The invention discloses a controllable series compensation device, and belongs to the technical field of electrical control. In order to save electricity, eliminate third harmonics and reduce cost and complexity, a scheme that a harmonic-free three-phase magnetically controlled reactor formed by a main winding, isolation windings and direct-current control windings which are wound on a squirrel-cage three-phase three-column symmetrical iron core as well as a three-phase direct-current control power supply is connected with a capacitor bank in parallel is adopted, wherein one ends of the isolation windings are mutually connected, and the other ends are connected with an input end of the three-phase direct-current control power supply; and the direct-current control windings are connected in series and then connected in parallel, and two ends of the direct-current control windings are connected with the positive end and the negative end of the three-phase direct-current control power supply.
