The invention provides a double-current system power supply structure, a control method and a control system for an electrified railway section post. The structure comprises a first traction substation, a second traction substation, a first alternating current bus, a second alternating current bus, a direct current bus, a section post and a measurement and control system, the output end of the power grid substation is connected with the input end of the first traction substation and the input end of the second traction substation. The output end of the first traction substation is connected with the subarea post through a first alternating current bus; the output end of the second traction substation is connected with the subarea post through a second alternating-current bus; the subareas are connected with the measurement and control system; the measurement and control system is connected with the DC bus. According to the method, the network voltage balance at the tail end of the power supply arm of the traction power supply system can be optimized, power can be redistributed by controlling power transmission among the first alternating-current bus, the second alternating-current bus and the direct-current system, and the network voltage balance at the tail end of the power supply arm of the electrified railway is effectively optimized.

    本发明提供了一种电气化铁路分区所双流制供电构造、控制方法及控制系统,构造包括:第一牵引变电所、第二牵引变电所、第一交流母线、第二交流母线、直流母线、分区所、测控系统;电网变电站的输出端分别连接第一牵引变电所的输入端、第二牵引变电所的输入端;第一牵引变电所的输出端通过第一交流母线连接分区所;第二牵引变电所的输出端通过第二交流母线连接分区所;分区所与测控系统连接;测控系统与所述直流母线连接。本发明可以实现对牵引供电系统供电臂末端网压平衡的优化,通过控制在第一交流母线、第二交流母线、直流系统之间的功率传输,可以对功率进行再分配,有效地优化了电气化铁路供电臂末端网压平衡的问题。
