【摘要】 研究和制定配电系统运行管理数据库的数据结构和规范是当前我国配电自动化实施过程中亟待解决的问题。针对我国配电系统结构以及配电生产运行管理的特点 ,分析了供电企业中各部门之间的工作联系 ,提出了配电系统运行数据、检修与巡视数据以及设备资产与网络拓扑数据的数据流图。这 3个数据流图可以描述配电系统基本数据的产生、加工和传递全过程。在此基础上 ,采用面向对象的分析方法组织配电数据信息 ,建立了配电数据的全局ER模型并转换成相应的关系模式更多还原

【Abstract】 Data models and standards for distribution automation databases are needed urgently by distribution automation projects in China. By analyzing features of power distribution operation and management, data flow graphs of operation data, maintenance and patrol data, and assets and topological data for power service utilities were proposed. These three data flow graphs can be used to describe the whole procedures of data generation, data procession and data transfers in power distribution services. Based on these graphs Entity-Relationship models and their relational modules for distribution automation database were developed.更多还原
