PAPER TITLE SYSTEM MODEL FOR TESTING AUXILIARY ELECTRIC MACHINES OF TRACTIONAL ROLLING STOCK

Abstract

Purpose. The development and implementation of energy-efficient test schemes for auxiliary electrical machines of rolling stock requires mathematical modeling in order to determine the most rational scheme from the point of view of the quality of the tests performed, as well as to minimize energy costs for conducting the tests themselves. Methodology. The methodological basis of the research is the analytical research methods based on the compilation of the calculation system of differential equations by solving which it is possible to determine the parameters of the mutual load scheme. Findings. Given the fact that the mutual load system is complex enough to be solved by the system, in the work, the system was decomposed into simpler schemes for replacing the electrical and mechanical parts. A system of differential equations was created on the basis of substitution schemes, which made it possible to create a model of a mutual load system with three input and three output parameters. The developed model can be easily implemented in specialized software environments (for example, SIMULINK) using standard built-in blocks. Originality. A rational scheme for testing auxiliary machines by the mutual load method is proposed, with coverage of losses from one source of electrical power. Practical value. The implementation of the obtained results by enterprises for the repair of auxiliary rolling stock machines will allow to reduce the material costs of carrying out repairs while maintaining the quality of the conducted tests.
