Parameters of the protective coatings providing safety and electromagnetic durability of electronics of the smart grids from the electromagnetic disturbances of natural and artificial origin have been proposed. Considered protective coatings consist of magnetic and dielectric layers with losses. It permits to avoid reflections from the layers and to reduce levels of the electromagnetic field intensities of refracted waves due to their attenuation during propagation from layer to layer with increasing active losses. Parameters of such layers were determined with the help of the mathematical modeling of the electromagnetic processes. Made comparison with the analytical solutions of the results of numeric simulations proves their accuracy not exceeding 2 %. With the help of proposed coatings, refraction and reflection of the electromagnetic waves from conductive elements can be effectively reduced - by an order and more.

The circular economy (or closed-loop economy) model is an alternative to the traditional, linear manufacturing economy model. Its main task is to organize a closed cycle of production and consumption of products and services and recycling and/or reuse of by-products and waste, which is the undoubted advantage of the circular economy model over the linear one. For its part, this requires the creation of a specialized system of information and communication relations between all participants and, above all, with end users of products and services. In this paper, the solution of this problem is proposed to be carried out on a technological platform by a synergistic combination of methods of service-dominant logic and product-service systems based on information and communication technologies. Closed cycles of production and consumption of energy-intensive products, equipment and materials should be organized, covering almost all links in the transformation of energy resources - from their production to consumption. The central place in this should be occupied by the Internet of Things - an open technological platform where the flows and resources of the system participants (material, energy, financial and economic, information, etc.) will intersect. As a structural form of implementation of the platform under consideration, a vertically integrated form of controlling an inextricable chain of processes for the production and consumption of products and services is proposed. As a fundamental principle for the application of such control, the possibility for system participants to choose the optimal degree of their organizational and functional independence within the limits of intra-system restrictions, regulated by higher-lying subjects (objects) of the system, is determined.

The system of automatic voltage stabilization of a three-phase magnetoelectric generator with magnetic flux shunting in the conditions of robot speed change is considered in the work. The magnetoelectric generator is intended for use in autonomous installations of small generation of the electric power. The generator is created on the basis of the serial asynchronous electric motor that provides economy of production of a power source. The voltage of the generator is controlled by changing the magnetic flux of the working area using the current of the stationary winding of the shunt, powered by direct current. A mathematical model of a magnetoelectric generator with magnetic flux shunting in the rotor coordinate system is presented. Algorithms for shunt current and generator voltage control based on the method of inverse dynamics problems in combination with minimization of local functionalities of instantaneous energy values were synthesized, which provided simple synthesis, dynamic system decomposition and low sensitivity to parameter changes. The operating characteristics of the experimental sample of the magnetoelectric generator are presented, which show the possibility of voltage control. The quality of generator voltage control when changing the rotor speed within ± 15% of the nominal value was studied. The developed control system provides astatic voltage regulation.

The given method of optimizing the modes of main electric networks allows obtaining a universal approach for solving such tasks as minimizing the total losses of active power and compensating excess flows of reactive power. The methodology for selecting the parameters of compensating devices of controlled ultra-high voltage power transmissions with intermediate systems to ensure the balance of reactive power has been substantiated. An analytical solution to the problem of selecting the parameters of the compensating ultra-high voltage power transmission line with one intermediate system was obtained. An approach to solving the problem of optimization of the main electrical network is presented, taking into account the provision of reactive power balance. The objective function and its optimization criteria are described. The method of optimizing the mode of the electrical network according to voltage and reactive power was developed with an assessment of the effectiveness of the use of controlled compensating compensation devices, and the possibility of applying this approach was revealed. Recommendations are given on the use of reactive power compensators to improve the reliability and quality of power supply. The technique has been developed for evaluating the efficiency of controlled nodes based on optimizing the mode of electrical networks containing such nodes. In the work, two problems are solved when choosing installation sites and values of parameters of compensating devices: balancing reactive power and optimizing the operating modes of the main electrical network according to the criterion of minimum active power losses. The most efficient hardware based on static devices of the FACTS technological platform is proposed.

The scope of shown problems in the paper is devoted to energy and environmental assessment of industrial gas burning installations equipped with jet-niche combustion technology (JNT). The basic principles underlying this technology include: rational distribution of fuel in the oxidant stream; stable adjustable structure of fuel, oxidant and combustion products; self-regulation of the composition of the fuel mixture in the zone of torch stabilization when changing the load of the unit. As of today, a large number of industrial gas-burning equipment has been modernized by jet-niche technology, including: boilers, furnaces, dryers, metallurgical facilities, etc. The results of industrial implementation of the burning technology allowed to accumulate a significant amount of technical information and provided an opportunity for preliminary environmental assessment during the modernization of gas-burning unit (GBU). As practice shows, at the present stage the main direction of improving the technology is to improve its environmental performance. The influence of the main mode and technical parameters of GBU on its emission indicators is established in the paper. Possibilities for reduction of nitrogen oxides by primary technological methods have been identified, the simplest and most effective of which is the introduction of recirculation gases into the furnace space. The data obtained from the results of the analysis emission indicators of the modernized GBU with a capacity of 0.5-60 MW help estimate the emission rate low and medium power boilers depending on the main influencing factors, namely the unit size, excess air ratio and boiler load. The effect of the introduction of recirculation gases into the furnace space on the level of nitrogen oxides concentration is also taken into account. The efficiency of application of the scheme of recirculation gases introduction into the primary air flow in comparison with combustion technologies based on vortex burners is shown. According to the results of the industrial experiment, the energy efficiency of the proposed measures was established on the example of the dependences of efficiency on the load of boilers PTVM-50 and KVGM-20.

Wind power plants with nominal power of 0.5-5.5 MW, as a rule, are designed at voltages of 10–35 kV. In addition to technical conditions and restrictions, a number of economic criteria must be taken into account when designing wind power electrical collector networks. For green energy facilities, due to the high green tariff, the energy losses in the electrical collector networks can significantly affect the payback period. Therefore, during the design it is necessary to choose such cross-sections of cable core that will ensure the minimum cost for the entire period of building and operation of the wind power plant. An analytical dependence is obtained, which allows to calculate the economically justified current density for the cores cross-section of such cables for a nominal voltages of 10, 20 and 35 kV for different periods of maximum generation of wind power plants. It is established that changes in the payback period in the range of ±1 year from the estimated cross-section of cable core will not change, because the scale of cores cross-sections is discrete. The values of economic current densities for different periods of maximum generation are given in the article. They allow to choose rational cross-section of cable core during the design of wind power electrical collector networks.
