ABSTRACT
Studies aimed at the economically sound increase in the capacity of existing power lines and improvements in their design are relevant today. In addition to the well-known design methods of influencing the capacity of the transmission line, there are other meanings that can affect its natural capacity, which is directly related to the capacity. Therefore, the purpose of this study was to find possible methods of increasing natural power and evaluate their effectiveness in real configurations. The basis of the methodological approach applied in this study is a qualitative combination of methods of systematic analysis of ways to increase the capacity of power lines with the analytical investigation of the prospects for its impact on wave resistance to increase the natural power of the line. The conducted research determined the total influence of the analyzed factors on the increase in transmission capacity and identified the most optimal configuration from a technical and economic standpoint. Based on the results of the calculation of the natural capacity of the configurations, conclusions were made about the significance of the impact of each of the above factors, and the economic effect of their implementation in the integrated power system was established. Improvement of this methodology can, in the long run, serve as a tool for calculating configurations for economic and technical relevance, or serve as a foundation for further identification of factors affecting the transmission capacity of power lines.

Badania mające na celu ekonomicznie uzasadnione zwiększenie przepustowości istniejących linii elektroenergetycznych i ulepszenia w ich projektowaniu są obecnie aktualne. Oprócz dobrze znanych metod projektowania wpływających na przepustowość linii przesyłowej, istnieją inne znaczenia, które mogą wpływać na jej moc naturalną, która jest bezpośrednio związana z przepustowością. Dlatego celem niniejszego badania było znalezienie możliwych metod zwiększenia mocy naturalnej i ocena ich skuteczności w rzeczywistych konfiguracjach. Analizowane czynniki obejmują: zastosowanie przewodów o ulepszonych parametrach, wpływ liczby komponentów w fazie, odstęp fazowy, obecność warstwy izolacyjnej na przewodach. Podstawą podejścia metodologicznego w tym badaniu jest jakościowe połączenie metod systematycznej analizy sposobów zwiększenia przepustowości linii elektroenergetycznych z analitycznym badaniem perspektyw ich wpływu na opór falowy w celu zwiększenia mocy naturalnej linii. Przeprowadzone badania pozwoliły określić łączny wpływ analizowanych czynników na zwiększenie zdolności przesyłowych oraz wyznaczyć najbardziej optymalną konfigurację z technicznego i ekonomicznego punktu widzenia. Na podstawie wyników obliczeń mocy naturalnej konfiguracji, sformułowano wnioski dotyczące istotności wpływu każdego z powyższych czynników oraz określono efekt ekonomiczny ich implementacji w zintegrowanym systemie elektroenergetycznym. Udoskonalenie tej metodyki, w dalszej perspektywie, może posłużyć jako narzędzie do obliczania konfiguracji pod kątem przydatności ekonomicznej i technicznej lub stanowić podstawę do dalszej identyfikacji czynników wpływających na zdolności przesyłowe linii elektroenergetycznych.
