摘　　要：文章提出电力系统可视化计算图形平台的图形编辑与拓扑分析需要双向支持的观点,一是以电力设备元件为单位绘制电网图形的方式,从图形分析电网拓扑;二是根据基于关联矩阵的拓扑描述,自动生成各种电网图形,并可继续图形编辑。设计出图形--拓扑双向支持的架构。建立统一的底层数据模型,包括数据结构、元件模型、节点数组和边数组。提出图形拓扑分析的有效方法和基于关联矩阵的拓扑描述。完善多功能的可视化界面,包括图形的编辑、图形切换、图形缩放、图形存储等。实现基于元件的网络拓扑分析和基于已有拓扑的图形再现。An idea is proposed that the graphic platform of power system visualization calculation needs bidirectional support for graphic-editing and topology-analysis. On one hand, to draw a power grid graphic using electrical elements, analyze the topology of the grid in graphics; On the other hand, based on the incidence matrix topology description, each power grid graphic is outputted automatically, and can be edited continuously. The structure of graphics-topology bidirectional support is designed. The basic data model id constructed, including data structure, element model, nod array and edge array. An effective method of graphic-topology-analysis and the topology description based on incidence matrix are proposed. The multi-functional interface is consummated, including graphic- editing, graphic-switching, graphic-zooming and graphic-storing. The functions that grid-topology-analysis based on elements and graphic-redisplaying based on topology are achieved.
