Abstract

Abstract: A model of power frequency electromagnetic impact of AC transmission lines on the parallel VSC-HVDC transmission lines and a DC bias current model on the converter transformer side are constructed by using the distributed parameters model of overhead transmission line and the voltage-current transport equation with consideration of the power frequency equivalent circuit on the side of DC system valve. In the end, based on the parameters of existing ±160 kV VSC-HVDC Transmission Lines and 110 kV AC Transmission Lines, the impacts of such factors as parallel distance, parallel length, AC transposition and DC transposition on bias current are analyzed.

Key words: VSC-HVDC transmission line, AC transmission line in parallel with DC transmission line, electromagnetic induction, DC bias current
