摘　　要：本文简要介绍了Canny分析凸极同步电机模型参数的计算公式．计算出大型水轮发电机的模型参数，用来进行单相接地电容电流的数字仿真，并与解析计算的结果进行比较，两者计算的波形和数值均十分吻合。计算结果作为长江三峡发电机中性点接地保护的参考（本文在三块发电机参数提供之前暂用二滩550MW水轮发电机参数代替。）。Study on model parameters of salientpole synchronous generator proposed by Canay is introduced in brief The model parameters of 550MW salient-pole generator in the Er Tan power station are calculatcd. Single-phase toground fault is simulated. The result of simulation is very close to the analytical solution. It is used as a reference for generator neutral protection of the three Gorges Project.
