电网调度广域分布式实时数据库系统的存储和访问技术

Research on storage and access technology of wide-area distributed real-time database system for power dispatching automation system

为了适应多个调度系统间对实时数据的共享需求,文章设计了一种广域分布式实时数据库,对已有的实时库模块进行广域分布式扩展,把广域网络内各个独立的实时数据库子系统从逻辑上整合成一体化的大型分布式实时数据库。广域范围内的实时数据通过ID关键字和设备名两种方式统一构成实时数据统一标识,并根据标识实现了数据的快速访问,解决了广域范围内的实时数据存储和处理能力。最后通过现场运行,提升了省地调系统支撑平台的实时数据处理能力。

In order to meet the requirements of real-time data sharing among multiple scheduling systems,this paper designs a wide area distributed real-time database,extends the existing real-time library modules,and logically integrates each independent real-time database subsystem in the wide area network into an integrated large-scale distributed real-time database.The real-time data in the wide area is identified by ID keyword and device name,and fast access to data based on identification,which solves the real-time data storage and processing capacity in the wide area.Finally,through on-site operation,it improves the real-time data processing ability of the supporting platform of the provincial land dispatching system.
