This method can understand the line loss of the entire station area to a certain extent, but when the line loss is abnormal, it cannot automatically determine the abnormality of the line loss
[0003] Most of the methods for line loss analysis in the prior art refer to the big dataanalysis method of unsupervised learning to realize the line loss analysis of the station area. The advantage is that it is more intelligent and automatic than the existing actual solution, but it can only Analyze the total line loss in the station area, and the accuracy is not good

Abstract
The invention discloses a transformer area line lossanalysis method, device and system. The method comprises the following steps: acquiring a line loss training sample set with labels; acquiring a line loss set without labels; calculating the Euclidean distance between the line loss of each user without labels and each piece of data in the line loss training sample set, and sorting all obtained Euclidean distances; for each user, respectively selecting first k Euclidean distances, and calculating a corresponding Euclidean weight distance; for the classifications related to the k Euclidean distances, calculating Euclidean distance weight sums corresponding to the classifications; and taking the classification label with the maximum Euclidean distance weight sum as the classification of the line loss data without the label. According to the invention, the artificial intelligencealgorithm is used to effectively analyze the line loss condition of the users in the power distribution area, so that fine management of the power distribution area is facilitated.
Description
technical field [0001] The invention belongs to the technical field of line loss analysis in a station area, and in particular relates to a line loss analysis method, device and system in a station area. Background technique [0002] The line loss of the distribution station area is very important. It is the basis for the fine management of the station area. line loss calculation. The calculation method of the line loss in the station area is the total input power of the distribution transformer in the station area minus the total input power of each user, and the difference is the line loss in the station area. The difference divided by the input power of the transformer in the distribution station area is the total loss rate of the station area. This method can understand the line loss of the entire station area to a certain extent, but when the line loss is abnormal, it cannot automatically determine the abnormality of the line loss. [0003] Most of the methods for li...
