Abstract

The invention relates to a grading anti-stealing system and a method, which are applied in electrical distribution network. The system comprises a plurality of electric charge collecting devices respectively arranged at each negative charge of a power supply circuit and at relevant negative charges on all branch power supply circuits of the negative charge according to the topological structure of an electrical distribution network; a data transmission device for transmitting the realtime electric charge information collected by the plurality of electric charge collection devices; and a monitor center for receiving the realtime electric charge information transmitted by the data transmission device for storage, analyzing the difference between inflow charges and out charges and the line loss at each node in a power network and comparing the line loss with the normal line loss of the node to determine whether an electricity-stealing suspicious node is present.

Description

technical field [0001] The invention relates to a power management technology, in particular to a hierarchical anti-theft system and method. Background technique [0002] With the development of the economy, the dependence of various fields of the national economy on electric energy continues to increase. At the same time, it has also caused some lawbreakers to ignore laws and regulations and use technology to steal electricity. At present, the 10kV distribution network in my country's power system is a The link with the largest proportion, the solution to the problem of anti-stealing will help to improve the economic benefits of the power supply system and ensure the safe operation of the distribution network. Unscrupulous users have hidden means of stealing electricity, and there are many ways to steal electricity. At present, the technical means adopted to prevent electricity theft are mainly divided into three categories: [0003] The first type is to add a new type of ...
