| 摘要: |
| 目前对大型发电机定子性点接地方式的选择尚争论，对研究方法及模型的建立尚有不足，为了不得到更准确的结果及探讨在接方式的选择上应注意的问题，采用准分子参数电路模型，利用ＰＳＰＩＣＥ对电阻和消绵线圈两种主要接地方式从不同角进行了垓 真研究，并两种接地方式 的优缺点进行了比较，指出基采用消弧圈与较小电阻串联的接地方式，不失为一种合知的选择。 |

| Abstract: |
| The selection of large generator neutral grounding schemes is controversial,and the study method and its modeling need improving to obtain more accurate result and find out the aspects to be paid attention to.Based on distributed parameter circuit model,the high resistance grounding scheme and resonant grounding scheme are investigated with PSPICE.The merits and shortcoming of both schemes are compared.The simulation results suggest that the resonant coil in series with a small resistance seems to be a suitable selection. |
