| 摘 要： | 发电机中性点运行方式有中性点不接地、小阻抗接地、高阻抗接地、消弧线圈接地。不同的发电机中性点运行方式对不同的发电机定子接地保护方式的保护效果影响很大,其中的外部注入低频信号定子接地保护,能够适应各种不同中性点接地的发电机,不但能够反映定子绕组的接地故障,而且能够反映定子绕组回路对地绝缘降低,这是今后发电机定子接地保护的主要方法。

| Abstract: | Generator neutral ground methods include non-ground,low impedance ground,high impedance ground and arc-suppression coil ground.Different generator neutral point operating modes have significant impact on stator grounding protection effects.Extemally applied low frequency signal stator ground method,which accommodates generators with different types of grounding,can indicate the staor winding ground fault,as well as reduction of stator winding circuit insulation.It is the major way for stator ground protection in the future. |

| Keywords: | generator neutral ground method staor ground protection |
