This research focuses on exploring various techniques and models for simulating the random behavior of energy facilities or systems. These simulations are essential in identifying the likelihood of component failures within the studied facilities. By assessing the potential consequences of emergency scenarios, this analysis serves as a fundamental aspect of synthesizing and analyzing reliability in the cyber-physical system. Ultimately, the study aims to enhance the management and control of reliability and safety for these facilities. In this study, a unified heating source is considered as an energy facility (as part of district heating systems), for example, a combined heat and power plant. However, the developed methods and models have sufficient universality for their adaptation to other energy facilities without significant changes. The research methodology is based on the use of Markov random processes and laws of the probability theory. The basic model of the energy facilities is formulated for the conditions of the simplest events flow with appropriate assumptions and constraints, in particular, ordinary events and independence of events (failures and restorations). To take into account the non-ordinary events (failures) and dependences between some failures, corresponding modifications of the basic model are proposed. A computational experiment was carried out using the developed models, and graphical interpretations of the results are presented. The obtained results allow us to formulate some preliminary conclusions about the range of influence of the simulated factors on the reliability analysis of studied facilities and to outline conditions and areas of their admissible application.

Cyber situational awareness is the result of both the analysis of cyber security and situational awareness studies and the line of research that uses artificial intelligence methods in the field of cybersecurity. It covers both methods of automatic detection of cyber threats in the network and methods of providing information to an analyst for further risk analysis and decision making to protect of the assets of the facility. Investigations of cyber situational awareness in the energy sector have become pertinent resulting from both the concept of the digital transformation of energy and the consideration of energy facilities and systems as cyber-physical systems. The problems of ensuring cybersecurity and raising awareness about the cyber environment of an energy facility are compounded by their high significance for the economies of countries. In this regard, such facilities are considered as critical infrastructure. The first part of this article discusses the basic concepts of cyber situational awareness, some knowledge representation models and some existing security metrics. The second part considers the use of frame, production and network models of knowledge representation in the analysis of the cyber situational awareness of energy facilities and the software components that implement them.

In this article we consider authors' information and computational system for energy facilities' impact assessment on the environment. The necessity of such assessments and development of this system is substantiated. We developed this system as a Web application using the agent-service approach. To develop a database for the system, we utilized ontological engineering of energy and ecology. For assessments, we developed a set of information susbsystems that use approved regulatory methods. Our system can be used for assessment of the impact of both existing and planning energy facilities and also for planning measures to reduce the harmful impact of such facilities. We also performed a set of computational experiments in order to test the developed system. Experiments have shown the correctness of the methods used, and the results of one of them are presented in the article. [ABSTRACT FROM AUTHOR]

Energy systems are key elements of critically important infrastructures, as they provide the required quality of life for the population, as well as create the necessary conditions for the reliable functioning of various branches of the economy. One of the priorities is to ensure the safe functioning of such systems, and in recent years, considerable attention has been paid to proactive safety methods. Within the framework of these methods, the main efforts are aimed at early identification of violations and deviations in the operation or maintenance of the facility. The building and use of the safety pyramid is one of the areas of implementation of a proactive approach. The paper presents the analysis of statistical data on incidents and detected violations at Russian energy facilities. The analysis made it possible to build the corresponding safety pyramids, as well as to identify that the ratio between the levels of the pyramid significantly depends on the specific type of facility. The possibility of using the safety pyramid to assess expected prevented damage in case of elimination of detected violations is also shown. Examples of assessing the value of prevented damage for energy facilities are given. [ABSTRACT FROM AUTHOR]

THE PURPOSE. The study of a fish protection structure such as a water-air curtain as an example of an ecological solution to the problem of conservation of aquatic biological resources at an energy facility.METHODS. A comparative analysis of our own research and literature data on the use and evaluation of the effectiveness of fish protection structures (FPS) has been carried out. For the selection of ichthyological samples, mesh networks of 10, 18, 22, 30 and 70 mm were used, installed in front of the water supply channels to the shore pumping stations (SPS). When analyzing the efficiency of the FPS, the methods of fish accounting are considered: the method of catching fish and the procedure for conducting observations at the facility. The assessment of fish ingress to the SPS (after the FPS) was carried out by round-the-clock observations of fish penetrating into the water supply channel in comparison with their ingress to the water-retaining rotating nets of water treatment machines on the SPS. The efficiency coefficient was determined by the difference in the concentration of fish before the FPS (at the reservoir) and after the FPS (at the SPS).RESULTS. It is shown that the efficiency coefficient of the FPS by the type of water-air curtain averaged 86.9%, which exceeds the regulatory efficiency. It has been revealed that a fish protection structure (FPS) by the type of a water-air curtain is the most environmentally friendly technical solution for water intake at power facilities.CONCLUSION. The improvement of the ecological situation in the area of the location of the RSL by the type of water-air curtain in terms of the concentration of oxygen in the water and the reduction of trophies due to the oxidation of organic substances was noted.concentration in water and of decrease in trophy due to the oxidation of organic substances.

