Özet:

In the article it is analyzed the voltage regulation on bus traction substations to extend the range of electric recovery in limited traction electricity that allow to reduce the number of failures of regenerative braking and power consumption for traction. On the basis of modeling of power distribution stationary regimes in the traction power supply with energy recovery, the dependence of the recovery zone from removing trains, their currents and voltages on the bus traction substations is determined. The regularities of formation of circulating currents in the traction power supply system with energy recovery are determined. The level of energy loss in traction network from traction substation voltage control that requires a comprehensive assessment of energy-saving recovery use is determined.
