Hi all,

Please help me to get Mbase (MVA) of Machine from PSSE for Python.

I would like to use this to calculate with inertia (H) value.

Although I can get H as syntax below, I dont know how to get Mbase (MVA).

ierr = psspy.rwdy(option1=2,option2=0,out=0,ofile="C:\Program Files (x86)\PTI\PSSE34\EXAMPLE\python_test1.out")

21421 'GENROU' 1     11.000      0.47000E-01  0.67000      0.50000E-01
          6.2300       0.0000       2.1000       1.5500      0.21000
         0.40000      0.16000      0.13000      0.36100      0.69300

Thanks!

[For a working code to calculate inertia of entire power system, check my post "Inertia of a Power System"]

Use the following API function [chapter 7]:

ibus = 2141
id = '1'
ierr, mbase = psspy.macdat(ibus, id, 'MBASE')

Thank you for your support. I used your code, I can get data. If I need to get power from all these machines, please give me some advice. I tried to use for loop, in my opinion, this is not the best way.

A"for loop" should work OK. The API manual is part of the documents, installed at "C:\Program Files (x86)\PTI\PSSE33". Search Chap. 7 or other for the python functions you need for your project.
