时间序列数据库在地区电网调控一体化系统中的应用

摘要

本文在分析地区电网调控一体化系统特点的基础上,提出了在系统中引入时间序列数据库的设计方案,将Oracle数据库与国产时间序列数据库结合使用,解决了关系型数据库在系统使用中存储和访问效率等方面的问题。介绍了所开发的时间序列数据库服务及其主要功能应用,如实时曲线、事故反演、历史潮流、可视化调度等。%By analyzing the characteristics of an integrated system for dispatch and control of regional power systems,an embedded time sequence database scheme combining the Oracle database and a database developed in China is presented.The presented scheme can solve some problems,such as the storage and data access inefficiency in running a relational database.Services associated with and main application functions of the time sequence database are introduced,such as displaying real time curves and historical power flow data,as well as the inversion power accident and visualized dispatch.
