Power transformation engineering data management method and device, computer equipment and storage medium

The invention relates to a power transformation engineering data management method and device, computer equipment and a storage medium. The method comprises the following steps: in each project stage of a power transformation project, obtaining stage data of a project object in the project stage and circulation data of a previous project stage, and storing the stage data and the circulation data in a data model diagram of the project stage; the data model graph is constructed according to the format of the graph database; extracting shared data of the engineering stage from the data model diagram, and updating the shared data to obtain circulation data of the engineering stage; transferring the transfer data of the engineering stage to the next engineering stage, updating the next engineering stage to the engineering stage, and returning to the step of storing the stage data of the engineering stage and the transfer data of the previous engineering stage into the data model diagram of the engineering stage.
