摘 要: 基于特高壓換流站的特殊性考慮,介紹了兩種不同的避雷器配置方案,方案A 采用M2避雷器和CB1A 避雷器,方案B 采用A2 避雷器、CB1A 和CB1B 避雷器。討論了配置C2 避雷器的必要性,分析了CB1B 避雷器優(yōu)化經(jīng)濟(jì)性的原因及平抗分置所帶來的優(yōu)勢,并根據(jù)避雷器直流參考電壓的選擇原則選擇了相應(yīng)參數(shù),對DC 輸電工程具有參考作用。

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
