大型发电机定子中性点接地暂态仿真

The transient state emulate of large generator stator neutral grounding schemes

目前对大型发电机定子中性点接地方式的选择尚有争论 ,对研究方法及模型的建立尚有不足 .采用不同的单元电路形式 ,不同的单元电路串联个数 ,不同的定子绕组电感组成的准分布参数电路 ,利用PSPICE对大型发电机中性点电感接地方式进行了更为详细的仿真研究 。

The selection of large generator neutral grounding schemes is controversial,and the study method and model in this area need improvement to obain more accurate result,with the aid of PSPICE,the neutral resonant grounding schemes of large generator was analyzed through simulation.In order to get a exact result,the distributed parameter model was based on different pattern and series connection number of cell circuit,different inductance of stator winding and analyzed for result.
