The invention discloses an electrified railroad homo-phase traction power supply system. A traction transformer (SS1) of a traction substation is a three-phase-two-phase transformer; three phases (A, B and C) of the primary side of the traction transformer (SS1) are connected with a public power grid; a voltage reduction transformer (G), a first single-phase current transformer (M1), a direct-current capacitor (C) and a second single-phase current transformer (M2) are connected between an alpha output phase and a beta output phase of the secondary side in turn; the alpha phase supplies power to a locomotive (L), and the output voltage of the alpha phase is 27.5kV; and the output voltage of the beta phase is between 600 and 2,000V. The system can implement two-arm homo-phase power supply of the railroad traction substation without split phase, reduces the split phase link, is favorable for high-speed, stable and safe operation of the railroad, and has the advantages of simple structure, ...
