A Low-Voltage Stealing User Location Method Based on Local Outlier Factor

Abstract

The invention relates to the technical field of anti-stealing power in low-voltage station areas, and proposes a low-voltage power-stealing user positioning method based on local outlier factors. First, based on the characteristic attributes affecting the line loss of the station area, search for the k stations that are most similar to the monitoring station area, that is, the k nearest neighbors; then, analyze the line loss of the monitoring station area based on the line loss rate of the k nearest neighbors. Whether the loss rate is abnormal; if the line loss rate is abnormal in a certain period of time in the monitoring station area, calculate the discrete Fréchet distance between the load curves of all users in the monitoring station area at that time; finally, calculate the monitoring station based on the Fréchet distance between the user load curves The local outlier factor of each user load curve in the area, the greater the local outlier factor, the greater the probability of stealing electricity. This method outputs the order of electricity stealing probabilities of all users in the monitoring station area with abnormal line loss rate, and only needs to detect the top users to detect most electricity stealing users, which greatly improves the efficiency of anti-electricity stealing.

Description

Technical field[0001]The present invention relates to the field of anti-relief technology in low pressure table, and more particularly to a low pressure stealing user positioning method based on a localized dispensing point factor.[0002]technical background[0003]With the improvement of social and economic development and residents' living standards, the demand for users is continuously enhanced, and the electricity spending is getting higher and higher, and there is a surge in electricity. The stealing capacity not only breaks the economic order and fairness of the electricity market, but also affects the safety and stability of the grid. In the past few years, with the comprehensive promotion of smart meters and electricity information collection systems, it has accumulated a massive user electricity data, how to use these data to more efficiently steal electrical detection, with important practical significance.[0004]Patent Open No. CN201410041012.9 is disclosed, which is disclose...
