Abstract Smart management of energy management have got more and more significant due to the growing awareness of the environmental protection and domestic energy cost, in which the core is how to improve the efficiency of domestic energy consumption. Although the existing methods regarding the improvement of energy efficiency manage the appliance by means of monitoring the consumption displayed on the smart meter, the smart meter measures aggregate consumption for an entire building. Research has shown that disaggregated information describing each appliance consumes is more effective than aggregated information. This paper presents several disaggregation techniques, and analyzes their advantages and disadvantages. Keywords: Smart Meter; Disaggregating the Data; Household Electricity Cost; Environmental Protection; Wise Management of Energy Consumption

要:随着家庭用电成本控制和环境保护意识的增强,智能用电管理变得越来越重要。如何提高家庭用电效率是智能

用电管理的核心内容之一。已有提高用电效率的办法就是通过智能电能表监测电能消耗情况,从而管理电器使用。但是 智能电能表记录的是用户总体用电数据。研究表明,对于指导用户高效使用电器,描述单台电器的用电信息比用户总体 用电数据作用更大。本文介绍了几种从智能电能表数据中解析出单台电器用电信息的技术,并分析了各自的特点。 关键词:智能电能表;数据解析;家庭用电成本;环境保护;用电智能管理

引言 智能用电管理变得越来越重要。一方面,家庭电器增多,用电量随之上升,用电费用增加;另一方面, 大气环境保护形势严峻,减少用电量,有助于减少化石燃料消耗和 CO2 排放。 如何提高用户用电效率是智能用电管理的核心内容之一。已有提高用电效率的办法就是通过智能电能表 监测电能消耗情况,从而管理电器使用。但是,智能电能表计量的是用户总体用电情况。研究表明,对于电 器使用的有效管理,描述单台电器的用电信息比用户总体用电数据作用更大[1]。 智能电能表数据解析技术能够从智能电能表数据中解析出单台电器的用电信息。虽然早在 1980 年精密 电能表就第一次成功应用数据解析技术,但是由于精密电能表的推广应用受到了挑战,所以智能电能表数据 解析技术仍是目前的研究热点。 本论文介绍了几种智能电能表数据解析技术,并分析了各自的特点。
