Awesome help.

I have a question:

I would like to do the same but insted of activating a project, i want to import a raw file (from psse) and then activate that project and perfom the simulation.

I cannot find a command for importing from raw. Any idea? How can i use commands for that purpose?

Thank you in advance

Do you have to import the raw model several times or just once? I found myself trying to make something with python that it is much easier by using digsilent interface.

Thank you very much for the fast response.

Doing it by using the digsilent interface is much easier, but the simulation is ran externally from a web application:

The application user upload a raw file
The application calls digsilent using Python
digsilent import the raw file, activate the Project and perform simulation
Digsilent return results and the web application shows information

I have everything working but the automation of that task. I can do it manually but makes no sense regarding the application objective.

Any suggestion Will be appreciated.

Alejandro

I have never made it. But maybe this can work: import sys, os import numpy as np sys.path.append(r"C:\Program Files\DIgSILENT\PowerFactory 2019 SP3\python") import powerfactory ## DigSILENT set up # start PowerFactory in engine mode app = powerfactory.GetApplication() # activate project project = app.ActivateProject("blank") # change "Nine Bus System" by the name of your project #prj = app.GetActiveProject() # active project instance psse = app.GetFromStudyCase("ComPsse") # Load flow psse.rawname = r'C:\Users\jmmau\OneDrive\Desktop\k13p2.raw' psse.Execute()

I have just added this line before the last one:

Awesome help. Thank you so much.

Hi Juan, thanks for posting this. I actually have a simular issue to one that was mentioned earlier in the thread, where i get an error: "AttributeError: 'NoneType' object has no attribute 'ActivateProject'". I have no idea why I am getting this error... I am using the demo version of the latest Powerfactory version... and wondering if maybe this demo doesnt provide access to the python api... hence I am being returned none...

Here is my code for starting powerfactory in engine mode:

"import sys
import os
sys.path.append(
r"C:\Program Files\DIgSILENT\PowerFactory 2020 SP1B\Python\3.8")
import powerfactory as pf

class PowerFactorySim(object):
def init(self, folder_name='', project_name='Project', study_case_name='Study Case'):
#start powerfactory
self.app = pf.GetApplication()
#activate project
self.project = self.app.ActivateProject(os.path.join(folder_name, project_name))
#activate study case
study_case_folder = self.app.GetProjectFolder('study')
study_case = study_case_folder.GetContents(
study_case_name+'.IntCase')[0]
self.study_case = study_case[0]
self.study_case.Activate"

And then the relevant part of a separate python file I have using to call this method is here:

"import csv
from pfsim import PowerFactorySim

FOLDER_NAME = ''
PROJECT_NAME = '14_bus_EMT.IntPrj'
STUDY_CASE_NAME = 'emt_test_case'
MONITORED_VARIABLES = {
# 'Gen_0008.ElmSym': ['s:phi', 's:speed', 's:fe'],
'*.ElmTerm': ['m:ul:A', 'm:ul:B', 'm:ul:C']
}

sim = PowerFactorySim(
folder_name=FOLDER_NAME,
project_name=PROJECT_NAME,
study_case_name=STUDY_CASE_NAME)"

If you could provide any pointers what so ever I would be so grateful... I am new to powerfactory and currently banging my head against the wall...

I have a question. I am using DigSILENT 15.1 and python 3.8. I am trying to run power factory both in engine mode and ComPython mode.
I am having trouble in interfacing both the applications.

When running in Compython , I cannot import numpy as np (powerfactory has an older version of python without pip)
When in engine mode , I receive this error :
Traceback (most recent call last):
File "<pyshell#2>", line 1, in
import powerfactory
ImportError: DLL load failed while importing powerfactory: The specified module could not be found.

This is my code 👍

import sys
sys.path.append(r"C:\Program Files (x86)\DIgSILENT\PowerFactory 15.1\python")
import powerfactory

Appreciate if I can get an advice and where I am doing wrong
Thank you

DigSilent 15.1 works only with python 3.3. I am currently working in it. However, i have question regarding performance of DigSilent 15.1 with python.
I have created script that run power flow with different conditions of power system. It's work however to retrieve the data it takes very long time (100x more time if i use DigSilent 2020) with same script. What does caused it?

I think it is possible from everywhere but using the power factory python. El vie., 13 sept. 2019 21:26, Johnaristidou ***@***.***> escribió:

Can I run this script through pycharm or anaconda or only in powerfactory? — You are receiving this because you authored the thread.

I am using PowerFactory 2020 SP3 (x64), Build 20.0.5.0 (10037) / Rev. 75304 and Python 3.8 on a Windows 10 lapot, installed in C:\python (which has been added to %PATH%).

