The article deals with improving the method for determining the energy performance of the train and
the traction power supply system based on the time schedule for a certain railway section. Refinement of calculation for the trains in regenerative braking mode was selected as one of directions of improving this method. Traction calculations are currently carried out under the assumption that the voltage at the pantograph of electric rolling remains constant in all train modes. The above assumption introduces a certain error into calculation of the energy performance of the train and traction power supply system.
In order to increase the calculation accuracy, it is proposed to change the order of calculation and to complete it with check of regenerative braking application conditions. For this purpose, traction calculations are supposed to perform at each step of computing energy performance of the traction power supply system to take account of the voltage level on the current collector. This train regenerative braking mode is used in calculation for provision of appropriate conditions only based on test of the current collector voltage and power balance between substations and traction power supply adjacent areas.
