Abstract

Abstract: Aiming at the problem of poor identification of the line parameters in distribution network, this paper presents a method for identifying the line parameters in low-voltage (LV) distribution network based on advanced meter infrastructure (AMI). Starting from the nodes at the end of the network, the method estimates the branch line parameters of the network using the AMI measurement data. Nonlinear equations of the impedance parameters of the LV distribution line are established and the least square method is employed to solve the equations. In this way, the impedance parameter of all observable lines of the whole network can be identified and estimated. A case study has verified the feasibility and reliability of the proposed method.

Key words: advanced meter infrastructure, low-voltage distribution network, identification of line parameters, the least square method
