The invention discloses a low-
voltage distribution area wire user identification method and
system based on an improved clustering
algorithm, and belongs to the field of low-
voltage distribution area wire user identification. According to the method, multi-dimensional information such as
voltage amplitude
time sequence data,
current time sequence data, phase sequence information of each user, primary
branch feeder data and the like of a low-voltage
bus and each user electric meter in a low-voltage distribution area is comprehensively considered, so that the limitation of dependence on single voltage data is overcome; using an
Euclidean distance algorithm to screen and identify head-
end user electricity meters, and eliminating the interference of the head-end
electricity meters on clustering; the characteristic that the DTW distance
algorithm can better process the similarity measurement of the
time sequence data is utilized, and the DTW distance algorithm and the clustering algorithm are combined, so that the recognition accuracy is improved; and finally, line user identification is carried out from a global angle, so that the accuracy of line user identification in the low-voltage distribution area is improved, and the problem of low accuracy of line user identification in the low-voltage distribution area caused by dependence on single data and
neglect of interference of a head-end
ammeter in the prior art is solved.
