This paper analyzed and summarized characteristics of over voltage protection in ±800 kV ultra high voltage direct current each pole had two 400 kV 12 pulse converter in series
and compared with that of ±500 kV HVDC convert station.Meanwhile
instancing practical UHVDC project
typical fault status were selected
simple simulated calculations of switching impulse over voltage were performed to several key spot in convert station under the condition of arrester’s protection.The results provided the references to protection level of main arrester
and to the withstand voltage level of facility in UHVDC convert station.
