Therefore, the stable operational region of generators is discussed along with the analysis on relationship between under-excitation operation and loss of excitation/synchronism, end temperature rise of stator-core,and automatic excitation regulators etc.

• 针对这种情况，对发电机稳定运行区域进行了探讨，并对进相运行与失磁失步、进相运行与定子铁心端部过热、进相运行与自动励磁调节器等关系作了分析。
