Diesel trains with asynchronous traction motors management strategies modeling

In this research, by using the extended motion model of DEL-01 (02) diesel train with asynchronous traction motors the graphs of speed, power consumption, driver’s controller switching position dependences on the traveled distance and the time for different railway hauls profiles and different strategies of the train driving are obtained. The analysis of the graphs results in the conclusion of the feasibility of using the following strategy of train driving: acceleration with short-term presence on the positions 1, 2 and 3 of the driver’s controller and a long-term presence on the economical positions 4, 5 and in particularly 6 with the preferred evasion of positions 7 and 8; coasting; braking. Since the model takes into account not only the dynamics of the train, but also the influence of automatic and frequency control of traction engine electric drive and other factors, this strategy allows to provide a reduction in fuel consumption and the safest mode of movement of diesel trains in terms of electromagnetic compatibility of its systems. It is proposed to use the dependence graphs, obtained by simulation of module on neural networks, able to analyze the current mode of train driving and make recommendations to a train driver to reduce fuel consumption, improve operating conditions and comply with the timetable.
