摘要/Abstract

摘要： 采用架空输电线路分布参数模型及电压电流传播方程,考虑柔性直流系统阀侧的工频等值电路,建立了交流输电线路对柔性直流线路的工频电磁影响模型及连接变压器阀侧直流偏磁电流模型。最后以±160 kV柔性直流线路及110 kV交流输电线路参数为基础,分析了平行长度、平行距离、交流换位、直流换位等因素对偏磁电流的影响。

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
