The invention provides a full-through type single-phase traction power supply system simulation device, which is characterized by comprising n single-phase AC-DC converters for simulating n trains, a single-phase transformer, a three-phase AC-DC converter AD, a three-phase bus TPB, a single-phase bus TAB and a measurement and control instrument MC, and n is greater than or equal to 2; the single-phase bus TAB is connected to a single phase of the three-phase bus TPB through a feeder line, the n single-phase AC-DC converters are connected to the single-phase bus TAB and are isolated through the single-phase transformer, the three-phase AC-DC converter AD is connected to the three-phase bus TPB, the n single-phase AC-DC converters and the three-phase AC-DC converter AD form an AC-DC-AC converter, and the three-phase AC-DC converter AD is connected to the three-phase bus TPB. The measurement and control instrument MC controls operation of the n single-phase AC-DC converters and the three-phase AC-DC converters AD. The traction network can be simulated to implement in-phase communication, the electric energy of the regenerative train can be better utilized by the traction train, the power consumption of a power system is reduced, and the energy-saving effect is greatly improved.
