Abstract In view of the defect of single evaluation method for power grid technological transformation projects, the restriction of the original evaluation method is broken and the problem that the former post-evaluation method for technological transformation projects is greatly influenced by experts' subjectivity is avoided. In this paper, the matter-element extension evaluation method is introduced, and the post-evaluation model of technological transformation project based on the whole life cycle is established. The in-depth research is carried out from seven aspects of the project's preliminary work, project implementation preparation, project implementation management, final accounts management, file management, project investment control and project operation performance. Based on the comprehensive evaluation and analysis of the self-renovation and protection and replacement project of Suzhou 500kV Shipai substation, the practicability and effectiveness of the model are verified, which provides theoretical and technical support for guiding the post-evaluation work of technological transformation projects and strengthening technological transformation management work in the future.
