- Abstract
The purpose of the scientific article is to study the transport of electric energy through the electric networks of one of the branches of PJSC ROSSETI of the South – Rostovenergo. The article analyzes the current state of electrical networks, provides balance characteristics for the transmission of electrical energy to and from the company’s networks, as well as the level of transport losses in these electric networks. In accordance with the tasks set, an analysis of emergency shutdowns in the studied networks for the period 2018–2024, as well as the amount of undelivered electric energy and the corresponding economic damage as a result of failures in these networks was carried out. As a result of the analysis, it was found that 42042 emergency shutdowns occurred during the specified interval, as a result of which the undersupply of electricity amounted to 19821.34 thousand kWh, which led to an economic damage of 664986.81 thousand rubles. The most characteristic groups of reasons for these emergency shutdowns have been identified. It was found that the share of only 2 groups accounts for almost 77 % of the total number of refusals for established reasons. Based on the dynamics of emergency situations according to the established three groups of causes, a prognostic assessment of failures in the studied networks for the short term was carried out. Based on the use of MATLAB graphics editor technologies, diagrams have been obtained that visualize the nature of changes in the studied parameters in the company’s electrical networks. Based on the conducted research, recommendations have been formulated for the company’s management to improve the efficiency of power transmission.The results obtained may be of interest to the heads of the relevant services of electric grid companies, as well as researchers engaged in research in the field of improving the reliability of electricity supply
