When modeling the traction power supply systems, reflecting the processes of interaction of electric traction power supply and mobile electrical loads (electric and electric) is one of the elements of movement imitation organization trains in space. The effect of moving trains in simulations (MI) in MatLab on schedule at the analyzed site traffic necessitates sequential switching models of electric rolling stock (EPS) to the traction network, so that its effect is realized by moving the site. However, in this case, there really is not the processes taking place in reality. This is due to the realization of the simulation method of discrete movements, characterized in that the CSE, one located on a cell - the traction network model at one time, thereafter jumps to another. While EPS previous cell is switched off and switched on the next cell. Thus there does not exist in reality switching processes that distort the results of the studies. Methods to reduce the negative consequences of such distortions are addressed in this article.

The paper is devoted to the evaluation of the possibility of effective use of recuperation as a key factor for the traction selection on a prospective railroad in the Russian Far East. The planned line will carry coal and general cargoes, shipping to Sea of Okhotsk ports and overseas. The construction of a new railroad will push development in the north of the Khabarovsk Territory and the northeast of the Amur Region. Due to the line will have a long descent to the seacoast, the main idea is to use the potential energy to generate electricity that covers power needed for oncoming trains going uphill. Performed traction-energy calculations allowed determining the available speed and energy consumption for uphill trains. Shown the ability of power self-sufficient train operations that provided under the condition of ensuring efficient energy exchange between electric locomotives located on the common feeding zone, which is possible only when freight trains operate on a fixed schedule. Given volumes of recuperated energy considered in the research cannot be stored onboard at autonomous locomotives using the existing level of technology, which confirms the need for electrification. The implementation of electric locomotives with an asynchronous traction drive and energy-efficient four-quadrant traction converters can provide an increase in the level of regenerative energy use compared to electric locomotives with zone-phase voltage regulation on traction motors. The proposed solution can significantly reduce the carbon footprint of railroad transportation on the line in question. The possibility of effective use of recuperative energy can use as a key selection factor for the type of traction on prospective railway lines.
