The following python code will check the Q-limit state of a machine:

def maclimits(ibus,id):
ierr, q    = psspy.macdat(ibus, id, 'Q')
ierr, qmax = psspy.macdat(ibus, id, 'QMAX')
ierr, qmin = psspy.macdat(ibus, id, 'QMIN')

answer = 0              #machine is within reactive limits
if   q >= qmax:
     answer = 1     #machine hits upper reactive limit
elif q <= qmin:
     answer = -1    #machine hits lower reactive limit
return answer           

#usage, having savnw loaded in PSSe:
qlimit = maclimits(3018,'1')
print qlimit
