Tretiak M. Combined power systems for electric transport of agricultural assignment

The оbject of research: combined power system of autonomous electric vehicles with electrochemical storage and diesel - generator. The purpose of research: improving efficiency of the combined power system for electric transport vehicle of agricultural assignment by setting optimal energy interconnections between elements of the system at hard variable mods and develop new control algorithms of energy flows. Methods of research: theory and methods of differential equations of mathematical physics, the theory of electrical circuits, mathematical modeling based on software products Matlab - Simulink. Theoretical and practical results and innovations: improved method for calculating the efficiency of the combined power system, which allowed us to determine a method of controlling the energy flows from the two power sources to ensure the highest possible efficiency. Developed a method for calculating the energy component parameters of vehicle for agricultural purposes, which takes into account the hard variable mods tillage operations. Proposed in the method of calculating the parameters of a diesel generator booster installation allows the design phase to adjust the characteristics of vehicles with a combined power system. A subject degree of introduction: use the development of modern transmission and promising agricultural tractors in "HTZ". Effectiveness of implantation: results of the thesis introduced allow: to determine the capacity of the energy storage device, to design highly efficient power tractors, develop modern electric transmission control system. Sphere of use: vehicles for agricultural purposes.
