摘要
对于变电站不同时期开发的分散控制系统,实现其数据共享和集成是全面建设整个变电站监控信息系统(supervisory information system,SIS)的关键。为此,提出了一种基于可扩展标记语言(extensible markuplanguage,XML)的异构数据集成技术,并构造了一个以XML为数据交换格式,使用XML schema建立公共模型、Mediator集成模式的异构数据源集成中间件HDSIM,实现了变电站数据采集、监视、分析和保护一体化。最后给出了系统应用实例,应用结果表明了这种数据集成技术的有效性。
As for the distributed control system (DCS) developed in different times, how to share and integrate the data of DCSs plays an important role in building the comprehensive supervisory information system (SIS) in a substation. This paper proposed heterogeneous data sharing and integration technology based on extensible markup language (XML) and constructed a kind of heterogeneous data sources integration Middleware (HDSIM),which uses XML as the data exchange format and makes XML schema establish a public model with Mediator integration pattern, to achieve the integration of data collection, monitoring, analysis and protection in the substation. Finally, the results of the application confirm the validity of this data integration technology.
