摘　　要：为了研究不同行业春节期间的负荷用电特性差异以及春节前后对用电的影响时长差异、用电量变化情况,进一步制定春节期间合理的需求侧管理措施。本项目以2019年春节期间即除夕前后各45天来研究武汉市整体、重点行业及工业代表性典型企业春节前后用电数据为基础,引入时序、气温、节假日等影响因素,通过相关分析、聚类分析。研究主要成果如下:(1)第二产业、第三产业、工业代表性企业的春节前后用电主要分为三类:“U型”用电特征、“M型”用电特征、“多峰型”用电特征;(2)第二产业受春节假期的影响在时间跨度和影响程度上均明显高于第三产业,但各行业受春节影响的时间长度有所不同;(3)整体来看,第三产业春节前后用电与温度相关性相对较高于第二产业,第二产业春节前后用电与温度相关性普遍较低。In order to study the differences in load power consumption characteristics of different industries during the Spring Festival,as well as the influence time difference and electricity consumption change before and after the Spring Festival,reasonable demand-side management measures during the Spring Festival are further developed.This project is based on the study of the electricity consumption data of Wuhan as a whole,key industries and typical industrial enterprises before and after the Spring Festival during the Spring Festival in 2019,i.e.,45 days before and after the New Year’s Eve.It introduces timing,temperature,holidays and other influencing factors,and makes correlation analysis and cluster analysis.The main results of the research are as follows:(1)The electricity consumption of the secondary,tertiary and industrial representative enterprises before and after the Spring Festival can be divided into three categories:"U-shaped","M-shaped"and"multi-peak";(2)The second industry is significantly affected by the Spring Festival holiday in terms of time span and degree,but different industries are affected by the Spring Festival for different lengths of time;(3)On the whole,the correlation between electricity consumption and temperature in the tertiary industry before and after the Spring Festival is relatively higher than that in the secondary industry,and the correlation between electricity consumption and temperature is generally low.
