Abstract

With the reliability requirements raising of VSC-HVDC technology

MMC sub-module reliability is more and more important.For high voltage electrical equipment

such as

VSC-HVDC converter valve

in order to ensure the safety and stability operation of equipment

the impact of electrodynamic force on the busbar must be considered.This paper provides a common check method of busbar design

and gives a simulation and analysis of one fault condition-when the upper IGBT is shorted in the MMC sub-module

then bypass switch is closed to cut off sub-module

and offers some optimization recommendations.Finally

the paper gives a simulation of improved case

to verify the rationality and effectiveness of the proposed recommendation.
