Závislosť prenášaného výkonu a vonkajšej teploty od veľkosti strát vo vybraných prenosových vedeniach

Abstract

This thesis focuses on the analysis of losses in selected transmission lines of the Czech Republic's transmission system, with an emphasis on technical losses influenced by temperature. The introduction of the thesis includes a theoretical analysis of line parameters, network calculations, and an analysis of the energy situation of the Czech Republic’s transmission system. The solution approach utilizes theoretical knowledge and data summarized in the introduction of the work. For the loss calculations, real network parameters measured by the WAMS system and actual temperature measurements from meteorological stations across the Czech Republic are used. The thesis then addresses and solves the issue of losses and the impact of temperature for a specific transmission line under investigation. A solution procedure is established for two specific days, during which a loss analysis is conducted, and an optimal predictive model is determined. The conclusion of the thesis presents the results achieved.
