a specific 35 kV power line in the Sughd region. The processes of electricity generation, transmission, and distribution are accompanied by inevitable losses, the level of which determines the efficiency of the lines' operation. As part of the study, the statistical model was tested for multicollinearity using Fisher's criterion. The relevance of the study was established by comparing theoretical propositions with experimental data. The novelty of the work lies in taking into account the influence of climatic conditions on changes in the technical condition of overhead line wires and, as a result, on the amount of electricity losses. A theoretical analysis and statistical processing of data characterizing the operational and climatic factors affecting losses in 35 kV overhead lines were performed.
