The energy system of most industrially developed countries is being transformed into an intelligent energy system with the introduction of digital technologies. Training of specialists in the field of intelligent control systems for operating modes of electric power complexes dictates the need to develop educational laboratory installations from domestic manufacturers with elements of artificial intelligence. The purpose of the project is to develop an educational and research complex with elements of artificial intelligence for performing laboratory work in the discipline «Intelligent means of controlling the modes of power supply systems». Methods: a method for calculating network parameters in complex networks was used. When developing the software part, flexible methodology (AGILE) was used. When developing a neural network algorithm, a supervised learning approach and a regression algorithm were used. Results: when carrying out the work, measurements were taken of the parameters of the initial data of physical laboratory stands «Model of an electrical system with a complex load unit» of LabSys LLC, «Automation of electric power systems» of LabSys LLC. A digital twin of the laboratory stand was created, supplemented with virtual objects of electric power systems with adjustable parameters and means of controlling the modes of power supply systems. A neural network was trained to recognize the mode of the power supply system corresponding to minimal losses during the transmission of electricity. Practical significance: the educational and research complex includes educational and methodological support for full-time, remote and mixed implementation of laboratory and practical work in the discipline «Intelligent means of controlling the modes of power supply systems». The digital twin of the educational and research complex allows you to gain knowledge, skills and abilities in the design, programming and operation of intelligent control systems in the electric power industry. The neural network allows you to optimize losses at the current values of the parameters of the complex load.

Keywords: electric power industry, neural network, digital twin, active-adaptive electrical network, power losses, intelligent control.

The use of programmable logic integrated circuits (FPGAs) is becoming more common due to the growing interest in machine learning and augmented reality technologies, which place high demands on computing resources. The performance of an FPGA is determined by its architecture, which affects chip characteristics such as performance, footprint, and power consumption. The versatility of FPGAs is achieved due to the possibility of reprogramming their basic logic element. A typical basic logical element includes truth tables (Look-up Tables or LUTs). The more basic logic elements are used to create an FPGA, the larger the die area becomes. Each base gate contains a truth table that performs a single logic operation. However, since not all transistors in the LUT are used, this can result in inefficient use of on-chip space. In earlier studies, a solution has been proposed that allows a single truth table to perform multiple functions at the same time. This leads to a decrease in the number of required basic elements and, consequently, to a decrease in the area occupied on the FPGA chip. The aim of the study is to develop the topology of the LUT truth table of the basic FPGA logic element, which implements several functions simultaneously for a different number of variables. Research methods are based on modeling the developed topologies of the proposed LUT with the measurement of characteristics in terms of chip area, the number of transistors used, power consumption and maximum delay. The simulation of the proposed LUT was carried out in the Microwind ASIC design system for three, four, five, and six variables, in which two to four functions are implemented. As a result of the study, the efficiency of the proposed LUT topology for three, four, five, and six variables has been demonstrated. The dependences of the area, the number of used transistors, power and delay on the number of implemented functions are given. It also compares the performance with the simulation of the known LUT, which implements only one function.

Keywords: FPGA, LUT, transmitting transistors, truth table, logic function, topology.

Losses of electricity during transmission are inevitable and standardized. Excessive losses are a direct economic loss for network companies, so reducing losses is an important task, for which many methods have been developed. The article presents current methods for reducing electricity losses. Despite the widespread use of various methods of combating electricity losses, their level in the electrical networks of the Russian Federation remains quite high. Electricity losses are divided into commercial and technical. Technical losses consist of load power losses and no-load losses. When adjusting the voltage level, these losses change. Purpose: development a method for reducing electricity losses by selecting the optimal voltage of the electrical network using the method of penalty functions. Methods: creation of a special algorithm to determine the optimal voltage level of the electrical network, ensuring a reduction in electricity losses during its transmission and distribution. Optimization is carried out by the method of penalty functions. Results: an analysis was made of the dependence of electricity losses on the voltage level in the electrical network. As the voltage increases, load losses increase, and no-load losses decrease and vice versa. Thus, by regulating the voltage within the permissible range, it is possible to reduce electricity losses. This paper presents an algorithm for selecting the optimal voltage using the penalty function method, which ensures a minimum of electricity losses. An objective function and a penalty function have been developed. A calculation of one feeder of a 10 kV electrical network was carried out, power flows at the beginning and end of the line, voltages at network nodes, as well as load losses and no-load losses in each element of the electrical network under consideration were determined. The optimal voltage was selected for three different modes. The possibility of reducing the level of electricity losses when using this optimization method is shown. Practicalrelevance: the developed method can be implemented and used by electric power companies to reduce electricity losses in high voltage electrical networks.

