Abstract

Based on the background of the Nuozhadu-Guangdong ±800 kV ultra high voltage direct current power transmission system

the insulation coordination of converter station is researched. On the basis of analysis on all kinds of overvoltage

according to the converter station insulation coordination principle of high voltage direct current power transmission

arrester configuration scheme and insulation level of converter station are proposed. At the same time

according to the converter station equipment switching impulse withstand voltage

the converter station valve hall air clearance is calculated. The research results of this paper may provide reference for design and construction of the direct current power transmission system in the future.
