description Publicationkeyboard_double_arrow_right Article 2020Publisher:Tomsk Polytechnic University Authors: Sergey G. Obukhov; Igor A. Plotnikov; Ibrahim Ahmed; Vladimir G. Masolov;Relevance. The urgent task of technical and economic development of the northern and eastern regions of Russia is to provide reliable and efficient power supply to consumers, geographically located in remote, hard-to-reach areas. The use of hybrid energy systems with renewable energy sources is a promising way to solve this problem. A characteristic feature of the modes of hybrid systems, especially with a high level of fuel replacement, is the presence of ripples in charge-discharge currents of batteries used as energy storage devices. The operation of batteries in the mode of pulsed currents leads to rapid degradation of their characteristics and reduction in the service life, which leads to decrease in reliability of the power supply system and increase in the cost of generated electricity. A significant drawback of hybrid systems built according to well-known standard schemes is the inefficient use of the potential of primary renewable energy, which is especially critical for power systems geographically located in areas with severe climatic conditions. The article proposes technical solutions to eliminate the indicated problems. Aim of the study is to search for and develop technical solutions to improve the efficiency of hybrid energy systems with a high level of fuel substitution. Methods: mathematical and computer modeling using the Matlab/Simulink software environment. Results. We offer a new method of construction and control algorithm of the modes of hybrid energy systems, which provide increasing their reliability and energy efficiency. The results of the modeling and the operating modes of a hybrid power plant with a high level of fuel substitution are presented, which proves that the proposed method of construction and the control algorithm provides reliable and efficient control of the power balance of a hybrid power system in all possible operating conditions. The application of the proposed algorithm in a dual-circuit energy storage device provides 5,7 % reduction in the failure rate of the hybrid power system, increasing the operating life of the batteries by 50 %, more efficient use of renewable energy by 28 % compared with conventional methods of construction of hybrid plants.

Obukhov;Relevance. The urgent task of the technical and economic development of the Northern and Eastern regions of Russia is to provide reliable and efficient power supply to consumers, geographically located in remote, hard-to-reach areas. The use of wind power plants is a promising way to solve this problem. The primary task of the design and feasibility study of the use of wind power plants is to predict changes in wind speeds at the site of the power plant installation. The stochastic nature of the wind and its spatiotemporal variability explain the high complexity of this problem, for the solution of which the methods of mathematical modeling are used. The known models of wind speed based on Markov chains, autoregressive moving-average and other discrete models do not allow varying the time step, which does not allow their use for simulation of operating modes of wind turbines and wind energy systems. The article proposes a model of wind speed based on the stochastic differential equation which eliminates this drawback. The aim of the study is to construct wind speed model based on fractional Ornstein–Uhlenbeck process with a periodic long-term mean, which provides modeling of static and dynamic modes of operation of a wind power plant at different time intervals. Methods: mathematical and computer modeling using Matlab/Simulink software environment. Results. The proposed model, in contrast to the known SDE-based models, is able to produce autocorrelated wind speed trajectories with long-term dependence, daily and monthly variations to perform more detailed simulation of the operating modes of wind turbines at different time intervals with the required time step. The model was tested using the data of climatic observations of wind speed obtained from electronic archive of the All-Russian Institute of Hydrometeorological Information. The model adequacy was evaluated by comparing characteristics of simulated wind speed trajectories with actual observations collected at 518 weather stations located on territory of Russia.

Babich;Tariffs for energy and energy resources are the main factors determining the sustainable development of the economy. The aim of the paper is to determine and compare the dynamics evolution of the tariffs for thermal energy and the evolution of the gross domestic product (GDP).The data on the heat consumption and tariff change in the city of Chisinau were examined in monetary terms and in relative units compared to the base year 2009. The higher the tariffs, the more part of the GDP, characterized in the economy by the volume of "Output", is spent on "Intermediate consumption (PP)". The difference between "Output" and "Intermediate consumption" volumes is the "gross added value (VAB)", which is the main component of GDP. The analysis of the changes in the real GDP volume of the Republic of Moldova and the increase of the tariffs for the years 2009-2017 (taking into account the GDP forecast for 2018) show that the increase in the tariffs for thermal energy significantly exceeded the real GDP growth. Considering that the planned GDP growth is 4,7% and taking into account the change in the consumer price index (inflation rate), the calculated reduction of the thermal energy tariff in Chisinau is estimated at 28% compared to the existing value, so to 803 lei / Gcal compared to the currently regulated value of 1122 lei / Gcal. The conclusion was reached on the opportunity of applying the proposed methodology to justify current tariffs and in the near future not only extends to thermal energy tariffs, but also for other types of energy, material resources and services in the field of production and social sphere.

