摘要
交互式图形系统中图元的属性和服务差别较大,有必要对它们建立统一的数据模型。采用了CIM标准来构建交互式图形系统中图元的电气模型,并把图元的几何模型合并到电气模型中,形成对CIM扩展过后的图元的综合数据模型。图形系统中的各种电力参数都可以通过图元的综合数据模型统筹起来,这使得图形系统的内部结构变得清晰,为进一步构建适合电力系统分析计算和管理应用的通用交互式图形系统奠定了基础。
Service and property of graphic elements in the graphic system is distinctive,so it is necessary to establish a unified data model.The paper makes use of the data model of graphic element based on CIM.Graphic element is the fundamental unit in interactive graphic system,which is abstract image of physical electrical equipment.All parameters in the graphic system can be planned as a whole in the data model.The data model of graphic element can be used to establish interactive graphic system which has convenient function in the calculation,analysis and management of the power system.
