Abstract

For today, Ukraine is discussing the transfer of 6 (10) kV distribution lines to 20 kV, moreover, appropriate decisions are made and designs for the reconstruction of existing lines are being developed. At the same time, there is great uncertainty about the application of the voltage level of 20 kV both in the regulatory field and in technical and economic feasibility, as well as the possibilities of technical implementation and hardware support. The work is devoted to the estimation of energy efficiency of electric networks of longitudinal electric power supply of railway transport at increase of rated voltage of distribution networks. Calculations are given of the distribution of currents, power losses and voltage in the network for rated voltages of 6, 20, 35 kV. The cost of electricity losses in the network for these nominal voltages is estimated.
