An On-Line Measurement Method of Zero-Sequence Parameters of Double-Line on the Same Tower Based on WAMS

Estimation of zero sequence parameters of mutually coupled transmission lines from synchrophasor measurements

“…They report an error rate of 3% and less. In [9], the authors propose an online measurement method of zero sequence parameters of double line on the same tower. This method derives the closed‐form equations of the distributed line parameters (propagation constants and characteristic impedances) from the synchrophasor current and voltage measurements at the ends of the line.…”
