The invention discloses an active-disturbance-rejection control method for a through same-phase traction power supply system, and the method comprises the steps: building a dual-loop active-disturbance-rejection voltage control strategy of an inverter side of a static power converter through an inverter side model of the static power converter, the inverter side model of the static power converter is constructed by working parameters penetrating through the in-phase traction power supply system; based on a double-loop active-disturbance-rejection voltage control strategy, an outer loop controller is used for generating a reference value of a filter capacitor current by feeding back a contact network voltage, and an active-disturbance-rejection controller is used as an inner loop controller for generating a reference value of a converter output voltage by feeding back a converter output current; and according to the reference value of the filtering capacitor current and the reference value of the output voltage of the converter, performing voltage control on the inversion side of the static power converter in the through same-phase traction power supply system. Therefore, the voltage control system has good anti-interference performance and transient characteristics, is easy for engineering realization, and can be applied to a single-phase alternating current system.
