Solid Biofuel Production Perspectives in Ukraine
Authors: Panchuk М. V. , Semianyk І. М. , Mandryk I. O, 
Published: March 2020

The reserves of fossil fuel resources in Ukraine are limited, that is why the usage of solid biofuel from renewable raw materials is one of the most important factors of state energy policy directed at the preservation of traditional fuel and energy resources and improvement of the environment condition. The analysis of biological resources is made in this paper, and it is determined that Ukraine has a sufficient potential which is available for energy production and constitutes around 29 million tons of equivalent fuel. Energy crops are an important resource therewith. A potential yield of solid biofuel from perennial energy crops can constitute approximately 35.8 million tons per year. It is shown that raw biomass has a number of disadvantages: low energy density, unstable granulometry, wide spread of moisture content, and low bulk density which are the main problems for its storage and transportation. In order to increase consumer performance properties of biomass, the granulation process is suggested to be used. The implementation of granulation process will allow to eliminate the shortcomings of biological raw material and to transform it into a high-efficiency fuel. One of the most important conditions of effective and profitable functioning of granulated biomass production is the availability and regular supply of raw materials. Therewith, for Ukraine's conditions it is worthwhile to use sets of high-power equipment for its operation both in the places with high concentration of raw materials and small mobile units which can work in stationary conditions and move to the places with sufficient amount of raw materials decreasing the costs of biomass transportation to minimum. At the same time, there is a need in developing new homeland elaborations, both complex process lines and individual equipment units for different capacities. The paper determines the main directions of using granulation products among which are: combustion in pellet boilers, common combustion with coal, and gasification of granulated biomass for obtaining motor oils. It is mentioned that the application of granulation technologies solves not only the energy problems but also a set of other problems: ecological, agricultural, forestry and social ones.
Improving the efficiency of oilfield electric power distribution

Published: March 2020

The issues of increasing the efficiency of electricity transmission to consumers with different nature of their load are considered. The dependence of the efficiency of the electric network of the oil field, consisting of a power line and a step-down transformer, on the total load power at various ratios between the active and reactive components of the power is analyzed, and the conditions under which the maximum transmission efficiency can be ensured are determined. It is shown by examples that the power transmission efficiency depends not only on the active load, but also largely on its reactive load. In the presence of a constant reactive load and an increase in active load, the total power increases and the power transmission efficiency decreases. In the low-load mode, the schedule for changing the power transmission efficiency approaches a parabolic form, since the influence of the active load on the amount of active power loss decreases, and their value will mainly depend on reactive load, which remains unchanged. The efficiency reaches its maximum value provided that the active and reactive components of the power are equal. In the case of a different ratio between them, the efficiency decreases. With a simultaneous increase in active and reactive loads and a constant value of the power factor, the power transmission efficiency is significantly reduced due to an increase in losses. With a constant active load and an increase in reactive load, efficiency of power transmission decreases, since with an increase in reactive load, losses of active power increase, while the active power remains unchanged. The second condition, under which the line efficiency will be maximum, is full compensation of reactive power. Therefore, in order to increase the efficiency of power transmission, it is necessary to compensate for the reactive load, which can reduce the loss of electricity and the cost of its payment and improve the quality of electricity. Other methods are also proposed to increase the efficiency of power transmission by regulating the voltage level in the power center, reducing the equivalent resistance of the line wires, optimizing the loading of the transformers of the step-down substations and ensuring the economic modes of their operation.

This article considers usage of blue-green algae as biomaterials for creation of motor biofuels. Proliferation of blue-green algae leads to water rotting, destruction of aquatic ecosystems and destruction of rivers and lakes that is why clearing of water bodies from blue-green algae is an urgent task. The object of the study is effect of blended biodiesel fuels from blue-green algae on the environmental and energy performances for the diesel engine. The purpose of the work is experimental study of changes of power and ecological characteristics of automobile diesel engines using petroleum diesel and their mixtures with biofuels derived from blue-green algae. Methods of research are experimental, laboratory ones. Laboratory researches were carried out on an experimental installation based on the serial diesel engine D21A1. As a result of performed experimental researches dependences of changing of the effective engine power on the use of diesel fuel and a mixture of diesel fuel with the received bioactive supplements based on methyl esters of the lipid fraction of blue-green algae Chroococcfles in the amount of 5, 10 and 20 % were established. It has been experimentally established that the effective power of an engine using a mixture of diesel fuel with the derived bioactive compounds based on methyl esters of the lipid fraction of blue-green algae Chroococcfles in the amount of 5, 10 and 20 % will decrease by an average of 0,9, 1,8 and 3,5 %. It has been experimentally determined that the content of carbon monoxide in the use of a mixture of diesel fuel with the derived bioactive compounds based on methyl esters of the lipid fraction of blue-green algae Chroococcfles in the amount of 5, 10 and 20 % will decrease by an average of 6,5, 13,9 and 28,7 %. The obtained results allow to optimize the choice of fuels for power systems of internal combustion engines and to reduce emissions of harmful substances in exhaust gases of automobile diesel engines.
Regularities of Control of Mechanized Pulse-Arc Welding Process for Ensuring its Stability