I'm trying to run a very simple 'HelloWorld' script:

import sys

sys.path.append('C:\\Program Files\\DIgSILENT\\PowerFactory 2020 SP3\\Python\\3.8\\')

import powerfactory as pf

app = pf.GetApplication()
app.PrintPlain("Hello PowerFactory")

I have this code in file powerfactory_main.py. When, In PowerFactory, I add a Python Script (ComPython), point to to the file as External Python Script and hit Execute I get a nice Hello PowerFactory in the Outpput Window of PowerFactory. However, once I open the script in VS Code (v 1.63.2 -user setup), hit Run Python File in Terminal I get the aforementioned error:

AttributeError: 'NoneType' object has no attribute 'PrintPlain'

Does anyone have a clue what's going on here? I can't seem to get the solution from the comments above.

Question: does PowerFactory need to be running?
I see references to "engine mode", but I have no idea what that means.

Hi Everyone
I have a alot of loads with (parameter characteristic - vector (loads with time series every 15 min. for a time period one year )) in Excel file (.xlsx) and i need to import them using python script. can anbody help me out ???

Hi @Sarah3802 ,
I had created script, but to create Time Characteristics. I will try to convert it, but i don't know it will work or not

First you should get the characteristics folder and scale folder
fold_char = app.GetProjectFolder('chars')
fold_scale = app.GetDataFolder('IntScales')

and then you should create the time scale first by using this code :
time_scale = fold_scale.CreateObject('TriTime', 'time_scale_15_minute_year')
time_scale.unit = 3 #(It means hour per year)
time_scale.scale = [i/4 for i in range(0,24*365*4)]

and then for each loads 👍
for load in loads:
load_scale = fold_char.CreateObject('ChaVec', '{} MW'.format(load.GetAttribute('loc_name')))
load_scale.scale = time_scale #to refer the time scale that we created before
load_scale.vector = #YOUR LOAD CURVE (one dimension array)
load_link = load.CreateObject('ChaRef','plini') # plini refer to Active Power Load Parameter, you can change it as appropriate
load_link.typ_id = load_scale

I hope this help

Thank You so much Sir, its really helpfull, but i'm wondering how can i read data from excel file (.xlsx)?

Thank You so much Sir, its really helpfull, but i'm wondering how can i read data from excel file (.xlsx)?

Is it possible to save it as .csv instead?

As @SjorsHijgenaar , you can use CSV file or if you want easier, you can use pandas module

I've already converted it, but it looks messy

i would like to read data from excel using the module “pandas”, i found that i can use

import pandas as pd
pandas.read_excel('File_name','sheet name')

The data will then be returned into a DataFrame. The DataFrame has the advantage of providing easy access to columns and rows. But, i'm not able to map the header in the Excel file with a load object in PowerFactory, can someone help me here ?

the easiest one will be the column header has the same name with load name in PowerFactory. And then you can map it like this:
loads_data = app.GetRelevantObjects('*.ElmLod')
for load in loads_data:
try:
load_curve = df[load.GetAttribute('loc_name']
except:
print(f'load curve for {load.GetAttribute('loc_name']} not found') #catching error because load name is not in data

Is there a way to extract multiple parameters of all synchronous machines at a time and write to a csv file?

@midhunagarapati , what parameter do you want to extract? If it's just static parameter like inertia, time constant or etc, the easiest one is directly use GUI of powerfactory through Network Model Manager. Chose Generator, and then go through flexible tab.
You can define the parameter in there.

@rizky-r-lab I want to extract simulation RMS parameters like transient reactances and change them according to the size of the machine

i searched for a long time now to find all attributes a element can have. Is there a list i didnt know about?

the easiest one will be the column header has the same name with load name in PowerFactory. And then you can map it like this: loads_data = app.GetRelevantObjects('*.ElmLod') for load in loads_data: try: load_curve = df[load.GetAttribute('loc_name'] except: print(f'load curve for {load.GetAttribute('loc_name']} not found') #catching error because load name is not in data

Hi. I want to know if someone can help me in a issue that I´m having on Digsilent 2023... I want to know if it is posible to modify a setpoint value of a controller of a STATCOM during a RMS simulation; specifically when one specific line trips off (Meaning that the system would be running in N-1 condittions), for instance, at that moment when N-1 scenario occurs, instead of a setpoint value of 1 pu voltage at certain busbar, the statcom change that setpoint to look up for 0.98 pu. voltage.... Please if you can help me I´ll appreciate it.

Hi Everyone, did anybody know how can i create static generator objects in my project and then need to read date from csv file in order to give every photovoltic (static generator) their power and other properties??

Hello, . I'm trying to implement rms simulation via python code and I ran into a problem. I want to extract the value of a variable at a specific moment in time, but I don't know how to do it. can someone help me please? Regards!
