I run this funtion:

ierr, rarray = psspy.awndreal(sid=0, owner=1, ties=3, flag=3, entry=1, string=['PCTRATEA'])

I get a numpy array with a number of values that is equal to 3 times the number of transformers that I have, one for each winding.

I do not understand the order of the results I get, not if it is sorted in ascending order, taking into account the bus number of the first winding, or if it is sorted by transformer name, etc.

Could someone explain to me how this function presents its results?

I'm working with 35.5.2 version.

Option ENTRY defines the order. 1 = winding 1 bus #, 2 = transformer name.

Use awndint to get the bus numbers and winding number.

An example:

ierr, iarray = psspy.awndint(-1,owner=1, ties=3, flag=3, entry=1, string=['WIND1NUMBER', 'WIND2NUMBER', 'WIND3NUMBER', 'WNDNUM'])
ierr, rarray = psspy.awndreal(-1, owner=1, ties=3, flag=3, entry=1, string=['PCTRATEA'])

data = iarray + rarray

for ibus, jbus, kbus, wind, pcta in zip(*data):
    print(ibus, jbus, kbus, wind, pcta)
