Semi-invasive household load monitoring method

Abstract

The invention relates to the technical field of intelligent power utilization, and discloses a semi-intrusive household load monitoring method. The method comprises the steps of S1, configuring current sensors of multiple branch circuit and a voltage sensor of a main circuit into a household distribution box, and monitoring power utilization information of each branch circuit; S2, acquiring the power utilization information of each branch circuit based on a multi-channel signal sampling mode; and S3, analyzing and calculating the acquired power utilization information of each branch circuit ina multi-circuit parallel processing mode, and outputting a monitoring result. According to the invention, one sensor is configured in each branch air circuit breaker circuit by combining characteristics of electric energy distribution of the household distribution box, and all the sensors are configured in the household distribution box, so that the sensors are concentrated in the same space, theconfiguration quantity of the sensors is greatly reduced, the implementation cost is reduced, and the operability and the user acceptance degree are improved.

Description

technical field [0001] The invention relates to the technical field of intelligent electricity utilization, in particular to a semi-invasive household load monitoring method. Background technique [0002] Smart power consumption is an important part of the smart grid and the basis of the interactive service system between the power sector and power users, and power load monitoring is the primary link to realize smart power consumption. Household electricity load monitoring technology refers to the identification of each household appliance and monitoring of its operating status through sampling and analysis of electricity load data, so as to obtain data information such as power consumption and electricity consumption behavior of each household appliance. , Realize the lean service of household electricity consumption. [0003] At present, there are mainly two ways to realize household electricity load monitoring: intrusive load monitoring and non-intrusive load monitoring....

Problems solved by technology

Among them, the intrusive load monitoring method means that each household appliance in the house is equipped with a power consumption information monitoring sensor with a digital communication function, and the monitored power consumption information is transmitted to the master station for processing. Although the monitoring data of this method is reliable, the Poor operability, high implementation cost, and low user acceptance due to the large number and spurious spatial distribution of sensors and communication modules

The non-intrusive load monitoring method means that only one sensor is installed at the household entry line to identify different types of household appliances and monitor the working status of each appliance by collecting and analyzing the total current and terminal voltage of household electricity. Low cost and strong practical operability have recently attracted more attention. However, due to the wide variety of household appliances and the complex waveform of the total current of household electrical loads, the non-intrusive load monitoring method for household electrical consumption is difficult due to the difficulty of the algorithm and the monitoring accuracy is not good.
