“…The specified diesel locomotive refers to a land-based wheeled vehicle with a power energy plant [3] -this is diesel 1A-5D49 of the third version, which is characterized by high efficiency with specific fuel consumption at rated power mode (2206 kW) equal to 208 g/kW-h and hourly fuel consumption of idle mode -14 kg/h. An analysis of scientific research by domestic scientists [4][5][6][7][8][9][10][11] and scientists from far abroad [12][13][14][15][16][17][18][19][20][21][22][23][24], aimed at studying the efficiency of various types of locomotives, their systems, units and apparatus in the conditions of operational activity of railways and of railway transportation of goods the organization, indicates that no the a sufficient degree of study of issues related to the justification of the kinematic parameters of the movement of freight trains and the parameters of the energy efficiency of locomotives on virtual and real sections of railways of varying complexity, including of Uzbek ones.…”

A program algorithm and a method for producing (performing) traction calculations are proposed, based on geometric constructions of changes in the speed and time of train movement along the track, relying on the specific resultant forces of the train in the travel track of rolling stock. Calculations of the kinematic parameters of the movement of a freight train on a virtual hilly section of the railway were carried out using a graphic-analytical method when moving with stops and without stops at the intermediate and final stations. The values of the energy efficiency indicators of UzTE16M3 diesel locomotives when driving a freight train with a minimum train weight in quantitative and monetary terms are substantiated. The numerical results of the research are obtained in the form of tabular data, which specialists of the locomotive complex can use when analyzing and assessing the efficiency of the transportation work of UzTE16M3 diesel locomotives under real operating conditions.

“…Research shows that increasing voltage is an effective way to reduce electrical losses in networks. Therefore, upgrading power transmission lines and increasing voltage are important measures to improve the efficiency of electric networks and reduce electricity losses [7]. One of the effective ways to reduce electrical losses in electrical networks is to increase the voltage in distribution networks.…”

The article considers the basis of scientific research in the field of electric power industry the issues of transition to 20 kV voltage in the distribution power grids of Uzbekistan. The main advantages of this method are analysed, as well as the factors affecting power and energy losses in electrical systems and networks. The paper presents a schematic diagram of an electric network section, on which a comparative calculation and analysis of voltage, energy and power losses in 6/10/20 kV networks is carried out. Special attention is paid to the peculiarities of calculation of these parameters, as well as the basic expressions for their calculation and the resulting graphical relationships. From the analysis it can be concluded that it is reasonable to use 20 kV voltage in distribution networks. It allows to reduce power and energy losses, which is an important factor in the efficient operation of electric power systems, to increase line capacity and service range. However, when selecting the optimal voltage for certain conditions, it is necessary to take into account a number of factors, such as the length of transmission lines, the type of wires and transformers used, and the load level of the network.