Published: March 2020

Mechanized arc welding in protective gases with short circuits (s.c.) is performed at moderate values of the welding current (up to 180 ... 220 A) and at the relatively low voltage (18 ... 24 V) on the arc. The main disadvantage of the process is spattering when melting an electrode metal and when transferring it to a weld bath. The elimination of disadvantages is possible through the implementation of a controlled transfer of molten electrode metal to a welding bath - due to the pulsed nature of arc burning. At pulse-arc welding (PAW), one of the main methods of increasing the efficiency of the process is to limit the maximum value of the short-circuit current Imax s.c. by increasing the inductive resistance L in the arc-welding circuit. Proceeding from the features of mechanized arc welding, the purpose of the research is to specify the influence of the velocity of the growth of the welding current vс during the s.c. on the arc stability. The implementation of experimental work presupposes surfacing on a plate with the programming of the operating mode of the inverter at different values (9, 12, 15, 18, 21, 24, 27, 30) with the frequency f = 25 Hz and a pulse ratio C = 2. While analyzing oscillograms of welding current and processing their records, it was established that a decrease of the velocity of the welding current growth leads to a significant limitation of the maximum value of the short-circuit current. The statistical processing of the momentary values of the welding current shows that the increase in the velocity of current growth vс starting with vс = 1.23 kA / s to vс = 50 kA / s makes the average short-circuit duration 10 times shorter. At the same time, the average frequency of short circuits grows more than twice. The increase of vс leads to the destabilization of the pulse process and this is reflected in the 30-times increase of the average frequency of arc break. The increase of the energy indexes of the PAW to the Iav. = 220 ... 225 A, Uav. = 24.5 ... 25.9 V, Q ≈ 7.9 ... 8.0 kJ / cm led to the changes in the parameters which characterize the process of pulsed welding with short circuits. There is a sharp decrease in the average frequency of short circuits (2 ... 3 times as rarely) and the average duration of s.c. (twice shorter).
THE MOBILE SYSTEM REDUCTION FOR THE VIBRATION CONTROL IMPLEMENTATION
Authors: Lopatin V. V. 
Published: March 2020

Since the mining and oil and gas industries play a decisive role in the Ukrainian economy, the adequacy and proper assessment of the accuracy of the monitoring is of great national importance. A mathematical model for the measurement of MSCs is constructed, which determines the sequence of mathematical operations that must be performed to obtain the quantitative characteristics of the objects of control. If there is a function that is a solution and that describes the object of the MSC, then it is a reduction to the ideal MSC. The solution of the problem of reduction (synthesis) MSC is realized by the choice of design and is provided with such a connection between the signals at its input and output MSC, which leads to the best results. This formulation of the problem of reducing the MSC has several disadvantages. The MSC measurement result is always influenced by a number of minor factors. Their effect leads to the fact that the measured value of a certain value is different from the value predicted by the model of measurement of the ISC on the noise (experiment error), which is random. The noise level of MSCs has a significant effect on the result of mathematical processing, and the less the noise, the better the result of the reduction of MSCs. Previously, the task of instrumentation was to create an MSC that provides the least distortion of the measurement results, while using mathematical methods to reduce instrumentation the task of reducing instrumentation noise is MSC. The given solution is realized by the choice of design and is provided with such a connection between the input and output signals, which leads to a decrease in the level of random noise MSC. The description of MSC enhancement has the instability of the solution of the equation with respect to the initial data errors, which is a property of almost all integral equations and does not depend on the method of their solution. The proposed mathematical method of reduction of the mobile control system (MSC) as one of the variants of regularization of the incorrectly set problem arose and was further developed under the influence of the ideas of academician AN Tikhonov and Professor Yu.P. Pytiev . The author suggests taking a different look at the control tasks and the accuracy of assessing the accuracy of MCSs by reducing the level of random noise. The author proposed the implementation of the MCS by choosing a design and providing such a connection between the signal at its input and output, which leads to the best results in solving reduction problems. The author proposed an adaptable model of MCSs using modern ideas and mathematical methods.
