In PSSE Xplore 34 version, I've found that there is an example .ECD file given in the 'EXAMPLE'' folder (C:\Program Files (x86)\PTI\PSSEXplore34\EXAMPLE) named savnw.ecd. To import this into PSSE, I used the following code snippet:

opening .SAV file first

psspy.case(r"""C:\Program Files (x86)\PTI\PSSEXplore34\EXAMPLE\savnw.sav""")

solving for load flow

psspy.fnsl([0,0,0,1,1,1,0,0])

importing and running ECd for particular load (3285.6 MW) and MVA (100 MVA)

psspy.ecdi(0,1,1,r"""C:\Program Files (x86)\PTI\PSSEXplore34\EXAMPLE\savnw.ecd""",0,[0.0,0.0]) psspy.ecdi(0,1,2,r"""C:\Program Files (x86)\PTI\PSSEXplore34\EXAMPLE\savnw.ecd""",0,[0.0,0.0]) psspy.ecdi(0,1,3,r"""C:\Program Files (x86)\PTI\PSSEXplore34\EXAMPLE\savnw.ecd""",0,[ 3258.6, 100.0]) psspy.ecdi(0,1,4,r"""C:\Program Files (x86)\PTI\PSSEXplore34\EXAMPLE\savnw.ecd""",0,[0.0,0.0])
