One of the main tasks solved at the stage of designing workwear is the choice of materials whose hygienic properties correspond to specific operating conditions. By occupation and depending on climatic conditions, a person can be exposed to various kinds of negative and dangerous influences. Given this, this article is devoted to the study of hygienic properties and the choice of workwear materials for electric power engineers. Analysis production conditions of enterprises of the electric power industry, showed that the presence of distributed electric charges that create electrostatic fields, cause a high electrostatic hazard and negatively affect the human body. The article presents the results of laboratory tests of air permeability, hygroscopicity, moisture conductivity and thermal resistance of materials, gives recommendations for selection optimal thickness of materials for workwear and operation in hot climates. Based on the results of the analysis of works devoted to the development of clothing for hot climatic conditions, the results of thermophysical studies are given.

The article presents the results of research on the development of the structure, methods and technologies for managing the Unified Energy System (UES) of Russia in the context of the digital transformation of the electric power industry. The analysis of the experience of managing complex socio-technological systems (STS) on the example of the UES of Russia and modern achievements in digital technologies resulted in defining the main directions of the formation of a network-centric approach to ensuring the reliability of energy supply to consumers and the country’s energy security in normal operating conditions and in emergency situations. A comparative analysis of the structures is carried out and examples of practically implemented fragments of the above systems are presented. The article also presents the stratification of control loops and the structure of ontological modeling for the functioning of the entire UES control system. It defines and mathematically substantiates the algorithms for forming decisions for the managing the power facilities in the level range from of the National Crisis Management Center to the operational personnel responsible for maintaining the mode of power systems and power facilities. The given examples of operating systems, SISFEC (state information system of the fuel and energy complex) and SRMS (stability reserve monitoring systems)actually confirm the correctness of the selected solutions of the network-centric approach to managing the UES of Russia. The provisions set out in the article determine the direction in developing the digital control systems for STS.

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.

Maximum Heat

The percentage of heat pumps used in thermal power plants (TPPs) in the fuel and energy balance is extremely low in in most countries. One of the reasons for this is the lack of a systematic approach to selecting and justifying the circuit solutions and equipment capacity. This article aims to develop a new method of calculating the maximum capacity of heat pumps. The method proposed in the article has elements of marginal analysis. It takes into account the limitation of heat pump capacity by break-even operation at electric power market (compensation of fuel expenses, connected with electric power production). In this case, the heat pump’s maximum allowable capacity depends on the electric capacity of TPP, electricity consumption for own needs, specific consumption of conditional fuel for electricity production, a ratio of prices for energy resources, and a conversion factor of heat pump. For TPP based on combined cycle gas turbine (CCGT) CCGT-450 with prices at the Russian energy resources markets at the level of 2019, when operating with the maximum heat load, the allowable heat pump capacity will be about 50 MW, and when operating with the minimum heat load—about 200 MW.
