Abstract
The low voltage station area is directly connected to the user,and the number is huge.At present,it is difficult to determine the cause of line loss in the low voltage station area due to complex wiring,lack of topology,lack of measurement points of intermediate nodes and other problems.A method based on topology recognition to analyze the cause of line loss in low voltage station area is proposed.The identification results of the variable relationship are used to determine whether there is the influence of the variable relationship error.The consumer phase connectivity is employed to determine whether there is three-phase unbalance and the influence of the main line problem.The user link relationship is used to identify the results,determine whether there are branch line problems and user power theft problems,and can locate the branch line that may have problems.The method proposed only needs the voltage,current and power data of the measuring points in the low-voltage station area,and uses the low-voltage topological connection relationship to deduce the cause of the line loss problem layer by layer.The line loss problem is refined to the branch line between the user and the user,so as to achieve accurate problem positioning and effectively reduce the maintenance workload of operation and maintenance personnel.关键词
