FIELD: railway transport power supply systems.
SUBSTANCE: invention relates to power supply systems for railway transport. The method for determining the energy indicators of the traction power supply system consists in determining the voltage on the current collector of the electric rolling stock during traction and electrical calculations, taking into account the operating modes of the electric power storage devices. At the same time, the calculation of the energy indicators of the traction power supply system is carried out according to the data of previously performed traction calculations for various voltages and speeds in the range of established values with a given step of change so that, depending on the voltage level at the pantograph of the electric rolling stock and the speed of movement, the appropriate traction calculation is selected, based on which, at the next step of calculations, the load and voltage on the pantograph are determined, which is used at the next step of calculations to determine the load of the electric rolling stock.
EFFECT: reducing the computational complexity of calculations, taking into account the operation of control devices.
