Based on varying process of generator terminal parameters after excitation fault, shortages of excitation protective principle of static stability boundary and asynchronous impedance boundary are analyzed. It proposed that excitation fault research relates to large-disturbance stability. Because dynamic power-angle character of generator after excitation fault is non-sinusoidal, there are differences between dynamic power-angle character and static state power-angle character. So it isn't ideal to protective operation result based on small-disturbance stability and static stability boundary criterion. At the same time, it proposed that asynchronous boundary impedance criterion is a constant reactive power circle moving adown j Xd′. It can ensure complete loss-of-excitation generator measuring impedance enter into the circle, but can't ensure the other condition measuring impedance including impossible losing synchronism enter. So loss-of-excitation protection would be maloperation when system voltage drops short and recovers or generator rejects load.③Based on stability principle, it puts forward setting conditions and calculation method of generator loss-of-excitation protection by direct measuring power-angle.
以励磁故障后发电机端的相关参数的变化为基础,通过对以静稳定边界和异步阻抗边界作判据的两类三种现行励磁保护在原理上存在的缺陷分析,发现:励磁故障是一个大干扰稳定性问题,励磁故障后的发电机的动态功角特性与静态功角特性有很大的差异,已远非正弦曲线,因此基于小干扰稳定性原理、以静稳定边界作判据的保护必然动作不理想;异步边界阻抗判据是一个下移j Xd′的等无功阻抗圆,它可以保证完全失磁后的发电机测量阻抗能进入该阻抗圆,但不能保证完全失磁之外的其它状态不会进入该阻抗圆,因此在系统电压短时下降或发电机突然甩负荷等情况下可能启动该保护使之误动。
