Hubskyi: ORCID 0000-0002-0216-7256EN: Abstract. The classical systems of centralized power supply do not allow to provide the necessary conditions for the introduction of high-speed traffic on existing lines. Voltage values both on the buses of the traction substation and in the traction lines have a significant range of oscillations. Having a significant reserve of installed aggregate power at traction substations in Ukraine, there are no means of voltage modes regulation in the traction lines. Existing foreign and Ukrainian means for increasing of the energy efficiency of ОС traction power supply systems require significant capital investments and do not take into account the peculiarities of the organization of high-speed traffic. Therefore, it is ology of distributed power supply with the maximum use of existing infrastructure, taking into account the features of the high-speed trains load.envoltage and power modestraction power supply systemDCdistributed powerpower lossesКІСЕArticle
