The invention provides a power grid disturbance source positioning method based on integrated oscillators. The method comprises the steps that fundamental oscillators are determined; a principal component analysis method is used to determine the integrated oscillators; and a power grid disturbance source is positioned according to the integrated oscillators. According to the invention, the principal component analysis method is used to calculate the integrated oscillators; the importance of related oscillators is reflected in the form of contribution rate; oscillation integrated index values are sorted; a power plant with a unit with the largest oscillation integrated index value is positioned as the power plant with the disturbance source; the relative importance of different oscillators is considered in the form of index contribution rate; integrated analysis is carried out on disturbance features from multiple angles; indexes of different natures and different dimensions in a plurality of fundamental oscillators are integrated into the integrated oscillators; according to the sorting of the integrated oscillators, the power grid disturbance source is accurately positioned.
