Abstract: In order to solve the problem of poor accuracy, low efficiency, and high consumption of human resources in abnormal power consumption of power distribution network, this paper used data mining technology to accurately locate abnormal power consumption data in magnanimity power utilization data. The network users who might have non-technical loss (NTL) were analyzed and detected by using the industry's seasonal power consumption level of the community's habits and other abnormal classification indicators. The improved particle swarm LM neural network optimization algorithm was utilized to establishe an effective automatic recognition model for abnormal power consumption. The experimental results show that this model can effectively extract the electricity characteristics and realize the detection of abnormal users with strong recognition ability and high practicability.
Key words: abnormal power consumption; non-technical loss; community feature; improved particle swarm optimization
