The choice of the optimal layout of prefabricated water pipelines is determined after technical, economic and hydraulic calculations of the entire water intake, taking into account the characteristics of wells and deep-well pumps installed in them, and the parameters of all pressure pipelines. Hydraulic calculations are based on a developed mathematical model of water intake, which should provide reliable data on pump flows, drops in water levels in wells, flow rates and pressures in the collecting water pipeline system for any number and combination of operating wells. This allows for the correct selection of pumps and reduces energy costs for lifting and transporting water. The article is devoted to the development of a methodology for hydraulic calculation of group well water intakes with paired collection water pipelines, which are used at high-capacity water intakes in water supply systems with a high degree of water supply security. The difficulty in calculating such water intakes lies in the fact that here each well simultaneously supplies water to two strings of collecting water pipelines, which distinguishes this scheme for supplying water to a collecting unit from other standard schemes. The article presents calculation schemes and an algorithm for hydraulic calculation of group water intake, which is considered as a system with non-fixed water supplies. The calculation algorithm is based on taking into account the balance of pressures in water pipelines with pumps included in them and the balance of flow rates in nodes for all sections of prefabricated water pipelines. A computer program has been developed and the results of a numerical calculation of groundwater intake, equipped with paired prefabricated water pipelines and consisting of 15 wells, are presented.","PeriodicalId":52141,"journal":{"name":"Energetika.

When optimizing the operating modes of mini-CHPs using LFT and operating in parallel with the UES, which has a significant surplus of electricity generating capacity, it is necessary to separate options for existing stations and options for newly built ones. In the first case, due to the fact that  the power of the equipment is known, it is advisable to consider two extreme options, i.e., the operation of the heating unit according to an electrical or thermal load schedule. In this case, in order to maintain the daily consumption traffic it is necessary to provide for the accumulation of thermal or electrical energy, respectively. In the case of new construction, the optimized parameter is the power of the generating equipment, so it is advisable to give preference to the option with the maximum number of hours of use of the rated power. In order to increase the economic attractiveness of mini-CHP, options for developing the structure of mini-CHP using LFT with the transition to multi-generation technologies and adaptation to the existing operating conditions of the UES of Belarus have been considered. The results of an analysis of commercially available technologies for storing excess electrical energy are presented in accordance with current and projected (until 2030) cost and operational indicators. For adapting mini-CHP to operate in the UES in conditions of a surplus of electrical power capacity, an electrical energy storage system using hydrogen as an intermediate energy carrier is of greatest interest. To utilize the excess electrical energy consumption from a mini-CHP with a heating ORC unit during the daily dips, a structural diagram configuration using an alkaline electrolysis module for hydrogen production is proposed. The efficiency of energy storage and use technology is considered depending on the specific energy intensity for various electrical energy storage technologies. The use of the two most energy-intensive energy storage technologies is proposed: accumulation based on electrochemical batte-ries and the “electricity-hydrogen” type. During the study, an analysis of the functioning of the ORC-installation Turboden 14 CHP ORC-installation operating as part of a mini-CHP using LFT was carried out. It was revealed that today the installation operates in a wide range of load changes (from 17 to 87 % of the rated electrical power), while the generation of electrical energy from thermal consumption varied in the range from 0.20 to 0.026 MW/MW.

The growth of the battery market in the last decade has been 20-30%. One of the ways to increase the efficiency of an electric power storage device is its hybridization, i.e. the use of heterogeneous battery units. The paper examines the features of passive coupling of lead-acid and lithium-ion batteries in a hybrid storage device. A model is presented for calculating the electrical characteristics of these units during operation. The possibility of choosing a hybrid drive structure that provides a comparable operating voltage range of the units (operation without voltage converters) is demonstrated. The modes of operation of a hybrid energy storage system are modeled both for simple parallel connection and for switching blocks according to a threshold algorithm. It is demonstrated that in order to equalize the discharge rate of the main and additional units, it is necessary to coordinate the capacity of the ESS, the degree of hybridization, the type of load and the electrical parameters of the batteries, which is impossible without modeling the system. When the threshold switching of the blocks takes place, additional control parameters, making it possible to change the discharge rate of the additional block and increase the economic efficiency of the hybrid ESS. Estimates of the economic efficiency of hybrid ESSs have been made for different values of the threshold switching voltage of the lithium-ion unit, as well as for three characteristic loads: an electric forklift truck, a 30-apartment apartment building and a 300-apartment residential complex. The results demonstrate the features and technical and economic potential of passive hybridization, can be used for the design of hybrid ESSs for small power systems with solar and wind power plants, in the calculation and design of generator – storage – consumer systems.","PeriodicalId":52141,"journal":{"name":"Energetika.

