The invention relates to an archive management system for a power overhaul engineering project. The system comprises an early-stage engineering module, a construction recording module, an overhaul management module, a completion management module and a user management module, wherein the early-stage engineering module is used for classifying and managing archives made in the early-stage engineering preparation process of a power overhaul engineering project; the construction recording module is used for classifying and managing archives made in the engineering construction process of the poweroverhaul engineering project; the overhaul management module is used for classifying and managing archives made in the engineering overhaul process of the power overhaul engineering project; the completion management module is used for classifying and managing archives made in the engineering completion acceptance process of the power overhaul engineering project; and the user management module is used for carrying out right management on users of the archive management system. By adopting the archive management system, the efficiency in storing and calling various archives can be improved, the integrity of the archive management system is improved, automatic management of electronic archives is achieved, waste of labor sources is reduced, data can be automatically updated, various budgetestimation reports can be automatically generated, archive revealing can be effectively prevented, and the archive management security is improved.
