Transmission line parameters are inputs to various power system analysis algorithms and precision of these parameters are thus important in ensuring the analysis accuracy. This paper proposes methods for estimating positive-sequence line parameters of series compensated lines. Voltages and currents from two ends of the line are utilized. In addition, algorithms for estimating parameters of non-compensated parallel lines utilizing one end data for special scenarios are presented.
