Abstract

Most of the Russian Federation territory is located in the zone of long-term exposure to negative ambient temperatures. In this regard, a significant proportion of power consumption in the suburban traffic on the railways of the Russian Federation accounts for the operation of heating and air conditioning systems. Currently, Russian and foreign scientists are developing energy-saving methods and tools to reduce the power consumption for auxiliary needs of electric-multiple units. In this paper, the authors used the method of constructing simulation models in the MATLAB Simulink program in order to create an energy-saving heating and air conditioning system since this method allows you to explore various options for constructing the studied systems with lower financial and labour costs in comparison with the experimental method. In order to verify its adequacy the simulation model includes standard values of electric energy consumption for heating and air conditioning for various sections and operating conditions obtained by the authors earlier during the correlation and regression analysis of data from parameter recorders installed in electric-multiple units. The results of the study showed the adequacy of application of the developed simulation model for organizing the control of power consumption for heating and air conditioning of direct current electric-multiple units.
