Problem to reproduce simulinkDLL examples

Problem to reproduce simulinkDLL examples
Hi,
When I try to build Simulink DLL, I get the following error.
CRL: "None" cannot be found in the registry.
It is because that the interface is set to "None," and when I choose C++ ISO, it works and generates two folders but gives the following warning.
EMTPInterface.cpp
EMTPInterface.cpp(37) : warning C4018: '<' : signed/unsigned mismatch
EMTPInterface.cpp(39) : warning C4267: 'initializing' : conversion from 'size_t' to 'int', possible loss of data

Import excel file to "Table function voltage source"

Submitted by Ganga on Sat, 07/31/2021 - 19:47

I was trying to import an Excel file into "Table function voltage source". 

First, save excel file in CSV format. Then, open with notepad and save as xxxx.dat file. 

I import that file into "Table function voltage source" and ended up with the following error.

Could you please help me to import an Excel file into EMTP?

 

Thank you.

Building short circuit equivalent in EMTP - Phase shifter

Submitted by rpandia on Tue, 06/15/2021 - 01:19

Hi, 

I am trying to build a short circuit equivalent in EMTP.

I had created the short circuit equivalent of a large network in ASPEN(using in-built function) and I have a phase-shifter in my ASPEN equivalent which also has a negative sequence component - R2&X2 values.

How can I implement this component in EMTP? I can see a phase-shifter in EMTP but with only positive & zero sequence inputs.

Thanks

Dear Sirs, I believe that I have seen some of video presentations from Virtual User Conference several days ago on Youtube page. 

Currently I cant find them so I guess that these videos were removed from Youtube page.

Is there possibility to post them again for some period of time or is there any other way to apply in order to get video presentations.

 

Wind turbine model

Submitted by francisarody on Wed, 01/06/2021 - 21:49

Hi, i'm trying to model the dynamic response of a wind turbine-generator system but i don't know how to couple the mechanical torque to the electromagnetic torque of pmsg generator, already modeled in the EMTP-RV. The mechanical torque was obtained from turbine model and basic mechanical power equations by using the control blocks of EMTP-RV. Also, i don't know the correct way of initilization of variables. I'm not using the per unit values. I'm connecting a three-phase resisitive load at generator terminals. Can you help me?

Run .DWJ with command line similar to .NET files

Submitted by beikbabaei on Sat, 11/28/2020 - 16:06

Hi,
I start working with EMTP for a few days Thanks to h.gras guidance I can execute file_name.net by this command "emtpopt.exe "path\emtpstate.ini;;file_name.net;1;"" Can anyone help me to run a DWJ file from a command prompt. I can run the DWJ file by clicking a push bottom.
Regards