Keywords: energy efficiency, power losses, voltage regulation, optimization, power supply, penalty functions, electric networks.

The development and implementation of an unmanned mining dump truck into open-pit mining technology is an integral part on the path to creating an automated mining enterprise. It does not seem possible to adapt existing systems that ensure vehicle movement in unmanned mode for a mining dump truck due to the design features and operating conditions. In this situation, the developer of a control system for an unmanned mining dump truck should be helped by a simulator that allows them to simulate the operating conditions and design features of a mining dump truck in terms of installing sensors on board. Purpose of the work: to justify the choice of a simulator for conducting a study of the operation and interaction of autonomous control systems of an unmanned mining dump truck based on multi-criteria analysis. To carry out multi-criteria analysis, alternatives are assessed against a number of criteria using the TOPSIS method. The most accessible simulators of the control system for unmanned vehicles were selected as alternatives, and the formed requirements for the control system for an unmanned mining dump truck were used as evaluation criteria. Distinctive features of the placement of sensors on a mining dump truck have been identified, as well as features of the environment during its movement, on the basis of which the requirements for the simulator used in training neural network algorithms for control systems of created unmanned mining dump trucks have been formulated. Results: based on the obtained analysis results, the CARLA simulator was selected for further scientific research in the development of a mining dump truck control system. It is worth noting that this simulator allows you to create terrain maps and simulate the operating conditions of a mining dump truck at a mining enterprise. One of the main tasks of further research in this area is to determine the influence of the number and installation locations of sensors on the field of view around an unmanned mining dump truck, as well as to prepare data for training neural networks and the environment perception subsystem.

Keywords: autonomous control, simulator, unmanned dump truck.

The basis of the nature-like proportionality in the article is based on the scientific hypothesis about the dominant ratio of the velocity circulation and acceleration of the flow flowing around the profile of the fan impeller blade, as an aerodynamic analogy of the energy conversion mechanism of the rotating fan working flow and the "waving wing" of birds. The purpose of the study: to develop a methodology for designing aerodynamically adaptive fans with a dominant natural similarity for air cooling devices in order to increase the competitiveness of enterprises in the oil and gas industry of the Russian Federation. Methods: the novelty of the research made it possible, on the basis of the above hypothesis using Helmholtz, Cauchy, Kelvin theorems, hydrodynamic analogy of geometric and kinematic diffusivity, modification of the Zhukovsky-Chaplygin-Kutta formula in relation to profiles with sources on their surface, to obtain a mathematical model for calculating additional circulation and the coefficient of nature-like proportionality from the source parameters. Fans created on the basis of the principle of nature-like proportionality are characterized by the fact that they adequately and simultaneously with minimal energy costs create the necessary parameters of cooling air in heat exchangers, implement the concept of optimal ecological technology of subsurface use. Results: it has been experimentally shown that the coefficient of natural proportionality is an analogue of the integral aerodynamic quality of the fan impeller blade profile. The use of the developed mathematical model made it possible to design a profile with distributed sources that has a 45% higher value of the coefficient of nature-like proportionality and, accordingly, the integral coefficient of aerodynamic quality in the range of operating modes of the angle of attack from 0° to 20°.

Keywords: nature-like proportionality, profile, grid, fan, energy efficiency, jet flow control, circulation, source, adaptability, dominant.

Nowadays, oil plays a big role in everyday life. The issue of increasing the efficiency of oil production is becoming more and more relevant every year in Russia and around the world and today is one of the important tasks. An oil field usually has many different wells with different flow rates, diameters and depths. Oil also has different viscosities and different dynamic liquid levels. These circumstances significantly complicate the process of oil production, especially if there are a large number of wells, due to the need to calculate and design a specific pumping unit for each of them, driven by a specific, also calculated and designed, engine. This article proposes a progressive way to solve the problem that has arisen, practically not presented in the literature before. The purpose of the research: to investigate the possibility and feasibility of using a universal engine for installing an electric centrifugal pump for the purpose of oil production at any type of wells that exist in the field, as well as to carry out its calculation and design. Methods: taking into account the results of the study and assessment of the state of the oil industry, an analysis of the functioning of a real oil field is carried out in order to determine the feasibility of using a universal engine in its wells. The parameters are calculated and the standard size of a pumping unit for oil production is selected for the subsequent design of a universal asynchronous motor. Results: research has confirmed that the use of a universal asynchronous motor in oil production at various wells is advisable. The use of such an engine will reduce material and financial costs for logistics, maintenance and repair of equipment used in oil production fields. Practical significance: based on real data from the oil and gas production shop No. 8 of Lukoil-Perm LLC, which represents well parameters and oil characteristics, the installations of an electric centrifugal pump and the corresponding parameters of asynchronous motors were calculated, and the parameters and characteristics of a universal asynchronous motor and Its design was carried out in order to increase the efficiency of oil production.

