Shokarov D. Control system of the traction asynchronous electric drive of a contact and accumulator miner electric locomotive

Object of research - electromagnetic and electromechanical processes in the traction electric drive of miner contact and accumulator electric locomotives with IGB transistor inverters and asynchronous engines. A research objective - increase of energy efficiency of electrotechnical complexes by use of synergetic effect in structure of the traction asynchronous electric drive, two-system on a diet: a contact network - the traction battery for creation new to domestic mines and a safe contact and accumulator electric locomotive in operation. Research methods: methods of the theory of automatic control - for the structural analysis and creation of structure of system of automatic control of the multi-engine electric drive; methods of mathematical modeling - for creation of mathematical model of the two-engine drive; the harmonious analysis - for research of harmonious structure of curve tension and currents in the asynchronous electric drive; mathematical modeling on the computer and pilot studies - for verification of theoretical provisions and scientific results. Theoretical results: for the first time it is offered the traction asynchronous electric drive on the basis of the modernized technological platform of the existing designs and reasonably the law of control of the asynchronous electric drive; it is for the first time offered and developed multipurpose mathematical model for the analysis of electromagnetic processes in the traction asynchronous electric drive: "The IGBT inverter - traction asynchronous engines of a miner contact and accumulator electric locomotive"; the method of creation of independent inverters in a complex of the traction asynchronous electric drive is improved; expediency of management of invertor bridges of a contour of power supply of traction asynchronous engines of way of direct pulse-width modulation of tension is for the first time proved. Practical results: it is offered and passed approbation during the previous researches of an experimental sample of a contact and accumulator electric locomotive in the conditions of the operating iron ore mines structure of the asynchronous frequency and adjustable electric drive; it is offered and is recommended for practical researches a method of calculation of capacity of the battery of a contact and accumulator electric locomotive. Extent of introduction - results of researches are transferred to the specialized enterprises: State Enterprise NPK "Electrovozobuduvannya" (Dnepropetrovsk), JSC "Electrozahyst" (Kharkov). The results of scientific researches are introduced in educational process of the Kremenchug national university Mikhailo Ostrogradsky memorial. The sphere (area) application: electrotechnical complexes of mine electric locomotives.
