摘　　要：由发电机Ｐａｒｋ方程式推导出发电机定子电量与功角的关系，并由仿真计算验证了该关系式，从而得到一种新的发电机失磁定子判据，给出了新判据的流程图，并通过动模实验数据验证了该判据的有效性．The relationship between the rotor angle and the electrical quantities of generator stator is educed from Park equations. A new method to distinguish the loss of excitation of generator using the electrical quantities is presented. The correctness of this method is proved by the simulation and the experiment.