The problem of calculation of relay protection (RP) settings has become more urgent nowadays. The situation is exacerbated by the active implementation of renewable energy sources, FACTS, etc., which significantly change the “traditional” EPS and their operating modes. The problem can be solved by deep analysis of functioning of main elements of RP devices in the specific operating conditions and revision of coefficients used in settings calculation. That can be done using RPs detailed mathematical models and modern EPS simulators. The results of the analysis will make it possible to formulate a new methodology for setting up RP. That is a final goal. In the framework of solving this problem, the novel approach for developing RPs’ detailed mathematical models is formulated and theoretically proved. On the basis of this approach, mathematical models of the system “instrumental transformer - auxiliary transformer - analog filter” (measuring part of digital transformer differential protection) for different types of auxiliary current transformers (active and passive) and filters (Butterworth, Chebyshev, Bessel) are developed. A comparative numerical analysis of their frequency and phase responses is carried out, including taking into account the magnetization of instrumental current transformers. Summarizing, the theoretical and practical studies presented in the article allows formulating requirements for RPs’ detailed mathematical models, which will be used in the further research.

That is a final goal. In the framework of solving this problem, the novel approach for developing RPs’ detailed mathematical models is formulated and theoretically proved. On the basis of this approach, mathematical models of the system “instrumental transformer - auxiliary transformer - analog filter” (measuring part of digital transformer differential protection) for different types of auxiliary current transformers (active and passive) and filters (Butterworth, Chebyshev, Bessel) are developed. A comparative numerical analysis of their frequency and phase responses is carried out, including taking into account the magnetization of instrumental current transformers. Summarizing, the theoretical and practical studies presented in the article allows formulating requirements for RPs’ detailed mathematical models, which will be used in the further research.

Józefa Tuliszkowskiego Państwowy Instytut Badawczy Authors: SZAJEWSKA ANNA;The paper presents the assumptions for the computer simulation of a forest fire in accordance with digital topographic map of forests and short-term weather forecast. To conduct the simulation, a software has been created. The software includes deterministic mathematical model of a forest fire. Input data have been extracted from the short-term weather forecast and the digital forest maps. The application range covers both planning of a controlled fire, e.g. in cases when the fires are intentionally started by the forest services to get rid of accumulated forest material, as well as to plan extinguishing actions and to plan appropriate disposal of resources during the extinguishing of a forest fire. Creation of the described simulation environment arises from the need of optimum planning of the extinguishing actions in local fire service centers. The initial risk assessment in the stage of planning the extinguishing action, will allow efficient management of equipment by the local units. It also prevents from repeating wrong decisions made in the early stages. This need imposes limiting the use of equipment platforms to medium class PC’s. The outcomes of the paper provides accessibility of a tool supporting the decision making process and assessing the damages in the high risk conditions of a forest fire. Furthermore, conducting a simulation allows to estimate the need for fire fighting equipment in the case of total and border extinguishing of a fire, for different weather conditions, considering fire density. В работе представлены рекомендации для компьютерной симуляции лесного пожара, основанной на цифровой топографической информации о лесах и краткосрочном прогнозе погоды. Для проведения симуляции было создано программное обеспечение, содержащее детерминированную математическую модель лесного пожара. Входные данные были получены из краткосрочного прогноза погоды и цифровых карт лесов. Область применения симуляции планирование контролируемого пожара, намеренно вызванного лесными службами с целью удаления избытка собранного лесного материала, а также планирование пожаротушащих работ и распределение ресурсов во время тушения лесного пожара. Создание данного инструмента симуляции обосновано необходимостью оптимально планировать пожартушащие работы в местных центрах пожарной службы. Ранняя оценка риска на этапе планирования пожаротушащей работы позволит эффекитвно рапределять средства местными центрами и предотвратить ошибки при принятии решений на ранних этапах. Вышеуказанная необходимость вынуждает ограничить применение оборудования до персональных компьютеров среднего класса. Результат работы обеспечивает доступность инструмента, поддерживающего принятие решений и оценки потерь в условиях повышенной угрозы лесного пожара. Кроме того, симуляция позволяет оценить необходимое количество средств для тушения целой территории, охваченной пожаром или только её края при разных погодных условиях, с учётем огневой нагрузки данного участка.

