摘　　要：随着电力系统的迅速发展,以标签点为主线存储数据信息的实时历史数据库,在电力系统发挥着重要的作用,然而实时历史数据库系统在信息集成、共享、处理等方面比较复杂,理论规范缺乏。因此建立一个容易扩展、开放性好、存取效率高、数据模型规范输配电网模型软件对促进实时历史数据库电力系统发展有重要意义。公共信息模型(CIM)为电力系统资源提供了可靠的理论依据,本文通过分析CIM模型和关系模型的特点,提出了关系模型与对象模型间的映射关系,在实时历史数据库中建立了CIM库,并证明了公共信息模型对象能够在实时历史数据库中正确存储,分析了实时历史数据库的特点,建立了数据字典,提高了查询效率,实现跨平台、跨系统的业务集成,为提升电网的核心业务能力提供理论化支撑,向全面建成智能电网目标迈进。With the rapid development of power system, with a label for real-time history database main storage data information, plays an important role in the power system, but the history of real-time database system integration, sharing, information processing in the complex, the lack of normative theory. Therefore, it is important to establish an easy to expand, open, efficient access, data model specification transmission and distribution network model software to promote the development of real- time history database power system. The common information model （CIM） to provide a reliable theoretical basis for the power system resources, this paper discusses the characteristics of the CIM model and the relational model, proposes the mapping relationship between the model and the object model of the real-time database is established in the history of the CIM library, and it is proved that the public information model object can be stored correctly in real-time and history database in the analysis of the characteristics of real-time and history database, a data dictionary, improve the query efficiency, realize the cross platform and cross system business integration, to provide theoretical support for improving the grid core business ability to complete the goal of smart grid.
