First just to clarify, the LHVRT (or VTGTPAT in psse) its optional for wt3g2. To implement a windturbine you must have a WT3G2, WT3E, WT3T and WT3P. The others models are optional. you can see more info here psspy.org/psse-help-forum/question/2659/how-to-incorporate-lvrt-in-wind-machines-psse/

short answer, yes. I suggest this page, it helped me alot:link text

To extract data from .out files to excel datasheet I use this script in python: (simply copy the code between the lines made of '#' to a .py extension file and run it, you should change the path to pss/e bin path and should run it from the same folder of your .out file, alse change the variable "name" to the name of your .out (in this case the file was "x.out" ))

# # # # # # # # # # # # # # # # # # # # # # # # # # # # # #

import os,sys

sys.path.insert(0,'C:\Program Files (x86)\PTI\PSSEXplore33\PSSBIN')

os.environ['PATH'] = 'C:\Program Files (x86)\PTI\PSSEXplore33\PSSBIN'+';'+os.environ['PATH']

import excelpy

import dyntools

import time

name='x';

data=str(time.localtime().tmmday)+" do "+str(time.localtime().tmmon);

outfile = dyntools.CHNF(name+'.out')

shorttitle, chaniddict, chandatadict = outfile.getdata()

xlsfile=name+'.xlsx';

xl = excelpy.workbook(xlsfile, mode='w');

outfile.xlsout(sheet=name,overwritesheet=True);

xl.close();

xl.save();

xl.close();

Hi there

Unfortunately there is no way to reverse the process. Once you have converted the generators you cannot perform a power flow anymore. My advice to you is, from nowone, always maintain a copy of the files before the conversion of the generator/loads.