Due to its global nature, the main influencing factor affecting the technical condition of any steel underground pipelines, including gas pipelines, is corrosion, primarily soil corrosion. To protect against it on pipeline networks, along with insulating coatings, electrochemical protection (ECP) is applied, that is, following the definition of STO [Standard of Organization] 17330282.27.060.001–2008,  protection of metal against corrosion in an electrolytic environment, carried out by establishing a protective potential on it or eliminating the anodic potential shift from the stationary potential. In the gas distribution industry of the country, methods and means of electrochemical protection have been applied since the beginning of gasification and the construction of the first gas pipelines. All gas supplying organizations of the State Production Association for Fuel and Gasification “Beltopgaz” (six regional and Minsk city), which operate gas distribution facilities, have specialized corrosion protection services. These services provide maintenance of available ECP equipment, conduct electrical measurements on gas pipelines and corrosion studies of soils, and have certified laboratories. This paper is devoted to the analysis of domestic experience in organizing electrochemical protection of steel underground gas distribution pipelines, searching for promising directions for its improvement and increasing efficiency through the implementation of a unified industry technical policy, automation and telemechanization of ECP equipment in the general context of digital transformation, optimization of the timing and volume of maintenance.","PeriodicalId":52141,"journal":{"name":"Energetika.

Equipment is known for monitoring emissions from small-diameter chimneys, but for large-diameter pipes (15 m or more) available in our Republic, there are no corresponding technical solutions.  The paper examines the problem of automating the sampling of flue gases based on an electric drive in large-diameter chimneys. To ensure the optimal trajectory of the sampler in the chimney section, it is necessary to use an asynchronous electric motor with a frequency converter and a position sensor. A functional diagram of the control system is proposed, which contains a programmable logic controller for generating the motion mode, as well as a method for calculating parameters and expressions for generating a task signal for continuous sampling mode. Since the range of speed control increases as the diameter of the chimney increases, depending on it, scalar or vector frequency control can be applied. An expression is proposed for calculating the optimal value of the parameter N of an incremental position and speed sensor (encoder), which contributes to a reasonable choice of sensor. The results of simulation modeling are presented, confirming the effectiveness of the proposed method for calculating the parameters of the sampler drive.","PeriodicalId":52141,"journal":{"name":"Energetika.

Such emitters can be used in the energy system of low-mass satellites as a source of jet propulsion. The dependence of the thrust of a micromotor on the electrical power supplied to it was experimentally studied, which made it possible to determine the most efficient operating modes of the microthruster. This is of interest from the point of view of increasing the energy efficiency of the latter in conditions of limited power availability of low-mass satellites. It was found that the characteristic “electric field voltage – emitter thrust” is non-monotonic with a pronounced maximum, which imposes restrictions on the magnitude of the electric field in the emitter. To explain the limit of emission intensity, a diffusion-convective model of ion movement inside the capillary was constructed. The main idea of the proposed model is the assumption that the intensity of ion emission is determined by their concentration at the outlet of the capillary, and the velocity of the emitted ions is higher than the velocity of flow of the ionic liquid in the capillary as a continuous medium. Moreover, the acceleration of ions at the outlet of the emitter increases nonlinearly with increasing external forces. The decrease in the concentration of ions as they are emitted must be compensated by their diffusion inside the capillary and convective flows, the velocity of which is limited. The constructed system of equations is analyzed numerically. For the system of Navier – Stokes equations, the projection method proposed by Chorin is applied. Based on the known velocity field, density, and concentration distribution, a time step is taken for the equations of motion. Then, taking into account the found velocity, a time step is taken for the convective diffusion equations and the density field is recalculated. The created code made it possible to confirm the possibility of the existence of a maximum mass flow rate of ions, i.e., micromotor thrust, which is in qualitative agreement with the experimental data. The main factor on which the magnitude of the maximum and its position depend is the degree of nonlinearity of the coefficient responsible for the acceleration of ions at the outlet of the capillary.","PeriodicalId":52141,"journal":{"name":"Energetika.

