The invention provides an intelligent traction substation and a power flow control method therefor, and relates to the technical field of electrified railway power supply. The substation comprises a traction transformer TT, a power flow control device PCD and a controller CC. A primary side of the traction transformer TT is connected to a three-phase power grid; one end of a secondary side is connected to a traction bus TSB, and the other end is grounded. The traction bus TSB is connected, via a feeder F, to a traction network OCS that uses two-way feeding power supply. The controller CC is configured to control, according to electric quantity information of the traction bus TSB and the feeder F, the power flow control device PCD to carry out negative sequence compensation on the traction transformer TT, such that the negative sequence meets national standards. The controller CC is further configured to control the power flow control device PCD to utilize, via power supply to a power distribution system or by energy storage means, generated power flow returned to the traction substation from the traction network OCS to enable the generated power flow returned to the power grid to meet a preset requirement.
