Assessments of electric energy transportation through the electric grid of PAO Rosseti Tsentr

Abstract

The paper aims to analytically assess the reliability of energy transmission through the electric grid of PAO Rosseti Tsentr. The study describes the company’s structure and provides a detailed balance of electric energy transmission through the company’s grid and from the grid to the consumers. The shortcomings of the company’s reporting activities are noted. Based on publicly available information, the authors analysed the accidents that affected the company’s grid within the addressed period of time while noting the specificity of energy transmission in each of the company’s branches. The concept of specific accident rate is introduced to define the rate of adopted emergency measures that have been developed by each company to reduce the undersupply of electric energy caused by emergency shutdowns. The main causes of failures were analysed. As a result, it was established that the main causes are the effects of repeated natural phenomena, as well as untimely maintenance of electrical installations. The authors primarily used the methods of numerical analysis, as well as general scientific methods of information processing. The analysed materials were visualised in the form of MATLAB diagrams. The results of the study may be of interest to technical specialists of the PAO ROSSETI electric grid companies, as well as researchers who specialise in power supply reliability.
