Control of electric rolling stock based on instant traction calculations using the system operating modes railway electric supply

The paper considers the issues of managing the interaction of electric rolling stock and the energy infrastructure of railways in the conditions of limitations of the energy infrastructure on the experimental electrified alternating current section of the West Siberian Railway. It is obtained the results of the movement of electric freight locomotives with installed measuring equipment on electric rolling stock and two traction substations of the electrified alternating current section. An instant calculation was made of the degree of influence of electric locomotives on the parameters of the traction power supply system including voltage nodes with other electric locomotives, the degree of mutual influence of electric locomotives; control actions on electric rolling stock were determined to provide the statuses of other trains in real time based on measurements of currents, voltages, power and other parameters under conditions of limited power of the traction power supply system. The proposed approach will make it possible to obtain in real time, based on data on the load of traction substations, voltages in the inter-substation zone, restrictions on train movement at inter-train intervals, maximum speed based on energy conditions in a real situation, coordinating control actions between trains in the inter-substation zone based on priority.
