specific Embodiment approach

[0047] Such as Figure 1~3 As shown, it shows a specific embodiment of the present invention;

[0048] figure 1 It is the general flowchart of the matching identification method for electric load triple reliability.

[0049] Firstly, the total current, voltage, power and other power consumption information is measured from the main entrance of the power user, and then the power consumption data is processed and screened. Secondly, the power load is triple-matched using the load characteristic database of different granularity, and the triple-matching is performed again. The result is corrected, and finally the load identification result is output.

[0050] The basic idea of ​​the triple matching is: "Power fingerprints detect exceptions, transient fingerprints detect mutations, and steady-state fingerprints detect operating loads. Power fingerprints match transient fingerprints in real time, and steady-state fingerprints match regularly.

[0051] figure 2 It is the triple...

Abstract

The invention discloses a tri-reliability matching and identification method of electric load. With the method, information of power consumption ratio of all kinds of electrical appliances of electric users and device starting and stopping time can be reliably identified and the method is used for assisting the electric users and electric power companies to carry out electric consumption planning and management. The method comprises following steps of S1: acquiring electrical load data and establishing characteristic database of different granularities of electrical load; S2: acquiring electrical load data at the entrance of a user general power supply, wherein the electrical load data comprises voltage, current and power data; S3: using the tri-reliability matching and identification algorithm to resolve the electrical load data in real time; and S4: according to output results of the tri-reliability matching and identification algorithm, carrying out output display on power consumption ratio of all kinds of electrical appliances, and starting and closing time of the electrical appliances.

Description

technical field [0001] The invention relates to an electric load reliability matching identification method, which is specifically used for the electric load identification and the measurement of the reliability in the electric power system. Background technique [0002] The identification of power load reliability is to collect power consumption data such as voltage, current, and power at the total power source of power users, and decompose the power consumption ratio of the electric equipment turned on by the user in real time according to the power load characteristics of different granularities, and obtain The degree of reliability of classifying a certain type of unknown electrical equipment as known equipment is shown. [0003] The existing load identification technology mainly uses a single feature of the electric load, such as the power feature or the current harmonic feature for identification, and the reliability and credibility of the identification results are po...