The article discusses energy sites like real estate and their specifics and economic characteristics. As energy sites are always permanently attached to the land, according to Bulgarian law, they are equated to real estate, and the transfer of ownership must be in notarized form. Therefore, to define the energy sites in detail and derive their characteristics, they should be considered a specific type of real estate. Energy sites are subject to special supervision, and their owners can only be energy companies. Like all real estate, energy sites have the character of economic goods, as they are created as a result of human activity and to meet specific needs in society - production, transportation, storage, and distribution of energy. They are tangible fixed assets and can also be characterized as a particular type of capital and a special type of goods in rare cases [ABSTRACT FROM AUTHOR]

The paper considers spatial organization of energy facilities with an emphasis on modern practice of the Republic of Belarus. The efficiency of enterprise operation in any industry including power industry is largely due to their architectural and planning organization. Knowledge of mechanisms and specific features of the changes taking place here makes it possible to justify a promising strategy for project activities, and therefore, it allows to manage development processes of the industry and thereby avoid many negative consequences. Energy facilities are a typological unit of industrial architecture, their formation has been started due to transition of industrial production to electric energy. Today the typology shows functional approach in architectural shaping, it includes a fairly large variety of constituent units and demonstrates a tendency towards diversification. In Belarus energy facilities in the architectural aspect of their classification are limited mostly to thermal power plants operating on different types of fuel. Currently the diversification is developing in the following areas: construction of hydropower facilities (small plants on reservoirs, medium power plants, low-pressure plants, run-of-the-river hydraulic power stations), alternative energy (wind power stations, photovoltaic power stations and biogas plants) and conventional energy (thermal power plant, mini-combined heat and power plant operating on renewable fuel). The results of Belarusian practice in construction of all types of facilities (hydropower, alternative and conventional energy), peculiarities of the architectural and planning organization of facilities at the current stage, correlation with global trends in the development of industrial architecture have been characterized in the paper. The paper has determined typological features of alternative energy facility architecture, opportunities and directions for implementation of architectural approaches, problems and prospects to develop scientific support for the project process.

The object of the research underlying this article is the geoecological issues of the creation of energy facilities in Russia, and such issues are considered in the aspect of rationing. These issues have not been studied enough, while their relevance is associated with the large-scale negative impact of energy facilities on the natural environment, as well as with the designation of state rationing as one of the leading areas of research within the scientific specialty “Geoecology”. The purpose of the work was to identify the features of “geoecological rationing” in Russia by the example of the creation of energy facilities. To achieve it, the current situation concerning the geoecological aspects of rationing when creating energy facilities is considered. The stages and main problems of the formation of geoecology as a science in Russia are described (the national uniqueness of this phenomenon is emphasized). The directions of geoecological research that are relevant from the point of view of creating energy facilities, including the justification of state rationing, are highlighted. The main documents on standardization, the subject area of which affects the considered sphere of urban planning activity, are analyzed. The conclusion is made about the insufficient effectiveness of the considered documents in the geoecological aspect. The main problems of environmental regulation and standardization in the field of higher professional education in the field of “geoecology” are also identified. To rectify the situation, options are offered for performing systematic scientific studies, the results of which will be used, among other things, to update the documents under consideration.

To understand anti-democratic barriers to accomplishing energy democracy, I examine how and why a centralised energy system can maintain itself based on an ethnographic analysis of the local protest of the Miryang community against the Korea Electric Power Corporation's construction of a 765,000-volt transmission line. In doing so, I incorporate the element of authoritarian communication into the framework of peripheralization – a socio-political reproduction of social, spatial, and environmental inequality caused by siting environmentally hazardous facilities in peripheral communities and reinforcing their powerlessness – to emphasize the aggressive role of government and industry actors. Composed of unidirectional projection, partial absorption, and forceful suppression, authoritarian communication makes the sacrifices of peripheral communities enduring, and consequently enables an undemocratic energy arrangement to be resilient and perpetual. To overcome this mechanism, I highlight the active roles of citizens to contest authoritarian communication and socio-environmental inequalities as a precondition to building a sustainable energy democracy.

Worker trainers not only teach health and safety in the classroom setting but also serve informally as important peer resources on the shop floor. They are often the "go to" people, for both hourly workers and managers, when there is a health or safety question—be it about tank vapors or personal protective equipment, confined space, or specific chemicals. These worker trainers actively use health and safety resource materials, both hard copy and online. Documented here, through two surveys of worker trainers—at U.S. Department of Energy facilities, trained through the International Chemical Workers Union Council Consortium of the Worker Training Program of the National Institute of Environmental Health Sciences—is documentation of this additional contribution that worker trainers make toward safer and more healthful work places.
