基于OLAP技术的电力客户能效评估模型

Energy efficiency evaluation model for power customers based on OLAP technology

为了提高电力客户的能源利用效率,基于OLAP技术建立了电力客户能效评估模型.通过介绍和分析OLAP技术的概念与工作原理,确定评估模型的状态因素集合,设计了电力客户能效评估的指标体系,同时引入下钻和上卷等数据处理方法,建立了电力客户的能效评估模型.使用原始能效数据,对能效评估模型进行了理论性评估和分析.结果表明,该评估模型理论上可以明显评估客户电能使用的科学性,实现节约能源和降低污染的目的.

In order to improve the energy efficiency of power customers,an energy efficiency evaluation model based on OLAP technology was established.Through the introduction and analysis of both concept and working principle of OLAP technology,the state factor set of evaluation model was determined,the index system of energy efficiency evaluation of power customers was designed,and the data processing methods,e.g.drill-down and roll-up,were incorporated to establish the energy efficiency evaluation model.In addition,by using the original energy efficiency data,the energy efficiency evaluation model was theoretically evaluated and analyzed.The results show that the as-proposed evaluation model can evaluate the scientificity of electric energy usage by customers theoretically,and achieve the purpose of saving energy and reducing pollution.
