The present invention provides an intelligent electric meter user missing voltage data restoration method. The method comprises the steps of: obtaining user voltage data of a zone area based on a power utilization information collection system; calculating an average value of voltage difference values of users at corresponding moment; according to the size of the average value of the user voltagedifferences, providing user grouping basis, and performing grouping of the users; and according to a grouping result, providing a user missing voltage correction method, and correcting user missing voltage data between groups. The intelligent electric meter user missing voltage data restoration method can achieve restoration of intelligent electric meter user missing voltage data so as to provideimportant data basis for development of related business.
