| 摘要: |
| 为了实现对电网污区图的智能化管理,以某电力系统为研究背景,在对原有的数据源进行分析、处理和重新组织的基础上,构建电网污区图数据仓库,并建立多维雪花模式的数据立方体。运用在线联机分析处理OLAP(On-Line Analytical Processing)和数据挖掘技术,从多角度、多层次快速地分析和查询数据仓库的数据,实现电网污区图管理的科学化,并为污区图的实时滚动修订提供了技术基础。说明了OLAP数据仓库能够为电网管理人员提供有效的决策信息。 |

| Abstract: |
| With a real power system as the research background and based on the analysis,processing and reorganization of its original dada sources,the data warehouse is formed and the multi-dimension data cubes in snowflake mode are established for the intelligent management of power grid pollution area chart.By using OLAP(On-Line Analytical Processing)and data mining technologies,the quick data inquiry and analysis from different users at different levels are realized for the scientific management and real-time updating of power grid pollution area chart.It shows that OLAP data warehouse may provide effective decision-making information for grid managers. |
| Key words: on-line analytical processing,data warehouse,multi-dimensional data cube,pollution area |
