The invention relates to a fault pre-judgment method and system based on digital twinning, and the method comprises the steps: obtaining an abnormal signal position in response to an obtained abnormal signal; obtaining an information acquisition terminal associated with the position of the abnormal signal, and obtaining feedback information of each information acquisition terminal; comparing any two pieces of feedback information to obtain a difference result; grouping the difference results; judging the severity of the fault according to a group of difference results; and shielding an abnormal signal containing a difference result corresponding to one accurate position or one fuzzy region, and reducing the number of the obtained accurate positions or fuzzy regions according to the residual feedback information. According to the fault pre-judgment method and system based on digital twinning disclosed by the invention, the abnormal operation area of the power grid is found through analysis and mining of the ac
