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

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"
