摘　　要：以某电力系统为研究背景,在对原有的数据源进行分析和重新组织的基础上,构建电网调度数据仓库,并建立多维雪花模式的数据立方体。运用OLAP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,实现负荷预估和调度的科学化,并说明OLAP数据仓库能够为电网调度管理人员提供有效的决策信息。A real power system is selected as the research background. Based on analyzing and reorganizing the originally existing dada sources, the power system dispatch data warehouse is formed and snowflake mode cubes for multi-dimension data are established. By using OLAP and data mining technology, forecasting load, analyzing and inquiring data warehouse are realized from different point view and multi-layers. It shows that the system is able to provide the valid decision-making information for the dispatchers and managers in power system.
