Technical Field

[0002] With the continuous development of society and the advancement of science and technology, electricity has become the basic energy source for modern social life and production; however, the power system faces many challenges in its operation, among which electricity theft is a long-standing problem that is difficult to completely solve; electricity theft not only causes economic losses to power companies, but also has a negative impact on the stable operation of the power system and the rational allocation of power resources. Therefore, how to effectively prevent electricity theft has become a key issue of concern to power companies and scientific researchers.

[0003] Electricity theft is mainly manifested in users stealing electricity through illegal means, common methods include privately connecting wires, tampering with meter data, using strong magnetic interference meters, etc. These behaviors not only cause direct economic losses to power companies, but also affect the stable operation of the power grid and increase the maintenance and replacement costs of equipment. In addition, electricity theft also poses great safety hazards, which may cause fires, electric shocks and other accidents, endangering public safety. Traditional anti-electricity theft methods mainly rely on manual inspections and fixed monitoring equipment, such as regularly dispatching staff to check meters and lines. This method is not only time-consuming and labor-intensive, but also difficult to detect in time due to the concealment of electricity theft. In addition, traditional meters lack intelligent functions and cannot monitor electricity usage in real time, making it difficult to trace and obtain evidence after electricity theft occurs.

When electricity theft is detected, the system can quickly dispatch engineers to handle it according to the preset maintenance strategy. By obtaining the address of the electricity theft user and the address of the engineer, the system calculates and sorts the travel time and selects the most suitable engineer to handle it on-site during the time period when the electricity theft user often steals electricity. This real-time monitoring and rapid response mechanism ensures that electricity theft can be handled in the shortest time, reducing the loss of the power company and improving the safety and stability of users' electricity use.

[0193] Through the cooperation of the intelligent data collection terminal, server and line loss test module, electricity theft can be efficiently identified and located; the intelligent data collection terminal consists of a total smart meter and sub-smart meters. The total smart meter records the total electricity consumption of all users, and the sub-smart meter records the electricity consumption of each user respectively; by comparing the records of the total smart meter and the sub-smart meter, the system can calculate the line loss rate and determine whether there is electricity theft; in addition, the system has also designed a detailed strategy for finding electricity theft users, and further confirms the identity of the electricity theft users by analyzing the user's historical electricity consumption data and abnormal time periods; this method of precise positioning and identification not only improves the detection efficiency, but also reduces the false alarm rate, ensuring that electricity theft can be discovered and handled in a timely manner.

[0195] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention.
