The Station Area Recognition of Distribution Network Based on Electricity Information Acquisition System
In the electric energy data acquire system, the correctness of the archives in the station area is very important for the maintenance of distribution network equipment and the calculation of line loss. The existing equipment of station identification needs to identify the electric energy meters in a single station area one by one on the spot, and the workload is heavy on the spot. This paper analyses the parallel electric structure of the electric energy meter located in the same area in terms of electrical physical relationship. The variation law of node voltage collected by electric energy meter in the same area should have high consistency. On the other hand, according to the knowledge of circuit theory, the node voltage nearest to the transformer in the same area will be higher than that farther away from the transformer. Based on these two criteria, this paper quantifies the correlation between electric energy meters by calculating Pearson coefficient and compares the node voltage in the same area, so as to realize on-line identification of information in distribution network. Through an example analysis, the proposed method can accurately identify the accuracy of distribution network archives.
