Electricity larceny prevention method
Technical Field
The invention relates to the technical field of power utilization management, in particular to an electricity larceny prevention method.
Background
The modern society is established in an energy system based on electric power, the power supply guarantee of an electric power enterprise is very important for ensuring the development of economy and the production and life of residents, and the power supply enterprise greatly ensures the electricity utilization safety of the residents by adopting a 'one-household one-meter' mode, strengthening the transformation of a power supply and distribution line, adopting an electric energy meter with larger capacity and the like. But discover in the power supply operation of electric power enterprise, the action of stealing, steal the electricity still takes place occasionally, also caused serious influence to power supply unit's safety when seriously haring the economic benefits of power supply enterprise, along with the improvement of science and technology with prevent stealing, the improvement of the means of stealing the electricity, steal the electricity action also more conceals and be difficult to guard against, the safe operation of giving electric power enterprise has brought very big potential safety hazard, electric power enterprise need construct perfect prevent steal, steal the electric security system, guarantee the safe and reliable operation of electric power supply conscientiously.
The existing electricity stealing prevention technology has two main ways, one is that various electricity stealing prevention hardware measures are installed at the place where the electric energy meter is installed and on the meter, and the purpose of preventing electricity stealing is achieved. And secondly, judging whether the electricity stealing behavior exists or not by the difference value between the total electric energy output and the electric energy use of each household meter. However, both methods have a number of disadvantages: 1) the two electric meter methods are undoubtedly the most measures for finding the electricity stealing behavior of the users, but the installation of the two-way electric meter method undoubtedly increases the hardware investment of the electric meter, and the investment of the part is relatively large, the number of electricity stealing users is small compared with that of non-electricity stealing users, and the investment of the electric power system is increased by adopting the two electric meter methods; 2) the electric energy difference method of the electric energy general meter and the individual meter can save a large amount of investment, but factors such as errors in topological relation between the general meter and the individual meter, inaccurate calculation of low-voltage line loss, meter metering errors and the like exist, so that accurate judgment on electricity stealing cannot be realized. The electricity utilization monitoring personnel are required to be familiar with the responsible area to play a certain role. Therefore, it is highly desirable to invent a method for avoiding fraudulent use of electricity with low cost and high accuracy without adding fraudulent use of electricity equipment.
