逐步增加发电机出力，，直至失稳，，

In my opinion, steady state stability limit is closely related to rescheduling mode. Given a rescheduling mode, or specifically provided a pair of increasing generation and increasing load, the power system reaches steady state stability limit consequently when it becomes small signal unstable.

It is acceptable that the small signal stability of a power system is approximately assessed in qualitative way by simulating its transient response to relatively small disturbance.

实际大网计算时好像增加发电机出力，然后做一单瞬故障校核，再根据确定的静稳裕度计算。

增加哪一台发电机的出力？
失稳的时候各个断面的潮流就是该断面的稳定极限吗？
如果运行方式发生改变呢？
