风电场升压站中性点接地方式选择，主要是考虑有效地限制弧光接地过电压，消除谐振过电压，能够快速准确判断故障。选择小电阻接地方式能够满足该要求，但没有规范对小电阻选择进行规定，这里仅对小电阻的特点进行分析，并对实例进行了探讨。

In the selection of neutral grounding mode in booster station of wind power station , considerations are mainly focused on the effective restriction of arc grounding overvoltage , elimination of various resonance overvoltage , and con-venience for quick and accurate judgment of malfunctions .These requirements can be met by the low resistance ground-ing mode.However, no specification is available for the selection of such low resistance .Characteristics of the low re-sistance mode are analyzed and practical examples are discussed .
