Abstract

   The authors have developed an autonomous hydrogen energy complex and analyzed its economic efficiency. The developed energy complex is multifunctional. The main result of the work is the production and supply of electricity to the power system during high load hours. In addition, low-power steam turbines included in the energy complex can provide plant-wide backup for the NPP’s own needs in the event of a station blackout: based on experimental data from the Balakovo NPP, it was previously shown that one power unit with a low-power turbine using the energy of the decay heat of the reactor can, if the connection between the NPP and the power system is broken, provide electricity to several power units for a long time. Thanks to the installation of low-power turbines as part of the hydrogen energy complex, their constant heated state and self-sufficiency will be ensured by generating electricity into the power system or for their own needs in normal mode. The work discusses options for installing an autonomous hydrogen energy complex with and without replacing expensive external heat exchangers of the passive heat removal system of the reactor core. The efficiency of an alternative option without installing a storage system with the sale of off-peak electricity to the power system, which is used to produce hydrogen/oxygen by electrolysis, depending on the tariff for off-peak electricity, is also calculated. Due to the lack of operating analogues of the hydrogen energy complex, several options for proposed capital investments were considered. The results of the study revealed that replacing expensive equipment of a passive heat removal system significantly increases the economic efficiency of the proposed redundancy system. For the accepted capital investment options, the boundary values of the off-peak selling tariff for electricity are shown, at which the use of a storage system is more effective in comparison with the sale of nighttime electricity to the power system.

Abstract

   The article outlines a number of problems associated with the teaching of foreign languages in the specialty at the technical higher educational institutions of Turkmenistan, as well as with the development of the professionally oriented textbooks and teaching aids. A set of exercises and special level assignments for the texts is proposed. A model for improving the quality of teaching of foreign languages at the technical higher educational institution and the educational activities of the Department of Languages of the State Energy Institute of Turkmenistan at the stage of transition of higher educational institutions in Turkmenistan to the Bologna system is described. The assertion is substantiated that the proposed model of educational activities of the teachers will help improve the linguistic and professional competence of the students, retrain foreign language teachers in a short time according to the educational program of a technical higher educational institution; the introduction of the innovative pedagogical technologies into the educational process, the creation of high-quality textbooks for the energy engineers in English, Russian, Chinese, German and Persian languages in their specialty, the use of testing technology to monitor the students’ knowledge, the creation of software and test banks in professional foreign languages.

Abstract

   Today, all robots in industrial enterprises are controlled by specialized software. When these robots are developed and maintained by software companies, installing special codes on them creates certain difficulties. This is why higher educational institutions use the latest achievements of science, digital technologies, “smart” devices and innovative devices; one of the main tasks of our time is to collect more extensive and rich information, and explain it to students in the Turkmen language for practical classes in higher educational institutions of Turkmenistan. For this reason, a scientific project called “Drawing Robot” is being conducted to train students in practical classes in the course “Programming languages and methods”, “Technical means and methods of information security”, “Hardware and software for information security”, owned by Department of Information. Technologies of the State Energy Institute of Turkmenistan. This scientific article, based on the results of this work, presents some information for educational purposes when teaching students programming rules, program codes and connection devices. As an example, this article describes the sequence of work on teaching students to program robots and execute commands in the Turkmen language in accordance with government programs.

Abstract

   In this paper, certain issues envisaged in the framework of development of design methodology for intelligent autonomous distributed hybrid power complexes (ADHPC) with green hydrogen and energy storage, functioning in grid mode and in the mode of interaction with the global (national) grid (GN) have been solved. Depending on their energy deficit or surplus, relative to the global grid, ADHPCs can operate as a load or as an energy source, respectively, as follows: - based on the analysis of the energy balance management process in the ADHPC, a reasonable choice of the structure of the system of accumulation and distribution of power flows (SADCF) was made from the point of view of increasing the reliability of its functioning and ensuring the physical feasibility of the energy balance management process in this structure, i.e. keeping the actual power consumption of the consumers close to the required rated power at each given time t. This is achieved by including a condenser connected to the SADCF system on its assembly and distribution bus and a storage system BS with double-level ((BS1, BS2), double-circuit ((BS1(1), BS1(2)), (BS2(1), BS2(2))) structure, whereby: BS1of the level 1 - to manage the capacity balance in the SADCF under normal ADHPC regime and the variation of green hydrogen and consumption capacities within their confidence intervals assessed at the design stage; BS2 of the level 2 - to coordinate ADHPC and GN modes of operation and to control, together with BS1 of the level 1, GN, diesel generator (DG), the power balance in the SADCF when the ADHPC fails and when RES and consumption power are outside their confidence intervals; alternating charge/discharge operation of the parallel circuits will extend the life of the BS system; – a comprehensive definition of optimal ADHPC system situational energy balance management task is formulated.

Abstract

   The article examines the issue of modern challenges in the development of the fuel and energy complex, including the oil and gas industry as its basis in terms of the volume of tax revenues to the budget. Industry technological priorities have been identified: the creation of domestic equipment and technologies for the traditional fuel and energy complex in the upstream sector, digital transformation and the development of Industry 4.0 technologies, the development of technological competencies in key areas of the energy transition, and the development of technologies in terms of ecology and industrial safety. The world experience of supporting the development of scientific research in industry is analyzed using the examples of the USA, Norway and China. An analysis of the challenges of institutional development of the fuel and energy complex at all stages from research to serial production is presented. State covenants have been determined in the field of human resources development to implement the energy transition of the domestic fuel and energy complex, independent of external circumstances. Based on the analysis of internal barriers and successful international practices, proposals were made for the development of state technology policy.
