The work is devoted to solving an urgent problem - the development of a computer model of the energy consumption system of the Institute of the ionosphere of the National Academy of Sciences and the Ministry of Education and Science of Ukraine in order to solve the problem of increasing the energy efficiency of the measuring complex. The power supply system of the complex is described, a generalized structural diagram of the loads - powerful consumers of electricity is presented. The graphs characterizing the energy consumption of individual powerful loads are presented, the problem of compensating the reactive power of loads is shown. The adequacy of the developed model is confirmed by the coincidence of the shape and values of the experimentally obtained characteristics on loads with the characteristics of the model. The model adequacy was assessed by the variance of feedback deviations from the system mean. The results obtained confirmed the possibility of using the developed Matlab-model of the energy consumption system of the measuring complex for creating and testing on the model of an energy-efficient power supply system, which will ensure the stable operation of scientific equipment for the implementation of research programs of the NAS of Ukraine.

Based on the mathematical model of synchronous electric machine, basing on permanent magnets, presented in this paper, the key importance of alternator AC power sources in the form of generator (for conventional aircraft) and in the form of integrated unit starter/AC synchronous generator S/G AC (with respect to advanced aircraft concept in the field of more/all electric power MEA/AEA) was highlighted. In addition, through the analysis and selected simulations of the power supply system of a modern aircrafts, sources of onboard electrical energy (synchronous generator, integrated unit starter/AC generator) were located in board autonomic power system ASE (EPS, PES). Key components of this system are the electro-energetic power system EPS and the energo-electronic power system PES. Additionally, the analysis and exemplary simulations of key electricity sources based on mathematical models have contributed to highlighting the main practical applications in line with the trend of a more electric aircraft.

Decentralized Power Supply

В связи с интенсивным развитием децентрализованных систем электроснабжения в районах добычи нефти и газа следует ожидать появления активных потребителей, использующих для поставок электроэнергии во внешнюю сеть газотурбинные установки. При этом возникает необходимость оценить влияние активного потребителя на режимные параметры электросистем нефтегазоперерабатывающих предприятий. Целью работы является оценить возмущение режима функционирования электросистемы нефтегазоперерабатывающего предприятия при подключении активного потребителя. Цель достигается решением следующих задач: разработкой компьютерной модели электрических систем нефтегазоперерабатывающего предприятия и активного потребителя, моделированием изменений режимных параметров системы электроснабжения нефтегазоперерабатывающего предприятия при подключении активного потребителя. Переходные процессы исследуются методами имитационного компьютерного моделирования. Результаты моделирования показывают при включении методом точной синхронизации генератора активного потребителя на параллельную работу с электросистемой нефтегазоперерабатывающего предприятия нормальный переходный режим в течение 4 секунд...

The Impact

The existing centralized power supply system has the alternative due to distributed generation. By certain conditions distributed cogeneration allows to increase the reliability and quality of power supply and to reduce the cost of electricity for consumers. Therefore, a lot of energy-intensive consumers switched to their own power supply systems, as it turned out to be a competitive technical solution. The total gasification of the country’s regions and the presence of domestic manufacturers of gas turbine and gas piston power plants accelerated this process. Nowadays local power systems are emerging with cogeneration plants are the main source of heat and electricity there. The feasibility justification of the kind and type of generation is determined by many factors, including circuit-mode parameters in the local power system and adjacent network. Local power systems based on the principles of self-balance are proposed to name as energy cells. The integration of energy cells with regional power system increases the technical and economic effectiveness of power supply system for consumers. The proposed power systems transition leads to certain systemic effects. Received effects are depending on functions of distributed generation. This paper explores the impact of scheme and mode factor on the technical effects.

Today, one of the urgent problems of car operation is the problem of fuel overheating at elevated ambient temperatures, resulting in an error " fuel overheating" on the car, which in turn affects the car’s performance. This article presents research on testing fuel heat exchangers as part of a car’s fuel system by improving the design of the car’s power system. Three experiments were carried out to determine the temperature regime of the vehicle’s power supply system. Positive results of the work were obtained, which made it possible to eliminate the occurrence of the error " fuel overheating" and obtain stabilization of the fuel temperature. Keywords: power system, heat exchanger, cooling
