"热稳极限" is a kind of conductor property. You should be able to find it from conductor manuals. Try to not exceeding a conductor's "热稳极限" by running a normal power flow analysis and any other contingency analysis. In simple, don't burn your conductor.4 J, J B1 B- C" j

"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. 0 ^7 C( \: H6 K+ i

"动稳极限", similar to "静稳极限", with control devices like exciter modeled. Both "静稳极限" and "动稳极限" apply to small disturbance.

"暂稳极限" is used to make sure the system will come back to previous stable state or changed stable state after a big disturbance like a fault, generator disconnection, reclosing. It needs a real time simulation and it is not possible for an on-line analysis software to provide such analysis currently.
