The present invention discloses a high-speed railway traction power supply device. The device comprises a traction power supply system, a converter, the photovoltaic power source and a storage battery energy storage device, and the traction power supply system comprises a traction substation, a feeder line, a contact net, an electric locomotive, a track, a return line, a partition pavilion and a switching station. The current transformer, the photovoltaic power supply and the storage battery energy storage device are sequentially connected, the current transformer is arranged between the traction substations, the traction substations and the current transformer are connected through feeder lines, a partition pavilion is further arranged between the traction substations, and a contact net is arranged between the traction substations and the partition pavilion. The traction substation is connected with the switching station, an electric locomotive is arranged on the track, and the track is connected with the traction substation through a return line. The device can improve the utilization rate of regenerative braking energy, realizes dynamic balance between power generation and load, has the characteristics of environmental protection, energy conservation and safety in use, and is suitable for popularization and application.
