The invention is suitable for the technical field of electrified railways, and provides an energy management device in a traction power supply system and the traction power supply system. The device comprises a first power instruction calculation unit, a second power instruction calculation unit, a central processing unit, an alpha-phase bus signal acquisition module, a beta-phase bus signal acquisition module, an alpha-phase feeder signal acquisition module and a beta-phase feeder signal acquisition module. The first power instruction calculation unit is used for calculating alpha-phase power according to the alpha-phase feeder signal and the alpha-phase bus signal; the second power instruction calculation unit is used for calculating beta-phase power according to the beta-phase feeder signal and the beta-phase bus signal; and the central processing unit is used for generating an energy control instruction for controlling the railway power regulator to perform energy management according to the alpha-phase power and the beta-phase power. The alpha-phase power and the beta-phase power are calculated by collecting the feeder line signals, the problem that the collection working condition is inaccurate after an energy storage device is additionally arranged on a line can be avoided, and the signal collection accuracy is improved.
