Non-contact power load decomposition sensing method and system

Abstract

The invention discloses a non-contact power load decomposition sensing method and system. The method mainly comprises the following steps of training based on an original current, an active current and a reactive current which are obtained in a non-contact mode to obtain a first neural network unit; obtaining a second neural network unit based on the information extracted from the input data of the first neural network unit by the first neural network unit and the original current training; and deploying the second neural network unit in a power system for performing the monitoring operation of power load decomposition sensing. According to the embodiment of the invention, the working state of an electric device in a circuit can be analyzed only in an induced current input manner on the premise that an existing electric circuit is not cut off or modified, and the recognition precision of an algorithm can be maximized under the limitation of only depending on the induction current input.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and system for non-contact electric load decomposition sensing. Background technique [0002] With the rapid development of smart grid and artificial intelligence Internet of Things technology, the analysis of household energy consumption and the understanding of user behavior based on electricity consumption have gradually become a hot technology development direction. The existing implementation scheme of electricity consumption situation analysis is mainly to install corresponding sensors on each household appliance, and obtain electricity consumption parameter information through the sensors. This implementation solution not only has the disadvantage of high cost, but also makes the maintenance cost and complexity of the entire system relatively high. [0003] Based on the above problems, the academic community proposed the technical concept of non-intrusive loa...

AI Technical Summary

Problems solved by technology

[0004] At present, there have been some related research work in the world and a variety of algorithms have been introduced to solve the problem of non-intrusive load monitoring, but the main limitation of these works is that, Because the existing algorithm needs to measure time-synchronized voltage and current data as input, and the precise measurement of voltage needs to be involved in the power system, so it is necessary to cut off the circuit to install and deploy the sensor

During the installation and deployment process, there may be hidden dangers of power interruption, fire and electric shock

Moreover, considering the mandatory need for high reliability of energy supply such as server rooms or urban public infrastructure, it is obviously difficult to deploy the deployment method of cutting lines in the above scenarios
