"静稳极限" could be calculated by ignoring any dynamic models like exiter, governor, stabilizer, etc. Typically this value could be calculated without doing a real time simulation and then it could be provided by an on-line analysis software.

It needs a real time simulation and it is not possible for an on-line analysis software to provide such analysis currently. 0 u4 ?1 i D$ G" Y
