The Electrical Monitoring Technology Based on the Non-intrusive Load of the Communit

加强用电设备能耗的监测是我国提高电能利用率、实现能源可持续发展、建设节约型社会的重要手段。通过对国内外用电设备监测技术和方法的研究,以及对几种常用用电设备识别方式、原理和优缺点的比较,提出了一种基于非入侵式负荷的谐波电流面积监测技术。采用该技术对小区用电设备进行Matlab仿真,并对仿真结果进行分析和验证。结果证明该技术能提高用电设备的识别精度和能耗监测效率,对减少小区经济损失、提高电力系统稳定性、实现能源可持续发展具有一定的意义。

Strengthening energy consumption detection of equipment used is essential to improve energy efficiency, achieve a sustainable energy development and to construct a conservation-oriented society. A literature review of the domestic and overseas studies on the monitoring method and technology of electrical equipment and the identification principle, the advantages and disad- vantages of several kinds of commonly used electrical equipment are analyzed. On this basis, a harmonic current area detection tech- nology based on non-intrusive load is proposed in this paper. A Matlab simulation of electricity equipment in a community proves that this technology can improve the precision of the equipment identification and efficiency of the energy consumption monitoring. As a result, this article is significant in improving the stability of the electrical power system, reducing the economic losses in the community and achieving sustainable development of the energy.
