On functioning of Siberian IDGC branch of PJSC Rosseti – JSC Chitaenergosbyt

Abstract

Specifics of the functioning of the electric grid company over the period of its activity in 2016 – 2022 are considered. Based on the publicly available data, an analysis of the structural features of the company, as well as the electric energy balance for its transmission to and from the company's networks, taking into account losses arising during the electricity transportation to consumers, was carried out. The characteristics of generating capacity, as well as the number of substations on the Trans-Baikal Territory and in the Republic of Buryatia are presented, their age assessment is given. The level of electricity consumption is analyzed, as well as the structural composition of consumers receiving electric energy through the company's networks. Based on available information about emergency situations, the number of failures that occurred in the company's networks during the period under study, as well as the causes of those failures, were analyzed. It has been established that the greatest number of failures is associated with the wear of electrical grid equipment, which causes a collision of wires of overhead power lines, their breakage, as well as the breakdown of high-voltage insulators. The percentage ratio of the main causes of failures in the company's electrical networks has been determined. Based on the use of Matlab graphic editor technologies, the visualization of the analyzed dependencies was carried out, which enabled to have a demonstration of changes in the number of failures, the amount of under-supplied electrical energy, as well as economic damage from this under-supply. Graphical diagrams are presented and a detailed analysis of the causes of emergency events for the current half of 2022 is given. Reversible malfunctions (unstable failures) are noted, and their share in the total volume of emergency situations is determined. Recommendations have been developed for the company specialists to improve the reliability of power supply. The results obtained can be useful both to the management and specialists of the company in question, as well as to scientific and technical workers and engineering personnel engaged in research in the field of improving the reliability and safety of functioning of electric power systems.
