I used the code below to get a list of FACTS device names (not dynamic model names). How can I retrieve the bus # for each loadflow model?
ierr = psspy.inifax()
ierr, nextfax = psspy.nxtfax()
while ierr ==0:
ierr, nextfax = psspy.nxtfax()
print nextfax
return #exit out of the script
Why not just the subsystem data retrieval APIs? Check chapter 8 of the API manual. It is either the "aFactsInt" or "aFactsBusInt" API.
I ended up using a loop. It cycles through all FACTS devices to match a bus # to the name but there are ~ 10 in the case so it is quick. Inelegant escape from the way it exits: either return the bus # or just "not found"
def getname(busnum):
ierr = psspy.inifax()
ierr, nextfax = psspy.nxtfax()
nextbus = ""
while ierr ==0:
ierr, nextbus = psspy.fcdint_2(nextfax, 'SEND')
if nextbus == busnum:
#print "found it " + str(nextfax)
return str(nextfax)
else:
ierr, nextfax = psspy.nxtfax()
return "notfound"
