摘　　要：提出一种基于邻接矩阵的厂站拓扑分析方法,并介绍了采用图形数据库一体化技术实现该方法的具体步骤。通过在电气图形编辑界面设置绘图网格,使得连通的电气图形元件具有相同的端点坐标,分析这些坐标可以判断电气图形的连通性情况,进而通过对厂站模型中各开关、结点的编号,形成厂站的结点-开关关联矩阵;推导结点-开关关联矩阵,最终得到表示厂站拓扑关系的结点邻接矩阵。该方法较传统的拓扑方法具有更好的通用性和可扩充性,通过程序软件实现并验证了该方法的正确性。A station topology analysis method based on adjacent matrix is presented and the graphic database integrative technology is adopted to realize it. The drawing grid is set on the electrical graphic editing interface for locating the elements connected with same coordinates. Those coordinates can identify the connected status of all the elements. The program numbers all switches and nodes through searching the connected branches to form a node-switch adjacent matrix. Inferring the node-switch adjacent matrix will get the final node adjacent matrix. This method has better generality and expandability than traditional topology methods,and its correctness is verified through program.
