电力系统智能图形支撑平台的研究

图形用户界面是电力系统应用软件不可缺少的一部分，为减少图形系统的重复开发，构建一个开放的图形支撑平台十分必要。文章以软件工程的设计思想为指导，对电力系统智能图形支撑平台应具有的功能和应遵循的设计原则进行了系统的分析和研究，提出了分层模型和图形数据分离等设计方法，使图形系统具有可重用性、开放性和可拓性。同时，对离线编辑和实时运行模式的不同要求进行了讨论。据此进行了图形系统的开发，取得了良好的效果。

Studies of the intelligent graphic supporting platform for power systems

The graphic user interface(GUI) is necessary in the application software for power systems. To reduce the repetition in graphic systems development, a graphic supporting platform becomes much important. Based on the concept of software engineering, this paper systematically analyzes the functions and design principle of intelligent graphic supporting platform for power systems, and then proposes some design methods, such as the hierarchical model and the dissociation technique in graphic and data, which makes the graphic system reusable, opening and extensible. The difference between the requirements of offline edit and real-time operation is also discussed. A graphic system has been developed to demonstrate the effectiveness of the proposed method.
