针对我国电力用户数据采集点规模大、采集密集的特点，分析了智能电网建设中用电信息采集系统对数据库的需求，从系统组成、系统技术架构、数据库部署方案以及建设模式等方面研究了实时/历史数据库在用电信息采集系统中的建设方案。该方案能够保证数据采集的可靠性，提升数据应用的敏捷性，具有即插即用的数据接口通用性、创新性的数据流应用展现以及独特的数据保姆功能。该建设方案的应用可为实施分时电价进行预研，为指导社会科学合理用电提供参考。

Aiming at large-scale data collection points and intensive collecting characteristics of power users in our country, the demands on database of electric energy data acquire system are analyzed in the construction of smart grid. The construction plans of real time database in electric energy data acquire system are discussed from the system composition, technical architecture, database deployment, and the construction models etc. The program can ensure the reliability of data collection, enhance the agility of data applications, have universal data interface with plug and play, show the innovative application of data flow, and have the function of unique data nanny. The application of the construction plan is pre-research of implementing time-of-use(TOU) and makes the basis of guiding the social scientific and rational use of electricity.