Keywords: oil production, well, asynchronous motor, electrical network, installation of an electric centrifugal pump, universal electric motor.

E-commerce is one of the highest priority areas in trade, the development of which has been facilitated by the Internet. Significant benefits are provided to both producers and consumers through the sale of goods via the Internet. For manufacturers, one of the priority areas in business management is the ability to sell goods online. The expansion of the customer base, the entry into new sales markets, the collection of analytics, and the making of objective management decisions are enabled as a result. For consumers, the availability of real-time access to the catalog and delivery times of goods is considered to be important, especially for large enterprises, given the significant dependence of business efficiency on delivery times. One of the key trends in the development of the sale of goods via the Internet is the integration of e-commerce and ERP-class information systems, which enables the automation of current business processes and the more efficient management of company resources. Purpose: An analytical review and study of the current level of integration between ERP and e-commerce. The results of the literature review are presented, aiming to examine the current state of the level of integration between the two management tools, providing improvements in the efficiency of procurement activity management, resource planning, and service consumer operations. Additionally, possible methods of integrating ERP and e-commerce, their advantages, disadvantages, and integration requirements have been analyzed. Practical relevance: the establishment of insufficient elaboration of the tasks of integration between e-commerce and standard modules of an ERP-class information system, which is necessary for the implementation of applied software development.

Currently, automatic frequency shedding (AFS) is used, which, when there is a shortage of active power in the power system, works by sequentially disconnecting specified load volumes (clusters). Reduction of risk of erroneous determination of cluster size is achieved by comparison and ranking of power supply objects by reliability and efficiency of their operation. The difficulties of ranking are due, first of all, to the diversity of types, and secondly, to the difference in units and the variability of data. The purpose of the study is to develop a methodology for calculating the priority of disconnecting oilfield consumers when there is a shortage of active power in the energy system, taking into account the possible risk of failures of electrical grid equipment. Methods: the initial information is the statistical data of operation on failures of the main electrical network equipment. Assessment of probabilities and time of staying in various states of disturbance of normal power supply mode (NPSM) in the absence of a technological reserve is performed on the basis of stochastic Markov circuit model. Results: a graph of the Markov process of the occurrence of NPSM with a predefined state space was developed.
A methodology has been developed for calculating the priority of disconnecting consumers when there is a shortage of active power in the power system, based on a ranking approach. This technique allows you to rank objects of the same name and establishes the relationship of features by calculated rank correlation coefficients. A quantitative assessment of integral indicators was carried out, including a number of cumulative data, the processing of which is difficult. To calculate the final integral indicator of the priority of disconnections of oilfield consumers in the event of a shortage of active power in the energy system, an integral indicator was used, which is the relative sum of ranks. Practical relevance: the developed methodology realizes the possibility of creating a programmable AFS, which allows you to more accurately determine the value of disconnected load and apply the concept and technology of the Smart Grid system, which will not overestimate the value of disconnected load and reduce losses in production technology by 7–9 %.

Keywords: oilfield consumers, priority of outages, shortage of active power, technical condition index (TCI), reliability category, final integral indicator.

In the construction industry, work is constantly underway to construct buildings designed for various purposes in the residential and industrial sectors, trade, transport, etc. The basis of any construction project is the foundation, which can be of different types, in particular, pile. The piles provide excellent stability on a variety of soils. The pile driver construction machine, which has various drive systems, is widely used for driving piles. Each type of pile driver construction machine is designed for certain technical and economic conditions and has its own disadvantages and advantages. The article examines the possibility of using a non-standard drive control system for the pile driver construction machine and evaluates the feasibility of its use. Purpose of the research: calculation and design of a cylindrical linear valve motor installed on the mast of the pile driver construction machine, which is proposed to be used as an electric drive for a jackhammer for driving piles into the ground. Methods: based on the results of a comparative analysis of all types of pile driver construction machines, a cylindrical linear valve motor is calculated using the MathCAD environment, as well as a modernized calculation to ensure the required traction force. Results: the calculation of the required traction force of a cylindrical linear valve motor with permanent magnets has been carried out, and a sketch of the electric motor located on the mast of the pile driver construction machine is presented. An electric motor control system has been developed. Practical significance: the proposed electric drive system completely eliminates all the disadvantages of standard pile driver construction machines. The traction force required to lift the hammer is achieved by reducing the weight of the hammer and its metal content. This eliminates the need for mechanisms that play a key role in the operation of standard construction machines. The control system for the electric drive of the machine and the algorithm for its normal operation when driving piles and in emergency mode are presented.

Keywords: cylindrical linear valve motor, drive system, copter, traction force, design.
