异构电力信息系统中异构数据库间的数据导换方法

DATA TRANSMISSION AMONG ISOMERIC DATABASE IN MULTIPLE ISOMERIC ELECTRIC POWER SYSTEM

电力系统中存在不同结构、不同运行机制的信息系统 ,各系统相互独立 ,应用平台和数据库结构存在差异 ,而且存在大量的重复数据。针对这一问题 ,文中以电能量采集与分析系统和负荷控制系统间的数据导换为例 ,提出了基于 Internet浏览器 ,利用 Delphi面向对象的数据库编程技术 ,以及 Sybase服务器、MS SQL Server服务器并用 ,对异构信息系统的异构数据库进行数据导换的方法 ,通过对档案的动态增加、删除、修改实现档案的统一 ,实现了对异构电力信息系统的数据的统一管理 。

There are different structures and operation mechanisms in the power system, which are independent from each other. There also exist some differences on the application flat top building and plenty of duplicated data. Take the data transmission from the electric energy acquisition and analysis system to the load control system as an example, a new method is proposed, based on Internet Browser, using Delphi object oriented database programming technology, and Sybase database and SQL Server database simultaneously. Through the dynamic adding, deleting and altering of the archives, the unified management on isomeric database data of isomeric information system can be achieved to improve the function of the integrated system.
