电网调控集群分布式实时数据库的设计与关键技术

摘要

In order to solve the problem of processing performance of large-scale real-time data in power dispatching and control systems,a cluster based distributed real-time database is designed,which uses distributed technologies to achieve massive data storage and cluster technologies to achieve uniform data access and management.Key technologies of cluster based real-time database are discussed including distributed storage,distributed data location and distributed data access.The problem of flexible slicing,large-scale data storage and fast data locating of real-time data in a power dispatching and control system is also solved.Testing and on-site system verification prove that the cluster based distributed real-time database system is able to achieve high efficient data access and the condition of high reliability of the system is ensured.%为解决电网调度控制系统大规模实时数据的处理性能问题,设计了一种集群分布式实时数据库,通过分布式技术实现海量数据存储,并使用集群技术实现数据的统一访问和管理.对集群分布式实时库架构及所使用的分布式存储技术、分布式数据定位技术和分布式访问技术进行了讨论,解决了调度控制系统实时数据的灵活分片、分布式存储和快速定位问题.最后通过测试和现场运行验证了集群分布式实时数据库能在确保系统高可靠性的条件下,实现实时数据的高性能访问.
