Abstract: This paper introduced two different types of arrester protection schemes based on the special consideration of ultra high vacuum (UHV) direct current (DC) converter station. The scheme A used M2 and CB1A type arresters and the scheme B used A2,CB1A and CB1B type arresters. This paper discussed the allocation necessity of C2 type arrester, analyzing the reason why CB1B type arrester could optimize the economical efficiency and the superiority caused by smoothing reactor distribution. According to the selection principle of arrester DC reference voltage, the corresponding parameters were selected, which provides references for DC transmission project.
Key words: converter station; arrester; over-voltage; smooth reactor
