Модель нормування витрат енергії на тягу електропоїздів

Abstract

The article considers the issues of determining the energy resources consumption for train traction, taking into account the train conditions and features of traction rolling stock. The criteria of optimality of any mathematical model as well as the requirements to it have been established. The physical essence of fuel and electricity consumption rationing at JSC «Ukrzaliznytsia» in general has been presented and considered taking into account the conditions of the work of the locomotive depot and the driver in particular as well. The curves technique of limiting the consumptions rationing range has been analyzed and possible solutions have been presented. Taking into account the Master controller, as an element of control of train driving modes, an example of homogeneous discrete Markov chains of train driving mode selection has been considered. The actual state of electric power consumption rationing has been analysed by the instructors in heat engineering of the motorwaggon depot. The absence of initial norms of electric power consumption from the traction-power passports of electric trains has been found out. Taking into account intensive development of electronic computers and availability of personal computers at the depot a flexible adjustible schedule has been offered, programmable and suitable algorithm for the drivers under operating conditions of analog traction rolling stock. The existing approaches to the calculation of electricity consumption rates for traction of electric rolling stock have been analyzed and compared with the current state of the rationing methodology. The requirements of drivers-instructors in heat engineering (and other personnel for control, processing and adjustment) as well as the availability of electronic and computer equipment at the depot have been considered. Based on the division of expenses for the traction itself, operation of auxiliary machines and heating of electric trains, a mathematical model of establishing the amount of electricity consumption for electric trains traction has been proposed. Relevant conclusions were made at the study on the introduction of mathematical modelling in the expressions that reflect the standards of energy consumption
