Estimation of parameters for faulted transposed transmission lines

Kalman filter based method for tracking dynamic transmission line parameters

“…Different online methods have been proposed in [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] to estimate line parameters considering the line length, specific line configurations, data availability, etc. The methods for estimating zero-sequence line parameters are proposed in [11][12][13].…”

“…The method treats parameters as constant during a time window. In [20], the author proposed a method based on the Clarke's transformation matrix using faulted voltage and current measurements obtained at the line terminals. The authors of [21] proposed a method for estimating line parameters using data during a grounding fault.…”
