Abstract

In order to decide the insulation level of the equipment in converter station of ± 30 k V flexible low voltage DC transmission project reasonably and configure the lightning arresters

based on ± 30 k V flexible DC project of Dali photovoltaic boost in Yunnan

the transient overvoltage of converter station is calculated with PSCAD/EMTDC. According to the calculation results

the insulation coordination is studied. The research results have a significance on guiding the type selection and manufacturing of converter station equipment

and also provide a reference for the construction of flexible low voltage direct transmission project.
