I am building automation for running PSS/e from a Python program. I can call the psspy.runrspnsfile(rspname) to run a response file. I have not found nor figured out how to run a .py file from the automation. Does anyone know how to pass a python change file?
You can use the function 'execfile' to call a second python from a primary one. If psspy is used in the second python file, it will have to be imported explicitly. calling a second.py:
execfile(second.py,globals(),locals()) #globals and local can be omitted
All variables available in primary.py will be made available also to second.py!!
Now, at the beginning of second.py:
sys.path.append(r'C:\Program Files (x86)\PTI\PSSE33\PSSBIN') # psse\bin path where psspy is located
import psspy
#psspy.psseinit(80000) #only if psse was not started
_i = psspy.getdefaultint()
_f = psspy.getdefaultreal()
_s = psspy.getdefaultchar()
Follow-up question to the execfile(). In my second.py, let's say I'm using the API for psspy.bus_data_2() and I have some data that I want to use the default data (i.e. _i, _f). I'm getting the NameError that '_i' and '_f' are not defined. What's my work around to get this data to set to defaults?
