文档介绍：摘要
电力自动化系统是应用控制技术、计算机信息处理技术和通信技术,通过计算机
软、硬件或自动装置代替人工进行各种运行作业,提高电力系统运行、管理水平的一
种自动化系统。在电力自动化系统中变电站/电站监控系统属于上位机部分,其软件
设计及程序运行与计算机操作系统平台密不可分,在当前电力自动化系统中各种工控
机上运行着各种平台,而且在未来一段时间内仍将是多种操作系统平台共存,能够兼
容多种操作系统平台是电力组态软件未来发展的方向之一。
本文从分析监控系统的结构和功能入手,讨论跨平台实现过程中的重点和难点,
比较各种平台之间的差异以及相关开发语言工具之间的性能优劣,总结出一套比较合
适跨平台解决方案。本文通过介绍Qt这种新型的程序开发工具包,将其应用到电力组
态软件的设计开发中,在数据库访问以及图形用户界面的开发上克服操作系统之间的
不兼容性,从而实现整个系统的跨平台能力。在此技术基础上成功开发出一套应用于
变电站/电站的SCADA监控系统,包括实时数据库、绘图包、人机交换程序、数据通讯
与采集模块以及管理维护模块,并顺利在多个平台上测试通过。
此外作为客户机-服务器模式的补充,以及跨平台在基于互联网的解决方案,本
文还简单了介绍了基于浏览器-服务器模式的电力组态软件所涉及到的问题和技术,
并提出了采用Flash技术来设计Web应用程序的方案。

Abstract
Electrical automation system applies control technology, computer information
technology munication technology. It can do all kinds of operation automatically
puter software and hardware instead of manual work. It is a system that raises
power system operation and management standard. Monitor and control systems of
substation/hydropower station belong to puter part in the electrical automation
system. Their software design and program running have close relationship to operation
system of puter, which are various in the existing electrical automation system
application. Furthermore, the situation of the various operation systems coexisting in the
electrical automation system will be lasting for a long time in the future, so the
development of Configuration Software which patible with multi-operation system is
urgent affairs.
The dissertation begins with structure and functionalities of the supervisor and control
system, followed by the discussing of emphases and difficulties of the implementation of
multi-operation system Configuration Software. And then the pares the
difference of the platforms and the capabilities of developing tools. Based on this, a
solution scheme fitting the requests of multi-operation system is given. This dissertation
shows a means to achieve patibility and the c
