we are analysing asymmetrical fault on PSSE, so we need to know during single line to ground fault and line to line fault which phases are considered faulty?

For the time domain dynamic analysis, psse can only simulate the symmetrical fault. In the short circuit analyses, we'll get only the short circuit currents of different faults. i.e. single Phase earth failure: the results are same if we have phase a, b or c failure.
