The invention discloses a tidal current control device for a V/v traction substation of an electrified railway. The device consists of a static power adjuster, a TCR filter and an LC filter (FC), wherein the static power adjuster is mounted on the secondary side of the V/v traction substation, and a back-to-back structure is formed by the static power adjuster and a capacity on the public direct current side; the alternating current side of a current converter is connected to power supply arms on the secondary side of the traction substation respectively through a voltage drop transformer; an FC filter is connected to a phase a of the secondary side of the V/v traction substation, and the TCR filter is connected to a phase b of the secondary side of the V/v traction substation. All parameters are calculated by capacity optimization, so that the cost and the system harmonic absorption content can be reduced. A double-closed-loop controller is used for controlling the tidal current distribution of the two power supply arms, so that multi-mode tidal current control is realized; by matching of the V/v traction substation, the TCR filter, the FC filter and the static power adjuster, multi-mode tidal current double-closed-loop control on the traction substation of the electrified railway is realized; voltage fluctuation is suppressed, main harmonics are effectively shielded, and comprehensive negative sequence and reactive treatment is realized.
