摘　　要：基于某品牌60家便利店为期一年的用电监测数据,本文采用正态性检验与频数分布分析法,建立了连锁便利店行业用电需要系数的科学取值标准。考虑到便利店设备安装容量与运行负荷存在显著差异,本文样本数据经检验符合正态分布(P=007),其需要系数呈现048~075的波动区间。通过建立安装容量分级模型,提出当设备总功率≥70kW时,需要系数建议取045~055,较现行设计取值降低375%~438%。研究成果有效解决了《商店建筑电气设计规范》中便利店用电指标缺失导致的过度设计问题,可为同类商业业态提供负荷计算依据,实测应用显示可降低电力增容需求达62%,单店年节约配电投资32万~56万元。Based on the power consumption data of 60 chain convenience stores in one year,this paper establishes a scientific criteria of the electricity demand coefficients for chain convenience stores by using the analysis method of normality test and frequency distribution.With consideration of the difference between the installed capacity and actual load,the electricity demand coefficients vary within 0.48~0.75 in accordance with the normal distribution of P=0.07.Meanwhile,by establishing a hierarchical model,this paper gives suggestions for the electricity demand coefficient with 0.45~0.55 for systemswith the total power≥70kW,which is less than 37.5%~43.8%by comparing with the current value.This paper can effectively solve the issue of overdesign in the existing《Electrical Design Norm of Commercial Buildings》and gives reference to other buildings.The practical applications validate this paper with capacity of decreasing the power demands by 62%and power investment by 32,000~56,000 per store.
