为实现电网企业在电网经济运行中对电网设备进行图形化编辑、数据准备与显示等功能,利用最新软件技术构建了面向服务的浏览器/服务器(B/S)模式电网主接线图形编辑系统。采用Silverlight 2.0技术实现了电网设备矢量图形元件的绘制和图形在客户端浏览器中的编辑功能,服务器端采用分层架构并在后台数据库中存储设备图形业务数据。客户端通过调用服务器端的Window通信基础(WCF)服务数据访问接口,实现了设备图形数据在Silverlight程序与服务器端之间的远程数据通信。系统在满足电网企业业务需求的同时,解决了图形多用户环境下的数据共享问题,面向服务的系统架构降低了系统的耦合性,改善了传统的基于客户/服务器(C/S)模式架构的图形编辑系统在安装、部署和维护升级等方面的不足,提高了电网企业的工作效率。
In order to realize the functions of grid equipment such as graphic editing, data preparation and display during the economic operation of power grid, the grid enterprise has constructed service oriented browser / server (B / S) mode main line graphic editing system based on the latest software technology. Silverlight 2.0 technology is used to realize the drawing of vector graphic elements of grid equipment and the editing function of graphic in client browser. The server adopts hierarchical architecture and stores the graphic data of equipment in the backstage database. Client calls the server-side Window Communication Foundation (WCF) service data access interface to realize the remote data communication between the device graphic data and the Silverlight program and the server. The system solves the problem of data sharing in the multi-user environment while satisfying the business needs of power grids. The service-oriented system architecture reduces the coupling of the system and improves the traditional C / S mode architecture Graphics editing system in the installation, deployment and maintenance upgrades, etc., to improve the work efficiency of power grid enterprises.
