The invention discloses a method for acquiring the minimum voltage level of a tractive power supply system in a high-speed railway network. The method comprises the following steps: (1) enabling the tractive power supply system to adopt an up-down parallel AT power supply mode and calculating the voltage loss deltaUj in a traction network; (2) judging the connection mode of a traction transformer in the tractive power supply system and acquiring the voltage loss deltaUTmax of the traction transformer in the tractive power supply system according to the connection mode of the traction transformer in the tractive power supply system, and then calculating the voltage loss deltaUSmax of an electric power system according to the connection mode of the traction transformer in the tractive power supply system; and (3) acquiring the minimum voltage level Umin of the tractive power supply system in the high-speed railway network according to the voltage loss deltaUj in the traction network, the voltage loss deltaUTmax of the traction transformer in the tractive power supply system and the voltage loss deltaUSmax of the electric power system, wherein Umin is equal to 29-deltaUj-deltaUTmax-deltaUS. The method can be used for accurately acquiring the minimum voltage level of the tractive power supply system in the high-speed railway network.
