Abstract

On the basis of classical theoretical analysis of transmission line parameters, a simulation model of dual circuit four split 500kV transmission line is constructed. When the parallel length ratio of the double circuit line varies from 10% to 100%, and the non-measurement line is grounded at both ends, Obtain the variation pattern of the zero-sequence impedance of the measured line, and obtained the general range of magnetic effects under the conditions of parallel operation of two single circuit lines. In addition, taking actual transmission lines as examples, the applicability of the model to conventional transmission line parameters is demonstrated, which has a certain guiding role for practical engineering.
