Hi!
How do I copy the complete network data from a particular zone in NETA.sav to NETB.sav?
I remember using RAWD in the past. Here is how you might do this:
psspy.case('NETA.sav')
export_zones = [1]
psspy.bsys(sid=1, numzone=len(export_zones), zones=export_zones)
psspy.rawd_2(sid=1,
all=0,
status7=2, # create a RDCH file
out=0, # redirect to file
ofile='my-zone-1.raw')That should create your "Power Flow Change Raw Data" file. The next main step is to read it in for NETB.sav
psspy.case('NETB.sav')
psspy.rdch(ifile='my-zone-1.raw')I'm not sure what other problems will pop up. Here is a couple you might need to watch for:
What's the easiest way to duplicate certain network elements (e.g. add another transformer by copying an existing one in the basecase)?
Hi,
I am new in PSSE for Python. My question is... after reading the .raw file with RDCH, then what? How to print this information? Is this information stored in memory, I guess, so how to access to the information we have just read?
Greetings!
You'll have more success asking a new question rather than posting your question as an answer to someone else's question. Regardless, once you've used RDCH, the network will be in memory. You could save it as a separate SAV file for later (using save()).
Thank you!

You could create a "Power Flow Change Raw Data File" containing just the section from that particular zone. I can't see how to make one with the API - do you know how?
@JervisW I can't see how to do this with the API either. After a lot of reading and experimenting I found that the easiest way is to do it is through the PSSE GUI.
@amaity yes, I think the GUI would be quicker. It isn't often that we need to transfer data. Would the RAWD method work?
