"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.

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:
