摘要
随着电力工业的发展,各个应用系统之间信息共享和应用集成需求凸现出来,迫切的需要不同系统间都遵循一个标准的、开放的电力系统信息模型,并提供通用的数据接口。CIM模型和CIS接口的出现,很好的解决了这一问题。同时由于电力行业需要存储大量的有较高时间约束的数据,将数据存储在内存中,并且定期的将内存中的数据转储到硬盘数据库中,可以有效的提高数据库事务执行效率。其中基于CIM模型的数据在内存中的组织方式是设计的重心。该内存实时数据库在电力监控系统中已经投入使用,并得到了预期的效果。
With the development of power industry, it is urgent that a standard and open power system model is founded. Luckily, CIM model and CIS interface can resolve the problem. At the same time, since the power system industry needs to hold a lot of data that are high time restricted, the data can be stored in a memory real-time database by which the efficiency of database affair will be improved greatly. The structure of the data CIM model based is explained clearly. And the CIM based memory real-time database has been used in the Power Automation System. As a matter of fact, it can meet what the system need.
