In the modern conditions of the development of the electric power complex, relay protection and automation devices play a special role related to protection against possible damage resulting from violations of normal operating modes, both of individual elements and the entire power system as a whole. This, in turn, directly affects the reliable and stable functioning of the main power elements and electrical equipment. Damage to the power part of the equipment of an electric grid complex can be caused by changes in the main parameters of the normal mode: a change (increase) in currents leads to overloads and, in the limit, to short circuits, a decrease in voltage leads to an avalanche of voltage and disruption of the operation of electric motors connected to the damaged section, and an increase in voltage leads to overvoltages in certain sections. In addition, violations associated with a decrease in the transmitted active power lead to a change in frequency, and a violation of the reactive power balance leads to a change in voltage in certain sections, which generally leads to noncompliance with the power balance and loss of stable operation of the power system. The main reasons for failures in operation, false and excessive triggering of microprocessor relay protection devices are considered. The main ways of solving the problem of electromagnetic compatibility in the electric power industry are identified. A solution is proposed to improve the reliability of the operation of microprocessor relay protection devices and the way of development of the problem of electromagnetic compatibility in the electric power industry is shown.

Subject. This article deals with the issues relating to improving integrated reporting in terms of dovetailing strategic objectives with capital changes. Objectives. The article aims to develop a system of indicators for disclosure of capital types in integrated reporting of electricity generating companies, as well as recommendations aimed at implementing the fundamental concepts and guiding principles of integrated reporting. Methods. For the study, we used the methods of analysis and synthesis, comparison, generalization, and abstraction. As a case study, we conduct a comparative analysis of the disclosure of six types of capital by the largest electricity generating companies, namely PAO Inter RAO, AO Rosenergoatom and PAO RusHydro. Results. The article formulates proposals for disclosure of capital information to address such a lack of accountability as a contradiction to the principle of coherence. It proposes a system of indicators (core and additional) for disclosure of six types of capital by electricity generating companies. Conclusions. A significant reporting problem is the lack of correlation between key strategic objectives and capital changes. The formulated recommendations for disclosure of capital information can help solve this problem, and increase the attractiveness of the integrated report for capital providers.

The digital economy implies a structural transformation in many industries, including the energy sector, without taking into account the state specifics of the industry, for which full-fledged digitalization can be harmful. The aim of the study is to develop a methodology and determine the readiness of countries for digitalization in the electric power industry, taking into account all the main industry groups of factors. The paper analyzes the concept of “energy transition” and defines the indices that are applied to assess this transition at the global level. A system of indices is proposed to determine the degree of readiness for a digital transition in the electric power industry as one of the components of the “energy transition” and the most possible scenario for the transformation of this industry in Russia. The analysis of key areas of digital energy development is presented. The degree of readiness of the leading 100 countries in terms of GDP for digitalization in the electric power industry according to the proposed methodology has been calculated, and the further direction of basic research in this direction has been indicated. Conclusions have been drawn on the appropriateness of developing state programs and the main directions to which DM decision should be drawn with due desire to digitize the industry have been highlighted.
