Non-intrusive electrical appliance identification method based on Frechet distance

Abstract

The invention discloses a non-intrusive electrical appliance identification method based on Frechet distance, and solves the problems that a traditional power consumption monitoring method is high incost and difficult to deploy, and early non-intrusive monitoring has insufficient hardware and algorithms. The method only relies on electrical appliance steady state current and voltage data, has lowrequirements on the hardware, and only needs to collect the data of a single device in the early stage, sample data does not need to be combined with electrical appliance data to reduce the data collection, the algorithm is simple and can be easily integrated into a hardware device, and the method is easy to promote.

Description

technical field [0001] The invention relates to the technical field of electrical appliance identification under a non-invasive detection system, in particular to a non-invasive electrical appliance identification method based on Fréchet distance. Background technique [0002] In the 1970s, the United States and some European countries began to study household energy consumption in order to improve household electricity efficiency and realize energy conservation and emission reduction. In recent years, with the development of sensing technology, information communication technology and control technology, especially the rise of smart grid, the task of home energy management system is also increasing, and the premise of realizing this task is to effectively control various electrical appliances. monitor. Power load monitoring is of great significance to both households and power companies. For households: they can clearly understand the power consumption of each type of elec...

Problems solved by technology

[0004] Traditional intrusive detection, by adding corresponding sensor shunts to various electrical appliances to achieve metering, and then realize the power consumption monitoring of the total electrical appliances, the investment is relatively large, and it is easy to cause interference to the normal operation of electrical appliances. Too many line connections make User acceptance is not very good

[0005] The non-intrusive detection power consumption proposed earlier is based on the unit current of the electrical appliance category, which can only decompose the category and cannot be refined to specific electrical appliances.

Moreover, most of them rely on the transient characteristic data of electrical appliances, which requires high hardware and correspondingly increases the cost, which is not conducive to the promotion of products; and some of the algorithms are too complicated to be integrated into hardware devices, and there are too many training data A lot of labor costs are required in the early stage
