低压用户窃电导致线损电量增加,对台区线损异动进行归因分析是识别窃电用户的有效途径。低压用户通信异常多发,可导致用电信息采集系统主站数据失真,易误导窃电检测。利用配变终端可就地完整准确采集台区数据的特点,提出基于边缘计算的低压用户窃电检测方法。首先,在通信正常和异常的条件下,分析台区窃电用户用电量与线损电量的关联关系;然后,在配变终端窃电检测模块中对真实的台区线损和用户用电量进行归因分析来识别窃电用户;最后,基于高损台区实际数据的仿真分析,验证了所提方法相比于在主站侧采用异常数据以及采用不同缺失数据填补算法修复后的数据进行窃电检测时的优势。
Electricity theft of low-voltage users increases the line loss power. It is an effective way to identify the electricity theft users by the attribution analysis of line loss variation in distribution area. The frequent communication anomaly of low-voltage users may lead to the distortion of the data in the main station of the electricity information acquisition system
which tends to mislead the electricity theft detection. Using the characteristic that the distribution transformer terminal can collect the distribution area data completely and accurately
an electricity theft detection method for low-voltage users based on edge computing is proposed. Firstly
the correlation between electricity consumption and line loss power of electricity theft users in distribution area is analyzed under normal and abnormal communication conditions. Then
the attribution analysis is carried out on the line loss power and electricity consumption in the real distribution of the electricity theft detection module in distribution transformer terminal to identify electricity theft users. Finally
based on the simulation analysis of the actual data in the high-loss distribution area
the advantages of the proposed method compared with electricity theft detection using the abnormal data on the main station side and the data restored by different missing data filling algorithms are verified.
