The invention provides a rail transit traction power supply system. The system comprises: a direct current line laid along a track, and a first traction power supply station and a second traction power supply station which are arranged on the direct current line; a first power converter is arranged in the first traction power supply station, is connected to an external power supply and transmits electric energy of the external power supply to the direct current line; and a traction power supply converter is arranged in the second traction power supply station, is connected to a traction powergrid, and transmits the electric energy transmitted to the direct current line by the first traction power supply station to the traction power grid. According to the method, the dependence of the rail transit traction power supply system on an external power supply is effectively reduced, the power supply stability and the power supply capacity of the rail transit traction power supply system areimproved, and then the operation reliability and the transport capacity of an electric locomotive are improved.
