摘　　要：为提升电网智能化、数字化水平,针对变电站逻辑模型的建模、移交及展示3个方面提出一套完整的变电站数字化移交应用研究方案。首先研究了变电站逻辑模型建模总构架、数据库文件建模格式和数字化信息交互的方案,通过将逻辑模型中的抽象概念与实体概念相结合,设计出合理的数据结构,实现逻辑模型的全数字化表达;其次对移交格式、导入导出接口进行了详细的阐述,开发了数字化全景逻辑模型信息展示平台,将数字化逻辑模型信息与三维模型相关联,并用于展示变电站相关数字化信息。所提数字化设计的逻辑模型移交研究是对变电站纯物理模型移交的一个补充,为数字化电网发展提供基础。To improve the intelligent and digital level of power grid, in allusion to the three aspects of modeling, handover and display of the logical model of substation, a complete set of application research scheme of substation digital handover was proposed. Firstly, the general framework of substation logical model modeling, the database file modeling format and the digital information interaction were researched,and by means of combining the abstract conception in the logical model with the entity concept a rational data structure was designed to realize the full digital expression of the logical model. Secondly, the handover format and import/export interface were expounded in detail, and a digital panoramic logic model information display platform was developed to associate the digital logical model information with the 3D model to display the digital information related to the substation. The proposed research on the handover of logical model of digital design is a supplement to the pure physical model handover of substation and provides the basis for the development of digital power grid.
