In this work using the example of a radio center the issue of organizing an electrical system with distributed generation of a consumer with a sharply variable nature of the load is considered. The creation of electrical complexes based on distributed energy generation is a promising direction in the development of energy. One of the problems that can be solved using distributed generation is the smoothing the power profile of the consumer. The purpose of the research work is to study the features of the organization of an electrical system with distributed generation of a radio center with a sharply variable nature of the load. When constructing structural diagrams of the power supply system of the radio center, the fundamentals of power supply of industrial enterprises are used. Recommendations on the technical parameters of power plants are integrated based on the results of research in the field of distributed power generation and related regulatory documents and radio communication systems. Based on the results of the research work, the technical characteristics of power plants are noted, which should be paid attention to when designing an electrical system with distributed generation of a radio center. Variants of the structural diagram of the electrical system with distributed generation of the radio center and the corresponding power distribution schemes are proposed.

The physical properties of nanocrystalline systems of cadmium and zinc selenides have been studied experimentally and theoretically. The effect of temperature and various gaseous media on the specific conductivity of films of cadmium and zinc selenides has been experimentally studied. The values of the Fermi energy, the concentration of donor charge carriers in the conduction band, the activation energy of donors, and the temperature coefficient of resistance are theoretically calculated. It is shown that the calculated values correlate with the experimental ones, which will make it possible to predict the stability of the operation of semiconductor devices.

The aim of the study is to develop methods for forming a control channel for sorting roundwood based on an asynchronous three-phase motor with a phase rotor. In the study, a simulation modeling method is used to verify the operability of the developed implementation of the control channel, and to evaluate the errors in the functioning of the control system. Based on the results obtained, it can be concluded that the proposed method of forming a control channel for controlling discrete sorting devices can be used.

Measurement and control of the intensity levels of inhomogeneous electric fields with high accuracy is quite a difficult task. The solution to this problem is connected both with the development of new sensors and methods for measuring the electric field strength. The creation of new high-precision electrical induction sensors has exhausted its capabilities at the current level of technology and technology. Therefore, new ideas are needed for solving the problems of high-precision measurement of the electric field strength. One of these ways is the development of new measurement methods. Existing measurement methods characterized by the complexity of the measurement processes, suitability in some cases, and unsuitability in others, do not provide the desired metrological characteristics. Therefore, the work related to the development of methods for measuring the intensity of inhomogeneous electric fields does not stand still, and is relevant. The aim of the study is to create a new method for measuring the strength of electric fields using known sensors, which makes it possible to significantly reduce the error in measuring inhomogeneous electric fields. The idea of constructing a new measurement method is formed. The idea of the method is that in the presence of two physical quantities measured with different sign values of the error, the average value of the physical quantity will always be closer to the true value. Based on this, a new method for measuring the intensity of inhomogeneous electric fields is proposed, associated only with the original measurement process. The measurement method id named «Average value method» (MSZ). The estimation of the error of this method shows a decrease in the measurement error to +5 % with the full spatial measurement range 0a1. Using the «Average value method» it is possible to achieve a significant increase in the accuracy of measuring the strength of inhomogeneous electric fields in a wide spatial range of measurements in comparison with known methods

The issues of introduction of electrical digital substations in the Russian Federation are considered. An existing criteria analysis for assessing the modern relay protection devices efficiency is carried out and an assessment of their sufficiency is made. A mathematical model development of the digital substations relay protection complexes operation has been developed using the queuing theory, the graphs theory and Markov chains. The failure-free operation probability calculated value of the relay protection complexes corresponds to the long-term analysis data. This indicates that the mathematical model is correct. The proposed mathematical model makes it possible to take into account the impact of the maintenance quality on the digital substation relay protection complexes efficiency.

Two main factors are considered that determining the friction between non-lubricated surfaces of an elastomer and a solid base during their relative motion. The first one is adhesion in the areas of real (actual) catalysis and the second factor is the deformation component, which is due to the delay of recovery of the elastomer after the irregularity is introduced and it is called the hysteresis component of friction. One of the main problems of increasing the resource of pneumatic dampers is minimizing the wear of the covering layer of the rubber-cord casing (RCC). The wear of the RCC is due to the fact that sliding friction occurs in the process of contact between the metal surface and the surface of the RCC, as a result of which the cover layer of the RCC (in some cases with the first cord layer) wears out, depending on the chemical composition of the rubber and the features of the operation of the pneumatic shock absorber. In order to minimize the wear of rubber, it is proposed to change the design of the pneumatic damper so that rolling friction dominates in the contact between the surfaces of rubber and metal

The article is devoted to the study of ecosystem controlling and divided into three structural sections. The study is of an overview nature, aimed at popularizing ecosystem approaches in the domestic industry. The main methods of scientific research are systematization and analysis. The introduction provides evidence of the need to search for new solutions to optimize and improve modern domestic industry. The first section analyzes definitions related to the ecosystem. It is considered from the classical (biological) point of view and from the point of view of application in industry. The evidence base of the justification of this approach is given. The second section is devoted to the problems present in industrial ecosystems. The list of the most significant features caused by staff misunderstanding of new approaches is made and the unjustifiability of outdated methods of production organization used everywhere is argued. At the same time, the section focuses on the importance of the manager who is responsible for the functioning of departments and specifies the characteristics required for him. The third section shows the importance of ecosystem controlling as a way to solve the described problems. As evidence, it is divided into two obvious components — technical and human. The direction of the Internet of Things as an integral part of the industrial ecosystem is noted. As a solution to the human component, an example of implementation for little-changing systems is given and recommendations are given for systems of a different nature. In conclusion, the supporting facts of the correctness of the conclusions are given.

In this part of the article, the discussion of the construction of jet-drop optical measuring systems (JDOMS) for monitoring the electric field strength continues. The possibilities of increasing the resolution are considered. A variant of the interference JDOMS using triangulation stroboscopic measurements of displacements of charged moving droplets using a pulsed acousto-optic interferometer of transverse displacements of a laser beam is presented. The possibilities of increasing the charge/mass ratio of charged droplets, the features of using liquid metals and their two- and three-component alloys as liquids, the use of inhomogeneous droplets in the form of hollow, hollow microspheres similar to soap bubbles and/or based on a porous (dispersed) material are discussed.
