| 摘 要： | 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。

| Abstract: | 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 . |
