The invention relates to an AC/DC excitation magnetic saturation-type controllable shunt reactor, which comprises an oil tank, magnetic core columns disposed in the oil tank, and left and right side magnetic yokes and upper and lower magnetic yokes forming an iron core magnetic circuit structure for the magnetic core columns, wherein the magnetic core column is sleeved with a control winding, a compensation winding and a grid side winding in sequence outwardly from a column surface; the grid side winding is connected with a transmission line, the compensation winding is connected with the input end of a rectifying and filtering device, and the control winding is connected with the output end of the rectifying and filtering device; one grid side winding sleeves two magnetic core columns; each compensation winding is located at the inner side of the grid side winding; and each magnetic core column is sleeved with one control winding. The control is flexible, the response time is fast, the reactive power of the
