Identification of Low-voltage User Meter Box Combined with Known Phase and Address Information
Unclear mapping relationship between the user meters and the meter boxes
which may lead to serious consequences. Therefore
the identification of the meter box of the user meters is one of the metering topology identification problems of low-voltage distribution network. Since the entry lines of user meters in the same meter box share the same distribution box bus
if the total number
N
of the equivalent single-phase meter is known
the original problem can be converted into an
N
-classification problem based on the voltage sequential waveforms. Based on the analysis of the shortcomings of such method in practical engineering applications
an identification method of the low-voltage power distribution meter box combining the known phase and address information is proposed. First
the clustering method is used to identify the phase-separated voltage sequential waveforms to the distribution box level. Then
the mined and complemented address text information is applied to construct constraints based on neighborhood relations
and the constrained
k
-medoids clustering algorithm is used to divide users into the meter box level. Finally
two low-voltage distribution network cases with typical characteristics are used to verify the effectiveness of the proposed method.
