3 J+ Z- } H, l& `9 \! S: b "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 o% i0 S Y: v! C5 |' K

"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.

"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.

" J; k4 V% K9 G0 d, H"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.

Most popular stability analysis software should be able to provide these analysis for you. For theoretical understanding, I would recommend you to read page 133 of professor Ni-Yi-Xin's book "Dynamic Power System Theory and Analysis" which could be found here:
