摘　　要：在电力调度行业,往往有专用系统提供了厂站接线图等动态图形的显示与刷新;然而,一般均不支持以Web方式作进一步的网络发布。SVG是由W3C制订的用于维护二维矢量图形的一种标记语言,借助其内置脚本的强大功能,SVG图像具备了丰富的动态图形表达能力,可高效地实现数据的实时刷新。为此,本文提出了先将动态图形转换为SVG格式、再作Web发布的思路,并给出了具体的转换方法,以及实现动态数据刷新的模型和方法。作为一种将电力调度动态图形转换为SVG格式并作Web动态发布的实用技术,完全可以成为实现将第三方专用系统动态图形显示界面进一步作为Web方式网络发布的一种有效解决方案。In the electricity dispatching filed,there are always specialized systems to provide the display and refresh of dynamic graphs.But,dynamic graphs generally won't be further published through Web.SVG is a markup language made by W3C to maintain 2-dimensional vector graphs.SVG graphs have sufficient expressions of dynamic graphs,which can realize real-time data refresh efficiently.According to the above,this article put forward the idea that convert dynamic graphs to SVG format at first,and then publish through Web.It also gave the detailed conversion method,as well as the implementation of real-time da- ta refresh and modeling.As an applicable technology,this method can be used as an effective solution to publish through Web in the format of a dynamic graphic interface of a third-party specialized system.
