大型发电机定子绕组冲击电压分布

Surge Voltage Distribution in the Stator Winding of the Large Turbine-Generator

首次提出了大型发电机定子绕组的高频和低频暂态模型；提出了测量管态模型参数的方法，并实测了模型中参数的频率特性；模拟并实测了电机定子绕组冲击过电压分布及其波形；最后用EMTP程序计算了电机定子绕组的过电压分布及其波形．实测结果和计算结果非常吻合．

This paper givcs the fast and slow transient models of the stator winding of large turbine-generator, describes a method of measuring of the paramcters of the stator winding and measures those parameters in response to frequency. The voltage distribution and waves among stator winding exposed to surger voltage were analogized, measured and calculated (us ing the EMTP). The corrclation betweem the calculated results and the measured results is very good.
