| description |
Aiming at the problems of high cost and low efficiency of manual calibration of low-voltage distribution network topology , a topology identification method of low-voltage distribution network based on GIS and voltage waveform correlation analysis is proposed. Firstly , according to the geographic information of the distribution and user in the GIS platform , combined with the spatial constraints of the household variable relationship , the overlapping areas and non-overlapping areas are screened out , and the household variable relationship of the non-overlapping areas is preliminarily determined. Secondly , the voltage sequence correlation between the user in the overlapping area and the distribution in the adjacent station area is analyzed , and the three indicators of Euclidean distance , DDTW and Pearson correlation coefficient are used to evaluate the household change relationship in the overlapping area. Finally , the voltage correlation trend of the overlapping area is continuously monitored dynamically , and when the voltage correlation between the user and the station area changes drastically , the voltage correlation of the user and the adjacent station area is recalculated , the station area to which the user belongs is determined , and the alarm information is pushed to the operation and maintenance personnel for manual verification and confirmation. A numerical example shows the effectiveness and feasibility of the proposed method. |
