基于Web服务的变电站信息系统的研究

Study about transformer substation information system based on Web service

分析了当前电力系统信息运作的现状,指出由于各地信息系统所处的操作系统、数据库平台的不同,导致相互间不能实现信息共享,形成的一个个“信息孤岛”。文章提出使用W eb服务的方式解决这一难题的方法,针对变电站的实际情况进行了需求分析和功能划分,并对系统的框架(前台采用Struts框架、后台采用基于EJB的W eb服务方式)以及实现的大致过程做了介绍。论文结尾对W eb服务技术及其应用作了总结和展望。

This paper firstly analyzes the current situation of the electric power system information operation, and points out the shortages： low efficiency; easy to make mistakes and the information can not be shared to form ＂isolated information islands＂ because of different platform of OS and database of information system. Web Service is adopted to solve this problem. Aiming at the real situation of substation the requirement analysis and function division of the project are given out. The paper introduces the system structure and the implementation, the Struts structure is used on the foreground while the Web Service based on EJB is used on the background. Finally the paper summarizes the Web Service technology and its applications.
