Analysis Of Current Approaches to Modernizing the Electric Power Scheme of Diesel Generator Transport

The work is devoted to the analysis of modern approaches to modernisation of the scheme of power supply of diesel-generator transport and on this basis to the description of the optimal design of such a system. The aim of the work is to analyse modern approaches to modernisation of the scheme of power supply of diesel-generator transport and to develop an energy-efficient structure of such a system. The object of the study is the design of the traction power transmission of a diesel train. The subject of the study is the control system of traction power transmission of diesel trains. The above task of designing an upgraded automatic control system is the main part of the overall task of improving the efficiency of traction power transmission of a diesel train. The paper shows that the synthesized automatic control system should be optimized according to certain principles. In particular, the parametric principle is taken into account, according to which with the chosen structure of the control system and the known functional influences on the traction power transmission such parameters are defined, at which the given quality indicators of transients (indicators of traction inverter operation) are satisfied; the structural principle, according to which the system is designed so that it contains the minimum necessary number of elements, easily physically realized for full operation, is taken into account; functional principle is taken into account, according to which the control laws, and according to them the structure and numerical values of the parameters of the control system are determined. As a result, an upgraded control system of the diesel train traction axle on the basis of subordinate control systems without a speed sensor is developed and substantiated, which allows the movement of a diesel train with a given torque or speed, as well as provides the ability to move the diesel train when the general system fails. control of movement.
