摘要

数据的探索性分析在数据挖掘和分析的整体过程中具有举足轻重的作用。主要针对电力数据中具有非正态分布特征的数据进行分析研究。首先，采用统计分析的方法对电力数据中的用电量、售电量和发电量几个核心指标在地域上的分布规律进行统计分析，经验证，这些指标不符合正态分布，并且得到其幂律分布特性；然后，验证了细分行业的用电量符合对数正态分布；最后，结合电力业务背景，挖掘电力数据具有幂律分布以及用电量符合对数正态分布的原因。

Abstract

The explorative analysis plays an important role in the process of data mining. The non-normally distributed data in the electric power data was analyzed. Firstly

the distribution law of generated energy

electricity sales and electricity consumption with statistical methods across the province within the business area of SGCC were analyzed

and it was found that these indices were not normally distributed but follow the power law distribution. Then the electricity consumption of subdivided trade follows the log-normal distribution was proved. At last

the reasons that these data are not normally distributed were given.
