Research on Line Loss of Low-Voltage Substation Based on Smart Electric Meter Clustering Algorithm

Abstract

At present, electric power company judgment on abnormal line loss is that the line loss is abnormal when the line loss rate exceeds a certain threshold. Yet the judgement is one-sidedness and limited.Aiming at the large proportion of low-voltage distribution network loss in the total loss of power grid, this paper introduces the line loss analysis process, constructs the line loss analysis model based on smart electric meter the four dimensional eigenvalues of daily average line loss rate, line loss rate variation coefficient, three-phase imbalance, power factor abnormality, and puts forward a method of identifying line loss abnormality in low-voltage distribution network based on clustering algorithm. The experimental results show that the method has certain practical application effects, which can accurately analyze the line loss rate and improve the accuracy of line loss anomaly judgment.