The emergency component of the short-circuit current is defined as the difference between the vectors (sinusoids) of the main harmonic of the short-circuit current and the current of the previous mode, if the effective value of this difference exceeds some predetermined value.

The experience of Western European countries in terms of the transition to “4th and 5th generation” district heating systems is considered. The technical aspects of the creation of hybrid control systems are analyzed, generalized structural technological schemes of hybrid district heating systems and the main measures, the implementation of which is necessary during their transition to the state of a new generation of district heating systems, are introduced. It is noted that the hybridity of the district heating system implies the presence of regenerative properties in terms of the production of energy carriers for use in adjacent systems, in particular hydrogen. In turn, the flexibility of the district heating system is largely realized via the development of accumulative properties, which leads to the invariance of the use of available energy storage technologies. It is argued that, despite the constantly decreasing costs of creating and operating an electric power storage system, thermal energy storage systems remain a priority in heat supply, especially when using renewable energy sources. The issue of using electricity in district heating systems as an excess resource of integrated energy systems within the framework of equalizing the daily and seasonal schedule of energy consumption is also considered. Also, a diagram is presented reflecting the technical solutions in terms of the equipment used to implement the “electricity – heat” technology. The problem of management of heat supply systems of a new generation is discussed. It is indicated that in order to ensure the required maneuverable properties of heat supply systems, it is necessary to develop and apply new methods of planning and managing heat supply systems, excluding a single-purpose approach in the organization of hybrid systems, which manifests a synergistic effect with new possibilities for finding optimal solutions aimed at reducing fuel consumption. The need to create an intersystem information space, which would include the creation of intelligent process control systems based on the analysis of large amounts of data, is demonstrated. It is noted that the main goal of operational management of hybrid thermal networks is to achieve a dynamic balance between the required value of the thermal load of consumers, the production of thermal energy and the volume of accumulation. The use of hybrid systems in heat supply makes it possible to solve the multifunctional task of increasing the reliability of energy supply and the stability of the functioning of the energy system, which is primarily achieved by solving the problem of balancing production and energy c","PeriodicalId":52141,"journal":{"name":"Energetika.

The issues of dynamic processes of development of micro- and nanojointing structures of a fractal type from stress points in the solid material/metal of the internal chamber with the working substance of energy devices under conditions of different modes of their functioning are considered. At the same time, regularity, determinism and stochasticity can be realized according to various well-known scenarios, which is illustrated by the example of a number of modes. The possibility of dislocation development and reversibility of such processes, such as the formation of inhomogeneities and cracks, is also discussed. The modifications and development of the 3D fractured structure in the material are analyzed using simple analytical relations with the corresponding topological mappings inside the material with the emergence of fractal objects on the surface of the chamber. Although the analysis carried out is a model in the general formulation with known representation algorithms, nevertheless it is based on relevant physical principles and has obvious practical significance in terms of determining trends and directions for assessing the reliability and durability of such installations. All this makes it possible to qualitatively assess the trend in the development of instabilities and defects, which can eventually lead to the destruction of the solid-state working chamber of various power plants. The availability of a reliable database of their characteristics and operating modes of the working substance in real conditions with numerical parameters should allow, within the framework of the considered concepts, to fulfil predictive modeling and prediction of the durability of safe and stable operation of such devices and control their modes, taking into account appropriate metrological support.","PeriodicalId":52141,"journal":{"name":"Energetika.
