The invention discloses a quasi-bilateral power supply traction power supply system, which comprises a first traction transformer, a first in-phase power supply converter device, a second traction transformer, a second in-phase power supply converter device, a section post, a controller, a first substation and a second substation, wherein the first traction transformer is arranged in the first substation and used for receiving external electric energy and carrying out single-phase voltage output to a traction network; the first in-phase power supply converter device is used for outputting single-phase voltage to the traction network under the control of the controller, and the phase of the first in-phase power supply converter device is the same as that of output voltage of the first traction transformer; the second traction transformer is arranged in the second substation and used for receiving external electric energy and outputting single-phase voltage to the traction network; the second in-phase power supply converter device is used for outputting single-phase voltage to the traction network under the control of the controller, and the phase of the second in-phase power supplyconverter device is the same as that of output voltage of the second traction transformer; and each of the first substation and the second substation is provided with only one transition area. By applying the scheme provided by the invention, various problems caused by electricity phase splitting of the substation are avoided. The invention further provides a train power supply network which has corresponding effects.
本申请公开了一种准双边供电的牵引供电系统,包括:设置在第一变电所中的第一牵引变压器,用于接收外部电能并向牵引网进行单相的电压输出;第一同相供电变流装置,用于在控制器的控制下向牵引网进行单相的电压输出且相位与第一牵引变压器的输出电压相位相同;设置在第二变电所中的第二牵引变压器,用于接收外部电能并向牵引网进行单相的电压输出;第二同相供电变流装置,用于在控制器的控制下向牵引网进行单相的电压输出且相位与第二牵引变压器的输出电压相位相同;分区所;控制器;第一变电所及第二变电所均仅具有一个过渡区。应用本申请的方案,避免了变电所的电分相所带来的诸多问题。本申请还提供了一种列车供电网络,具有相应效果。
