The invention discloses a networked traction power supply system based on integration of three networks. The networked traction power supply system comprises a traction substation in wired communication with an optical fiber network and a train capable of being in wireless communication with the traction substation. After the optical fiber network processes the received data, internal parts of the traction substations are controlled, the traction substations share load data of the traction substations through the optical fiber network, and the traction substations communicate with trains located on power supply arms on the two sides of the traction substations through a wireless network; an incoming line of a power system in the traction power supply system is connected to the primary side of a substation in the same phase sequence, and the output end of a transformer and the output end of a power flow controller are connected with the direct secondary side output of a traction transformer through a traction network to jointly supply power to the traction network. The system has the advantages that through power supply is achieved through the power flow controller, power supply islands are eliminated, equalizing current and an electromagnetic looped network are not generated, and the power supply capacity and the regenerative braking energy utilization rate are improved. The energy storage device realizes new energy interconnection and improves the environment-friendly level of power utilization of the power supply system.
