目前,电力系统的图形信息表示的格式还没有统一的标准,不能实现不通系统间的兼容和共享。针对图形模块构建过程中的种种难题,本文把目光转向了可扩展标记语言XML和SVG,其中SVG是一种基于XML的描述矢量图形的文本格式语言。文中提出了基于XML和SVG的电力系统图形信息表示的方法,研究了SVG在电力系统设备图形化描述中的应用,并和IEC61850的系统图结构模型结合起来,实现图形信息的标准化。在次基础上,设计了基于B/S结构的电力系统图形发布系统模型的结构和工作流程,实现了该系统与用户的交互查询功能,对客户端实时数据的动态展示进行了研究。
At present, the graph express format of power system has not been standardized. It isn"tcompatible, and cannot be shared. To solve the questions in the process of the graph moduleconstruction, we changed the vision to eXtensible Markup Language – XML and ScalableVector Graphics – SVG, which is based on the XML and is used to descript vector graph inthe form of the text. In the paper, a method to express the graph information of power systembased on XML and SVG is proposed. We discuss how to use SVG to express the powersystem devices" graph information, then research hoe to unify with the IEC61850 diagramstructural model to realize graph information standardized. On the base of the research, thepaper designs a model based on the B/S structure, which is used to issue the power systemgraph through network. The structure and the work flow of the model are discussed. Finally,the model function is partially realized, for instance the inquiry of equipment simple attributeinformation. At last, the paper analyses dynamic demonstration of real-time data in the clients"Browser.
