摘　　要：我国长期面临区域性、季节性、时段性、结构性的缺电现象,而有序用电工作可促进电力供需平衡,保障居民生活和重要用户的用电。但目前编制有序用电方案时,参与有序用电的用户选择主观性强,缺乏科学依据,有失合理与公正。本文提出了有序用电用户可中断负荷分析方法,通过对用户的历史负荷进行聚类,得到用户的几类典型日负荷曲线,并对典型负荷曲线按采样点进行聚类,综合分析得到用户的用电规律和用电时段等负荷信息,进一步可计算出用户的避峰、错时、轮休、检修价值,在此基础上制定用户参与有序用电的准则和策略,并可向社会公开,使得编制方案和有序用电的执行有标准可依,更加有序。Our country has been long-term facing the regional, seasonal, periodical and structural shortage of power. Orderly power utilization is a tool to keep balance in supply and demand of power and so as to ensure the power supply to residential and important demanders. However, currently choosing demanders to participate into orderly power utilization program is mostly subjectively decided by the operator, which is lacking of scientific basis, unreasonable and injustice. This paper proposes a load characteristic analysis method for orderly power utilization demanders based on fine management object.Through clustering the historical load of the demanders, typical daily load curve of demanders are figured out. Then through combining the sampling points clusters of typical daily load curve, power utilization pattern and power utilization interval of demanders are obtained. The peak load shifting and holiday staggering plan value of the demanders are calculated. Rules and strategies for orderly power utilization demander selection are constituted based on the analysis of load property, which, is public to the community, makes the orderly power utilization work more scientifically and orderly.
