PSSe Fortran code cannot be used directly into PSCAD.

PSCAD is a 3-phase modeling tool with integration times in the microsecond range while PSSe is a positive-sequence, RMS-based modeling tool with integration step in the millisecond range. PSCAD uses mainly a GUI-based modeling approach similar to simulink (matlab) and Fortran code for those models not in their library while PSSE UDM development is mainly Fortran code based, unless the NEVA tool (GUI-based...) is used. The modeling assumptions would not be the same or compatible between these platforms.
