摘    要:网络拓扑是电力系统分析软件的基础,而采用可视化的方法实现网络拓扑的建立则是可视化能量管理系统(EMS)的核心,作者提出了一种面向对象的抽象电力网络拓扑模型,建立了一种通用的拓扑描述方法,该方法具有很好的可扩充性,在图形数据库一体化的平台上,实现了一种利用矢量图的坐标关系自动生成拓扑的快速算法,该方法的核心思想是压缩参与拓扑形成的图数和采用分区方法来减少计算量。利用所提出的面向对象的网络拓扑模型,实现了一种新的高效的基于节点融合的拓扑模型,实现了一种新的高效的基于节点融合的拓扑方法,并利用该方法,开发了监视控制与数据采集(SCADA)动态着色和调度员培训仿真系统(DTS)的调度操作校核等实用程序。

关 键 词:电力系统分析软件  图形数据库  网络拓扑  面向对象

Abstract:Network topology is the basis of power system analysis software and it is also the kernel of visualized EMS to establish network topology by visualized method.In this paper an abstract object oriented model for power network topology is put forward and a versatile and easily expandable representing method of power system topology is built up.On the integrated platform of graphic database a fast algorithm which can automatically and quickly generate topology by use of coordinate relations in vectorgram is realized.The core of this method is that the calculation workload can be decreased by compressing the number of graph icons taken both part in the topology formation and by using a partitioning method.Adopting the presented object oriented network topology model,a novel topology algorithm for network tracking based on node merging is implemented,and with this algorithm the applied programs such as dynamic colouring in SCADA and checkup of dispatching operation in DTS,etc.,are developed.
Keywords:network topology  graphic database  object  oriented
