Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] like figure 1 As shown, a method for analyzing user electricity composition provided by the present invention includes the following steps:

[0027] S1-1: Collect the steady-state power information of the specified user's household appliances through the smart meter, and draw the power load curve;

[0028] S2-1: After step S1-1, according to the electric energy load curve, the actual combination curve and the fitting combination curve of different home appliances under different working conditions are established;

[0029] S3-1: After step S2-1, compare the similarity between the actual combination curve and the fitted combination curve, and obtain the electricity consumption composition data of the monitored users;

[0030] S1-2: While step S1-1 is being executed, user information is collected and the meteorological information of the user's surrounding envir...

Abstract

The invention relates to the technical field of electric engineering and more specifically relates to a user electricity consumption structure analyzing method. Based on a data mining technology, steady state electricity information of home appliances of a user is acquired through a smart electricity meter. Load elastic time of the user is identified according to different time scales and different external environments, and more accurate user electricity consumption analyzing result is acquired. The analyzing method provided by the invention combines factors including user family conditions,environment factors and the like. The accuracy of the acquired user electricity consumption structure analyzing result is improved and a more scientific data support is provided for planning and execution of schemes such as power grid performance reconstruction and the like.

Description

technical field [0001] The present invention relates to the technical field of electrical engineering, and more specifically, to a method for analyzing user power consumption composition. Background technique [0002] Analysis of user electricity consumption composition is a process of decomposing the electricity consumption of residential users into the specific electricity consumption of a single or a type of household appliances based on the limited electricity consumption information of residential users. Through the analysis of the user's power consumption composition, it is possible to discover unnecessary power consumption, discover energy-saving points, and reduce electricity bills. At present, the analysis of user power consumption mainly adopts the non-intrusive load monitoring method. By installing monitoring equipment at the power inlet and monitoring the output voltage, current and other new models, the type and operation status of a single load in the cluster c...
