Mathematical model of the controlled distributed DC power supply system

摘要

The article contains issues of performing the calculations for a distributed DC traction power supply system. The mathematical model of such system provides a number of boost points on intersubstation zone with the possibility of regulating their output power in real time. During the modeling was taken into account the influence of adjacent feeder zones, the redistribution of power flows due to the parallel operation of traction substations and boost points, as well as the basic concept of distributed power supply:? increasing the phenomenon effect of equalizing currents due to a larger number of sources with different voltages on the buses. The possibility of applying a direct calculation of electrical quantities makes it possible significantly simplify further optimization calculations of the operation modes of traction power supply systems.
