Research on classification and coding technology of substation engineering model based on 3D design

Under the environmental requirements of three-dimensional design, the coding of the power grid engineering identification system can no longer adapt to the new technical environment and construction needs. In order to be suitable for the three-dimensional design technology environment and meet the requirements of engineering life-cycle management, this paper studies the demand analysis, classification and coding rules. In order to be suitable for the three-dimensional design technology environment and meet the requirements of engineering life-cycle management, this paper studies the demand analysis, classification and coding rules, and In order to be suitable for the three-dimensional design technology environment and meet the requirements of engineering life-cycle management, this paper studies the demand analysis, classification and coding rules, and application scenarios of substation engineering model classification and coding based on three-dimensional design. model classification not only needs to reflect the system composition and hierarchical relationship of substation engineering, but the standardized hierarchical classification Model classification not only needs to reflect the system composition and hierarchical relationship of substation engineering, but the standardized hierarchical classification is also a necessary condition to complete the non-destructive interaction of design models. The classification and coding design principles of three- dimensional design models of substations are put forward, and three-dimensional model coding application methods are proposed, such as identifying model types and equipment asset information, technical and economic financing and cost preparation, and engineering construction The three dimensional model coding application methods are proposed, such as identifying model types and equipment asset information, technical and economic financing and cost preparation, and engineering construction management.
