摘　　要：电力系统负荷建模是一项十分重要,同时也是非常困难的工作,目前为止还没有建立起广域的和常效的机制。本文提出利用各电压等级安装到户的智能电表开展广域的负荷建模工作,分别利用智能电表功率信息,通过在线统计综合法获得负荷模型,以及将智能电表作为在线测辨装置,利用实时采样数据在线测辨获得负荷模型,构建了基于智能电表的广域负荷建模体系。通过自动抄表系统定期将负荷统计与测辨相关信息分层收集,分级建模,逐级向上,可实现电力系统负荷信息的广域统计、分析与校核,从而建立动态和长效机制,有效推动负荷建模的各项研究工作。Power system load modeling is a very important and difficult work. Up to now there is no wide area and long-term mechanism for it.This paper proposed a wide area electric load modeling measurement based on smart meter installed everywhere in the power grid. It uses online component based methodology with power and reactive power information to get the load model, and the smart meter as online measurement device to get the load model at same time to build up a wide area load modeling structure.The load information can be retrieved from the smart meter through the automatic meter reading system and implement wide area statistic, analysis and verification of electric load andj provide precise load composition, proportion and time varying characteristic. The smart meter based load modeling measurement will promote the study and research on electric load modeling greatly.
