Abnormal electricity consumption judging method based on abnormal voltage analysis

Abstract

The invention discloses an abnormal electricity consumption judging method based on abnormal voltage analysis. The method comprises voltage phase-loss abnormity analysis, voltage threshold-crossing abnormity analysis and voltage imbalance abnormity analysis. The phase voltages of three or more monitoring points are monitored within one day for voltage phase-loss abnormity analysis, the voltage threshold-crossing abnormity analysis and the voltage imbalance abnormity analysis and are monitored for three continuous days; if the analysis results of the monitoring points in the three continuous days are confirmed to be abnormal, the users are confirmed as the abnormal electricity consumption users. The abnormal electricity consumption judging method based on abnormal voltage analysis 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 power consumption based on abnormal voltage 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 developme...

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
