Abstract (English):
The results of computer studies of the modes of traction power supply systems when passing trains weighing 12,000 tons are presented. The parameters are compared with the situation when trains are moving weighing 3,000 tons. It is shown that increasing the mass of trains with the same traffic volume leads to an increase in currents in the traction network, a decrease in voltage at the current collectors, the growth of asymmetry and harmonic distortion in the external power supply system
