摘要

A new measurement method of the multiple-circuit transmission lines' power frequency impedance parameters on the same.tower is proposed in this paper based on the assumption of the threephase unbalance and induced voltage is constant in a short time. By applying a single-phase AC supply and multiple measurements, the mathematical model of the double-circuit transmission lines' power frequency impedance parameters based on the measured voltage and current is established, and then the sequence impedances and sequence coupled impedances can be resolved. This method is simple, accurate and without the influence of three-phase unbalance on the measurement of transmission line parameters. The simulation results show the validity of the proposed method.
