基于元件与量测相结合的负荷特性数据库系统

Load characteristics database system based on component and measurement

以电网综合负荷特性的调查统计数据和在变电站现场采集的负荷特性数据为基础,采用VisualBasic6.0开发工具和SQLServer2000数据库平台,开发了一个电力系统综合负荷特性数据库系统,并成功地应用于基于元件和基于量测两种途径的综合负荷建模。阐述了综合负荷特性数据的来源和特点以及数据库的基本结构和功能设计,着重描述了数据库的具体设计方法和技术。实际运行表明,该数据库系统具有结构完整、界面友好、操作方便、运行可靠、扩展性好等特点,为电力系统综合负荷建模及负荷特性研究提供了技术支持。

Using Visual Basic 6.0 as developing tool and SQL 2000 as database platform,a data- base system of aggregate load characteristics data is developed based on the investigated and measured data from power network,which is applicable to both measurement-based and component -based load modeling. The sources and characters of aggregate load characteristics data are expounded. The essential structure and function design of the database is described,with the design method and technologies emphasized. Practices show that it has complete structure,friendly interface,convenient manipulation,reliable operation and good expansibility. It provides technological support to power system aggregate load modeling and load characteristics research.
