水电站厂内经济运行数据库系统的开发与应用

Development and application of inner-plant economical operation database system within a hydropower station

数据库系统是水电站厂内经济运行系统的核心。采用实时数据库和历史数据库相集成的方式,运用可视化语言创建库引擎,开发了水电站厂内经济运行数据库系统。该数据库系统为水电站厂内经济运行系统提供了从数据创建、使用到维护的统一管理,为系统提供了实时的或历史的数据服务。研究结果表明,它具有响应快、扩充性好和使用方便等特点,可以为其他水电站高级应用软件的数据库开发提供借鉴。

Database system is the core of the inner-plant economical operation software for hydropower station. Based on the composition of real-time database and history database. The inner-plant economical operation of hydropower stahion was built with visual computer language and database management system. The hydropower stations with the consolidated management of data building, operation and maintaining, as well as real-time/ history database service were provied. The resahs of research show that the system has the characteristics of quick response, good extension, convenience etc. and provides reference for the development of advanced application software in other hydropower stations.
