基于中间件技术的电网在线监测数据集成系统设计

Design of Database Integration of Grid Online Monitoring System Based on Middleware

随着智能电网建设的发展,在大型变电站的主要设备及输电线路安装在线监测系统,已成为输变电运行、维护管理的有效手段。但随着在线监测系统的不断增加,"信息孤岛"问题愈发突出,直接增加了管理的复杂度。因此,需要集成这些独立在线监测系统以实现信息共享,即实现异构数据集成。介绍了电网检测系统数据的集成特点和中间件数据集成技术,通过对异构数据集成的主要目标和关键问题分析,提出了基于中间件、XML和JMS的异构数据库集成解决方案,以解决原有各类在线监测系统异构数据源之间的数据统一查询、共享和发布问题。

With the development of smart grids, the on-line monitoring system for major equipment and transmission lines has become an effective means for the operation and maintenance of the power transmission facilities in large substations. With increasing of on-line monitoring systems however, the＂information isolated island＂ problem has become more and more prominent, which directly complicates the management. Therefore, there is an urgent need to integrate these independent on-line monitoring systems and realize sharing of the information, namely, realize the integration of heterogeneous data. To this end, this paper, firstly introduces the characteristics of the data integration for the on-line monitoring systems for power grids and then the middleware data integration. Based on an analysis of the main goal of the heterogeneous data integration and the key problems, the paper proposes a data integration solution based on middleware and the heterogeneous database for XML and JMS so as to realize the data source query, sharing, and publishing among the heterogeneous data of all kinds of the original on- line monitoring systems.
