Embodiment Construction
[0042] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.
[0043] The present invention is a method for detecting electricity stealing in a line based on wavelet analysis of electric power data, and the implementation process is as follows: figure 1 , the steps include: calculating the hourly output power of the distribution station area and the hourly power consumption of each user according to the power data; wherein the power data includes the hourly electricity consumption of the total watt-hour meter of the distribution station area and the watt-hour meter of each user Hourly power consumption; according to the calculated hourly power, calculate the hourly line loss rate curve of the line; standardize the line loss rate curve. Perform local wavelet transform with a sliding window on the standardized hourly line loss rate curve, and extract the singular value vector after wavelet transform; calculate the ei...