S.; Kamdina, L. V.; Starodubets, N. V.;In the contemporary world, the anthropogenic effect is increasing. At the same time, the quality of life of the population is strongly associated with the environmental quality, as there is growing understanding that rising economic income does not ensure the humanity’s well-being. In this regard, issues connected with analysing the influence of the anthropogenic factor on changes in the quality of the life of the population become relevant. We believe that existing approaches to assessing the quality of life poorly reflect the current situation related to the speed of the environmental changes due to an increase in the scale and intensity of its pollution. Therefore, for assessing the quality of life, we suggest taking into account the environmental and energy components of the anthropogenic factor. To this end, the classification of anthropogenic factors is supplemented by the “industrial production” group, distinguished by the “source of impact” indicator, which allows analysing the group’s influence on changing parameters of the quality of life of the population. The methodological basis of the study is a comprehensive approach to assessing the quality of life. Based on it, we structured the stages of the evolution of approaches to measuring and assessing the quality of life of the population. Moreover, we described key features of these approaches, and identified the fourth stage that substantiates the priority of environmental and energy criteria in assessing the quality of life. We propose to improve the methodology for assessing the quality of life of the population by introducing additional environmental and energy characteristics. The article presents the results of using this improved methodology. We tested it on the examples of the Sverdlovsk and Chelyabinsk regions. The obtained values of the integral indicators of the quality of life of the population show that the Sverdlovsk region has lower index values. That happened due to a more developed industrial sector and, as a result, the more deteriorated environmental situation. The proposed methodology for assessing the quality of life of the population can be used by regional leaders for making decisions related to the regional development aimed at improving the quality of life of the population. © 2019 Institute of Economics, Ural Branch of the Russian Academy of Sciences.

S.; Starodubets, N. V.; Yachmeneva, A. I.;One of the important problems of the environmental economics is the development of methodology for quantifying the assimilative capacity (AC) of a territory. The article analyzes the existing approaches to determining and assessing the AC of a territory. We justify the advantages of using the energy approach. The authors' method consists in using the maximum permissible energy load (MPEL) for quantitative assessment of the AC of a territory. MPEL is a value that the ecological and economic system can withstand for a long time without changing its properties. We determine MPEL on the basis of data on the ability of various categories of land to absorb greenhouse gases (GHG), as well as the specific GHG emissions per ton of conventional fuel. Further, we compare the calculated value of MPEL in fuel equivalents with the actual consumption of fuel resources for the needs of the national economy. These values ratio can serve as a standard for measuring and balancing the environmental and economic system. The authors have validated the described method on the example of the Sverdlovsk region, which is characterized by a high level of man's impact. Calculations show that the actual consumption of fossil fuels in the region exceeds MPEL. That indicates an imbalance in the ecological and economic system and may lead to further deterioration of the environmental quality in the region. The proposed methodological approach and calculations can be used when developing strategic planning documents for a territory, including its energy strategy.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article , Other literature type 2019Publisher:Zenodo The analysis of the world electric-energy balance revealed the advantage of steam turbine plants. An increase in their efficiency through the improvement of the initial parameters runs into difficulties associated with creation of new materials. The efficiency increase that results from the final pressure reduction requires an improvement of the circulating water supply system. The aim of this work is to determine the effect of the water-cooling tower on the electric power station profitability. This goal was reached by the creation of a mathematical model of the water-cooling tower and turbine plant with a condenser connected to each other. The calculations were made for two types of cooling tower fill packing: asbestos cement sheets and mesh elements made of polyethylene. Further, according to it, the vapor condensation temperature was determined. The latter affects the vapor discharge in the condenser, the capacity of the turbine plant and the temperature of the cooling water at the condenser output, i.e. at the cooling tower input. The novelty of this work consisted of consideration of the interaction between the cooling tower and turbine plant. Significance of the obtained results lies in the fact that, taking into account the reciprocal influence of the turbine plant and cooling tower, the efficiency of the fill packing replacement turns out to be major comparatively to the case without considering this influence. The replacement of the fill packings the half-a-year average temperature of condensation will become lower by 2.34 °С, electricity production increases by 41.72 GWh.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article , Other literature type 2019Publisher:Международный научно-исследовательский журнал Authors: Duisenbaeva; V S Balandin; T N Shaigaraeva; E G Neshina;The authors analyze the heating networks of housing and communal services in the paper. Applying the queuing theory, the assessment of the systems performance under certain specified criteria is made by searching for optimal system performance. The most critical elements of heat distribution to the consumer are pipes, which should be sufficiently strong and tight at maximum pressures and temperatures of the coolant. The authors considered the question of the possibility of calculating the planned cost of services of a vehicle operator, in which the volume of services is determined based on the capacity of the central heating center. В данной статье авторы проводят анализ тепловых сетей ЖКХ. Применяя теорию массового обслуживания, проводят оценку работоспособности системы при определенных заданных критериях и поиском оптимальных характеристик работы системы. Наиболее ответственными элементами распределения тепла к потребителю являются трубы, которые должны быть достаточно прочными и герметичными при максимальных давлениях и температурах теплоносителя. Авторами рассмотрен вопрос о возможности расчета плановой себестоимости услуг оператора ТС, у которого объемы услуг определяются исходя из пропускной возможности ЦТП. №11(89) (2019)
