How to output in a readable format the monitoring in PSS/E

I have this script:

CASE = r'''C:\\Program Files (x86)\\PTI\\PSSE34\\EXAMPLE\\savnw.sav'''
psspy.case(CASE)

# Convert loads (3 step process):
psspy.conl(-1,1,1)
psspy.conl(-1,1,2,[0,0],[100,0,0,100])
psspy.conl(-1,1,3)

# Convert generators:
psspy.cong()

# Solve for dynamics
psspy.ordr()
psspy.fact()
psspy.tysl()

# Add dynamics data
psspy.dyre_new(dyrefile="C:\\Program Files (x86)\\PTI\\PSSE34\\EXAMPLE\\savnw.dyr")

# Add channels by subsystem
#   BUS VOLTAGE
psspy.chsb(sid=0,all=1, status=[-1,-1,-1,1,13,0])

# Initialize
psspy.strt(outfile="test.out")   <----------------------------------------------
simtime = 1
#psspy.run(tpause=simtime)
psspy.run(0,simtime,99,19,0)

but turns out that the test.out file is in binary and hence, cannot be interpreted directly but just for PSS/E. I was wondering whether there is a way to output such content in a readable format, such as .csv, .xlxs,... to treat it. If not, could you come up with an idea to deal with this situation?

Thanks for your time.

Tomás.

Check the python code "dyntools_demo.py" located in the "example" folder, to extract (all or selected) channels in an *.out file. To get a description of the functions available in "dyntools.pyc", run the following code:

#display help in module dyntools.pyc
import psse33
import dyntools
help(dyntools)

You can export to Excel in the GUI:

  1. Open .out file
  2. Right click the file in Plot Tree View and select "Export to Excel"
  3. All channels are now written to a .xlsx file.

Unfortunately, there is no API to perform the action from python.

Thank you for replying. Unfortunately, that's not a valid solution for me. Do you know if there is a way to ask for the monitoring data through the python API?

You can open the .out file with dyntools and write the channel values to .csv or an excel file using for example excelpy.
