Abstract

A system simulation model is built with the device parameters from the Xiangjiaba-Shanghai HVDC Transmission Demonstration Project.The over-voltage generation mechanism and its distribution induced by three typical open circuit faults

i.e.the power absence of inverter substation

the open circuit of neutral line

and the open circuit of metal loop

are analyzed with the model.Moreover

aiming at the delay of protecting start-up and the operation delay of rapid grounding switch

a control method of over-voltage is presented.This study may be of help to the optimization of arresters layout for the following HVDC project.
