Evaluation of additional power losses in the power supply system of high-speed traffic

摘要

The introduction of high-speed and heavy traffic on the electrified railway DC highlighted some contradictions in the existing excess capacity of traction substations and traction networks do not provide the necessary level of voltage and power density. Because there are existing ways of strengthening is not effective enough and not received wide implementation in Ukraine, we offer a transition to the new circuitry traction network – distributed type. The article highlights one aspect of this transition was to evaluate and compare Liny analysis of power losses to compare the centralized and the distributed type, taking into account losses from higher harmonics.
