Energy efficiency matching of electric traction network with double and single-way circuits

The challenge of power loss benchmark in electric traction network with parallel and traditional separated operating conditions of traction substation feeders is issued in terms of energy efficiency of urban electric transport. The traction network area of Novosibirsk tram with high power supply imbalance was chosen and experimental measurements were made with operating conditions being reviewed. The calculation data results based on statistic processing showed the loss decrease in contact network and the increase in feeders. The changes proved to be critical ones and this demonstrates the significance of potential effects when converting traction network areas into parallel feeder operation providing symmetric current distribution in feeder area.
