New-type real-time electricity larceny prevention method

Abstract

The invention discloses a new-type real-time electricity larceny prevention method, comprising the following steps: when a power grid operates normally and no electricity larceny occurs, according to the electricity using information reported by users, developing the theoretical node admittance matrix for the power grid and updating it in real time; during the actual operation of the power grid, scanning the states of the various nodes of the power grid that access the power grid to obtain the self-admittance and the mutual admittance of the various nodes too develop the actual node admittance matrix of the power grid; and comparing the actual node admittance matrix and the theoretical node admittance matrix to see if electricity larceny occurs or not. According to the invention, the node admittance matrix of a power grid in a region is utilized to realize the real-time monitoring of the loads in the region so as to determine whether electricity larceny occurs in the region or not. Since the electricity state comparison method is adopted featuring no numerical calculations, the detection precision is increased greatly; the chances of under-reporting or mis-reporting of electricity larceny can be avoided; in addition, the electricity larceny can be determined according to the network state in a direct manner.

Description

technical field [0001] The invention specifically relates to a novel real-time electricity-stealing prevention method. Background technique [0002] With the development of national economy and technology and the improvement of people's living standards, electric energy has become an indispensable secondary energy source in people's production and life, bringing endless convenience to people's production and life. As an intangible commodity, electricity is an indispensable consumer product in modern society. The user must pay the electricity fee on time according to the electricity fee approved by the state and the record of the electric energy metering device. At present, the phenomenon of power theft in our country is becoming more and more serious, which makes the already prominent contradiction between power supply and demand more acute. It destroys the order of power consumption, disturbs the economic environment, and seriously damages the economic benefits of power su...

The second is for the theft of electricity outside the meter. If the electricity is connected to the line of the power supply department without reporting to the household, or the meter user dumps the meter without permission, this kind of behavior will not only cause the power loss of the power department. At the same time, it may also cause overload damage to lines and public transformers due to private connection and random use of electricity, which can easily cause personal casualties and fires and other major accidents.

At present, the way to prevent electricity theft outside the meter is mainly to compare whether the sum of the electric energy or current of the main meter and the electric energy or current of the sub-meter is consistent. If the difference is beyond the threshold, there is electricity stealing. There is a certain distance, the cross-sectional area of ​​the wire, the material, the wiring method, etc. will affect the value in the meter. At the same time, the meter itself will also have a certain power loss. The application is very immature, and the power consumption of the technology or the deviation of the data record will affect the correct judgment
