Revision history [back]

Hi friends,

I am trying to define a subsystem consisting of two areas, numbered in PSS/E as 19 and 20.

This is my code:

ierr = psspy.asys(4, 2, [19,20])

print ierr

where 4 is the desired subsystem number.

ierr comes out as 0, but the actual subsystem is EMPTY !!

I have used bsys before (which is more complicated), but haven't been able to make asys work,

Please, help !

Thanks a lot,

Andre

P.S. Have just found out this forum, very useful, thanks !

This is my code:

ierr = psspy.asys(4, 2, [19,20])psspy.asys(subsystemnumber, numberofareasto_set, areas)

print ierr

where 4 is ierr, areas = psspy.aareacount(subsystem_number, _i)

print areas

print ierr

ierr, numbers = psspy.abusint(subsystem_number, _i,"NUMBER")

print numbers

On the desired subsystem number.

ierr screen, I get:

0

0

[None]

Please, does anyone know why my numbers array comes out as 0, but the actual subsystem is EMPTY !!

Please, help !empty ??!!

This is my code:

areas = [19,20] ## these areas DO existexist

ierr = psspy.asys(subsystemnumber, numberofareasto_set, areas)psspy.asys(subsystem_number, number_of_areas_to_set, areas)
