摘　　要：为了解决电能量计费系统中要保存大量历史数据的数据库技术问题,采用分布式实时数据库系统技术.具体介绍了分布式实时数据库系统的基本结构,以及CPU调度算法、I/O调度算法、事务提交协议、并发控制协议。从电力企业需求出发,在电能量计费系统TMR中应用分布式实时数据库,实现了跨操作系统的电能量计费,降低了网络流量,提高了各节点的数据查询速度,从而提高系统的响应速度,为进行实时的线损计算提供了基础。In order to solve the problem of electric energy metering system to save a large amount of historical data of database technology, the distributed real-time database system technology. Specifically introduces the distributed real-time database system＇s basic structure, as well as CPU algorithm, I/O algorithm, transaction commit protocol, a concurrency control protocol. The electric power enterprise needs, in the electric energy metering system TMR application of distributed real-time database, realizes cross operating system of electric energy metering, reduces network traffic, improve on each node of the data query speed, thereby improving the response speed of the system, for the real-time line loss calculation provides the basis for.
