上海电力负荷数据库设计

Database design for Shanghai electric load

为了有效管理电厂中用于负荷预测、调峰决策、性能分析等的大量数据,必须建立一个有效的数据库来提高电厂信息管理系统的安全性和可靠性。在详细分析了电厂数据库系统设计要求的基础上,采用关系数据库原理、VisualC++的DAO数据库访问方法、SQL查询语言等有关知识设计了一个关系数据库,该数据库为电厂工作人员提供一个包含所有有关机组参数在内的数据集合。

In order to enhance the security and reliability of the information management system for power plant ,an effective database is necessary for managing the huge data in load forecasting,peak-load shedding and performance analysis.A power plant relation database is designed based on the detail analysis of its requirements,which adopts relation database principle,Visual C++DAO and SQL.It provides a data aggregation,including all relevant unit parameters,for power plant operators.
