Problems solved by technology

[0004] (1) Although the on-site manifestations of electricity theft are various, the existing anti-theft measures for various specific electricity theft methods can no longer adapt to the new type of electricity theft
[0005] (2) Due to the failure to effectively integrate the electricity consumption information of electricity customers during the anti-stealing inspection, the anti-stealing inspection is less targeted
[0006] (3) The electricity stealing behavior of users cannot be discovered in time, and some electricity stealing behaviors are often discovered only when the general survey or line loss is abnormal. For the situation of resisting inspection and destroying evidence, the electricity stealing behavior is difficult to find

Abstract

The invention discloses an abnormal electricity utilization judgment method based on abnormal analysis of electric quantity, voltage and current. The abnormal analysis of the electric quantity comprises a fluctuation electric quantity analysis process and a zero electric quantity analysis process, wherein the abnormal analysis of voltage comprises voltage phase-failure abnormal analysis, voltage off-normal abnormal analysis and voltage unbalanced abnormal analysis; the abnormal analysis of current comprises a current loss abnormal analysis and current unbalanced abnormal analysis. By analyzing and comparing abnormal data of electric quantity, voltage and current of the users, real abnormal users or electricity stealing users can be determined. The abnormal electricity utilization judgment method based on the abnormal analysis of the electric quantity, the voltage and the current, disclosed by the invention, has the advantages that electricity information of power users can be timely grasped, the electricity stealing behavior is prevented and monitored, and the reliability of power supply is improved.

Description

technical field [0001] The invention relates to a method for judging abnormal power consumption based on abnormal analysis of electric quantity, voltage and current. Background technique [0002] With the rapid development of urban construction, the demand for electricity in various industries continues to expand. However, with the rapid development of the economy and the continuous increase of electricity consumption, the problem of electricity theft has become more and more prominent. The power behavior is more concealed, causing serious power loss for power supply companies. The problem of stealing electricity not only affects the normal order of power supply and consumption of electric power enterprises, but also seriously affects economic development and social stability. Therefore, only by better improving the level of anti-stealing technology, completely plugging the loopholes of stealing electricity, and creating a good order of power supply and consumption, can we...
