Kalman Filter Approach for Line Parameter Estimation for Long Transmission Lines

Abstract

Transmission line parameters including series resistance, series reactance, and shunt susceptance are essential inputs to a variety of power system applications. The purpose of the study is to develop new methods to estimate line parameters for long transmission lines with different configurations under the effect of measurement noises by utilizing the Kalman filter techniques. Simulations are performed to demonstrate the effectiveness of the proposed methods. Results evince promising applications of the proposed new method.
