摘要
分析了电力调度对数据分析与处理的新需求 ,提出利用多年积累的自动化系统采集的数据进行综合分析、处理 ,提供电力调度辅助决策的设计思想 ;给出基于数据挖掘技术的电力调度数据仓库的基本特征 ,采用最新的 Microsoft SQL Server2 0 0 0建立了电力调度数据仓库 ,提供基于浏览器和电子表格的联机分析工具 ;并在电网线损分析、电力负荷与气象相关性分析方面进行了数据挖掘的初步尝试。
This paper investigates the new requirements of power dispatching on data processing and analyzing, and proposes to utilize the data accumulated by SCADA/EMS in order to support decision-making on power dispatching. The basic properties of the data warehouse based on Microsoft SQL Server 2000, on-line analysis process (OLAP) tool with browser and Microsoft excel are also introduced. This has been initially applied to data mining on power network loses as well as relationship between power load and weather.
