Abstract: The current anti-stealing management mode is unable to meet the needs of anti-stealing management under the new situation, and data mining is a powerful tool to meet the needs. Based on the accumulated various data source systems from power companies, extracting information using data mining techniques to build an anti-stealing management system, which shares resources and supports decisions, is proposed in this paper. The system design, data processing, modeling and technological realization are introduced, and the offset-degree of line-loss, difference degree of electricity, imbalance of voltage and current as well as other aspects are analyzed.

Key words: power system, smart meters, data mining techniques, electricity anti-stealing, management system
