Embodiment 1

[0069] see figure 1 , figure 1 It is a schematic flowchart of a low-voltage electricity theft alarm method provided in the embodiment of the present application. Depend on figure 1 It can be seen that the low-voltage electric stealing alarm method in the present embodiment mainly includes the following steps:

[0070] S1: Collect the zero line current value and live line current value of all current low-voltage users every set time to form a current data set.

[0071] In this embodiment, the set time is 1 hour, and a method of collecting data on the hour every day can be adopted. Specifically, the master station of the acquisition system relays the zero-line current values ​​and live-line current values ​​of all current low-voltage users on the hour every day. The specific relay method is the relay meter reading method in the prior art.

[0072] After the current data set is formed, step S2 is executed: from the current data set, the current data whose zero line current v...

Embodiment 2

[0116] exist figure 1 Based on the example shown see figure 2 , figure 2 It is a schematic structural diagram of a low-voltage electricity theft alarm system provided by the embodiment of the present application. Depend on figure 2 It can be seen that the low-voltage stealing alarm system in this embodiment mainly includes: a current data acquisition module, a screening module, a preprocessing module, a judgment module, a stealing probability calculation model building module, and an alarm module.

[0117] Among them, the current data acquisition module is used to collect the zero-line current value and the live-line current value of all current low-voltage users every set time to form a current data set; The current data whose line current value is inconsistent with the live line current value; the preprocessing module is used to preprocess the current data with inconsistent zero line current value and live line current value of the same low-voltage user, and obtain the...

Abstract

The invention discloses a low-voltage electricity stealing alarm method and system. The method comprises the steps of collecting the zero line current and live line current of a low-voltage user at a set time interval, and forming a current data set; screening data with inconsistent current values from the current data set for preprocessing to obtain a current ratio; comparing whether there is an electric quantity difference value or not between the electric quantity of an electric energy meter in the month before uncovering and the electric quantity of the current month of the collected current data set; if so, establishing an electricity stealing probability calculation model according to the current ratio and the electric quantity difference value; and giving an alarm according to the electricity stealing probability. The system comprises a current data acquisition module, a screening module, a preprocessing module, a judgment module, an electricity stealing probability calculation model establishment module and an alarm module. According to the invention, automatic electricity stealing monitoring can be realized, and the accuracy of current data processing is improved, so that the accuracy of electricity stealing monitoring is improved.

Description

technical field [0001] The present application relates to the technical field of electricity stealing monitoring in a power supply system, in particular to a low-voltage electricity stealing alarm method and system. Background technique [0002] With the rapid development of my country's economy, the demand for electricity loads has grown rapidly. Correspondingly, driven by economic interests, some criminals steal electricity, causing the loss of national electric energy and disrupting the normal order of power supply. Therefore, how to monitor and report to the stealing behavior is an important technical problem. [0003] At present, the method of monitoring the stealing behavior of low-voltage users is usually based on the data on the electricity information collection platform, manually extracting and calling for measurement, so as to determine the specific metering point where the suspicious electricity stealing behavior occurs. Specifically, there are a large amount o...
