摘要
智能化变电站监控系统集成了各个应用系统的数据。文章描述了在多应用数据集成的情况下,采用基于中间件的数据源集成方式,通过CIM模型进行异构数据源的映射,并采用发布订阅机制为不同应用提供通用的数据访问服务,实现应用对变电站端不同数据源的通用访问功能,实现应用对数据访问的无关性,增强了不同自动化系统间的互操作性,在智能变电站中有较好的应用前景。
The intelligent substation monitoring system integrates data from various applications. In case of various applications data integration, this paper describes a multiple data sources integration method based on the middleware technology, proposes a heterogeneous data source mapping method using the CIM model, provides universal data access services for different applications using the subscription and distribution mechanism, and develops a general function for applications to access multiple data sources of substations. The solution that applying CIM-based universal data access service to intelligent substations makes loose coupling between data and applications, enhances interoperability of different automatic systems, and will be a good application prospect in intelligent substations.
