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

Embodiment Construction

[0021] see figure 1 , the abnormal power consumption judging method based on the abnormal power analysis of the present invention includes a fluctuating power analysis process and a zero power analysis process;

[0022] The fluctuating power analysis process includes: comparing and analyzing the historical power consumption of power users in normal operation, searching for a list of users whose power fluctuation ratio exceeds a predetermined fluctuation ratio according to the fluctuation direction, supplemented by various statistical conditions and screening conditions , the statistical conditions and screening conditions include parameters such as power quantity date, user attribute, line to which they belong, and substation to which they belong, and then analyze and give a list of users who may have abnormal power, and the staff will analyze and check the abnormal users; for abnormal users, specify a certain The electricity consumption in a certain month of the year is compa...

Abstract

The invention discloses an abnormal electricity consumption judging method based on analysis of abnormal electric quantity. The method comprises a fluctuating electric quantity analysis process and a zero electric quantity analysis process; the fluctuating electric quantity analysis process comprises the steps: analyzing and giving a user list with possible abnormal electric quantities; with respect to an user with abnormal electric quantity, appointing the electricity consumption in a certain period and comparing it with the specific historical electricity consumption of the user, calculating a fluctuation proportion and considering the user to be the abnormal electricity consumption user when the fluctuation proportion exceeds the expected fluctuation percentage value. The zero electric quantity analysis process comprises the steps: giving a list of electricity users, the daily electricity consumptions of which are zero and are abnormal electricity consumptions; analyzing and checking the abnormal users by work staff and confirming what users with abnormal electric quantities are true abnormal electricity consumption users. The abnormal electricity consumption judging method based on analysis of abnormal electric quantity has the advantages of immediately knowing power users' electricity consumption information, preventing and monitoring electricity stealing behaviors and improving power supplying reliability and the like.

Description

technical field [0001] The invention relates to a method for judging abnormal electricity consumption based on abnormal electricity analysis. 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 better escort the rapid...
