Embodiment 1

[0074] Such as figure 1 As shown, a method for checking abnormal electricity consumption according to an embodiment of the present invention includes:

[0075] Step S101: Obtain the first user information of the electric meter to be detected stored in the master station, and read the electricity consumption information and the second user information of the electric meter to be detected.

[0076] The method of the embodiment of the present invention obtains the first user information of the electric meter to be detected (the electric meter user information stored in the main station) through the main station (marketing system / metering automation system of the electric power company), and simultaneously through infrared, RFID (Radio Frequency Identification, radio frequency identification technology) to read the power consumption information of the meter to be detected and the second user information (actual user information of the meter to be detected) on the spot.

Embodiment 2

[0095] Such as figure 2 As shown, the description of "calculating the suspected indicator of abnormal electricity consumption based on the preset method for calculating the suspected indicator of abnormal electricity consumption and the electricity consumption information" in step S103 of the first embodiment includes the following steps:

[0096] Step S201: Assign corresponding index weights to each type of sub-information in the electricity consumption information; the electricity consumption information includes one or more types of event record sub-information, electricity quantity sub-information, load sub-information and line loss sub-information.

[0097] Preferably, the electricity usage information includes at least two types of sub-information. In the embodiment of the present invention, the above-mentioned electricity consumption information is classified, specifically, it can be divided into event category, power category, load category, line loss category, etc., ...

Embodiment 3

[0136] The embodiment of the present invention specifically describes a method for checking abnormal electricity consumption. In this embodiment, the electricity consumption information can be specifically divided into event categories, electric quantity categories, load categories, and line loss categories, and abnormal electricity consumption information is established for each category. Check the models, and calculate the indicators through each model separately. Among them, ELI is based on a full score of 100 points, and the proportion of various types in the overall evaluation is 40% for events, 40% for electricity, 10% for loads, and 10% for line losses.

[0137] For the sub-information of the event class, the schematic diagram of the event class judgment process can be found in image 3 shown, including the following steps:

[0138] Step S301: Through the recorded events such as voltage loss, total voltage loss, phase failure, current loss, reverse phase sequence, reve...

Abstract

The invention discloses an electricity utilization anomaly detection method and an electricity utilization anomaly detection device. The method includes the following steps that: the first user information of an ammeter to be detected, which is stored by a master station, is acquired, and the electricity utilization information of the ammeter to be detected and second user information are read; and the first user information is compared with the second user information, when the first user information is inconsistent with the second user information, it is determined that electricity utilization anomalies appear. With the electricity utilization anomaly detection method provided by the embodiments of the invention adopted, electricity utilization inspectors of electric power companies can be assisted to rapidly and accurately position electricity utilization anomaly positions, and therefore, electricity utilization inspection efficiency can be improved, inspection difficulty can be greatly reduced, and time and effort can be saved.

Description

technical field [0001] The invention relates to the technical field of electric power detection, in particular to a method and device for abnormal power consumption inspection. Background technique [0002] Since my country's reform and opening up, economic development and social progress have made remarkable achievements. With the development of the economy, the demand for electricity continues to expand, and the expansion of the electricity sales market has stimulated the development of the entire electricity production. However, with the development of the economy and the increase of electricity consumption, especially with the establishment of the market economy system, the problem of abnormal electricity consumption has become more and more prominent, which not only caused huge economic losses to the country and the power management department, but also seriously disturbed It disrupts the normal order of power supply and consumption, even causes fires, damages power su...
