Abstract

The present invention belongs to the field of direct-current traction power supply systems. Disclosed is a control architecture for a flexible direct-current traction power supply system based on energy routers. The flexible direct-current traction power supply system comprises a plurality of traction substations, and external power sources connected to the plurality of traction substations, wherein locomotives are connected to the traction substations by means of a catenary system, each traction substation comprises a plurality of energy routers, and each energy router comprises at least three ports, a first port being connected to the external power source by means of a traction substation alternating-current bus, a second port being connected to the catenary system by means of a traction bus, and the other ports being connected to one or more of photovoltaics, wind power, energy storage, a direct-current load and an alternating-current load. The solution of the present invention overcomes the defects of existing direct-current traction power supply systems using a diode rectifier unit as a core power supply device and existing direct-current traction power supply systems based on energy routers in the aspect of system structure design, and provides a corresponding collaborative control technical solution.
