THDS-100调度自动化系统中数据形象化的关键技术

KEY TECHNIQUES OF VISUALIZING DATA IN THDS—100 DISPATCHING AUTOMATION SYSTEM

数据是电网调度自动化系统运行的根本所在 ,但是抽象的数据缺乏可读性和可理解性。现代先进的计算机技术 ,特别是图象、图形技术提供了变抽象为形象的重要途径 ,更使得调度自动化系统焕然一新。文章介绍了调度自动化系统中曲线显示功能模块使用的 5项关键技术 ,即语义网络组织查询、查询优化 (数据用户和数据提供者 )、多输出缓冲区、数据跟踪和主副进程间遥控。采用这些技术的主要目的是把数据库和前台调度员界面更直接地连接起来 ,实现抽象数据的形象化 ,提高调度员的工作效率 ,同时实现工作过程的优化。

As the foundation of operation, data are of great importance to dispatching automation system. However, abstract data are to some extent abstruse, greatly harming the performance of dispatching automation system. Modern computer techniques, especially image and graphic techniques, provide us a brand-new approach to visualize the data and change the whole visage of dispatching automation system. In this paper, five key techniques used in the graphic module of dispatching automation system are presented, namely construction of data requests via semantic network, optimization of data request (data users and data providers), multiple output buffer, data tracking, communication and interaction between primary process and associate processes. These techniques are helpful to connect databases with user interface directly, visualize the abstract data, improve the efficiency of dispatchers and optimize the whole process of electric power system.
