I am simulating a power system in PSCAD and getting following error
"EMTDC Runtime error
Abnormally termiinated"
If your simulation case does not die right away, reduce the simulation duration from T_end to 0.5*T_end. If it the same error occurs again, reduce it further to 0.25*T_end. If not, increase it to 0.75*T_end. The point is to find the longest simulation duration without causing the error. You can then plot the node voltages and see if any of them show problems, such as growing steadily in magnitudes, numerical oscillation. Once a node with problem is found, you can examine its neighboring components to find the root cause of the problems. Components that are likely to cause problems are saturation, switching devices(make sure you turn on interpolation if there are switching components in your system), pure inductive nodes.
Most of the times when I faced such an issue was when there are model issues in the PSCAD. Check if there are any electrical discontinuities, mismatched parameters etc.
