Abstract

The introduction of distributed power supply systems for the supply of high-speed trains allows for the necessary mode of power and voltage in the traction network. In the design of circuitry systems of distributed type an important task is the choice of the power channel for feeding points of amplification. Today, as such channels, power lines are used for direct and alternating current. Also known are theoretical developments of power channels of another type: with high frequency, a link of direct current and others. The proposed work presents the results of calculations of the AC power line with voltage of 35 kV as an energy channel of a distributed traction power supply system for supplying a 5 MW power gain point. It is shown that in order to provide the necessary energy indices, the use of AC-35 wires is sufficient for normalized power losses and voltages.
