【摘要】 图形界面是电力调度自动化系统中不可缺少的部分，图库一体化是图形发展的趋势，本文对此进行了比较深入的研究，采用图形平台、自定义图元和自定义属性三个模块来实现图库一体化，可以在不改变程序的情况下无缝地实现图元和数据库的改变，提高了图形系统的开放性和灵活性。 论文采用总分结构，首先介绍了系统的整体设计思路，从软件开发的角度详细介绍了图形平台中关键技术的设计和实现方法，对其中的主要功能提出了较详细的设计方案和流程图。然后详细介绍了图元自定义和属性自定义两个模块的实现方法，对其中的主要功能做了简明的阐述。最后概要介绍了在图库一体化平台上实现理论线损计算的设计框架，从实践的角度验证了该图形平台良好的开放性和可扩展性。更多还原

【Abstract】 Graphical user interface is a very important part of SCADA system, and integration of graph and database is a trend of graphical technology. The thesis makes some applied research in this area. With three modules of graph platform, user defined graphic elements and user defined attribute we can finish the integration. And we can change the graphic elements and database efficiently without changing the program, and it can make the graph system openly and agile much more.The thesis first analyzes the design method used in the graph system ,some important design methods are proposed from the perspective of software development in detail, and some solutions and data flow diagrams are proposed too. Subsequently the thesis introduce the method of design the two modules of user defined graphic elements and user defined attribute in detail. Finally, the author gives a frame of calculating theory line loss on the graph system. This can prove the graph system is openly and extendable.更多还原
