General Discussion

Can anyone tell me how to fetch devices inside a sub-circuit based on java scripting?

Currently I am only able to fetch from currentCircuit() like below,

var cct = currentCircuit();
dev1 = cct.devices('Name','PhaseB_Arrester');
dev2 = cct.devices('Name','PhaseA_Arrester');
dev3 = cct.devices('Name','PhaseC_Arrester');

what if I had to fetch 'PhaseB_Arrester', 'PhaseA_Arrester' , and 'PhaseC_Arrester' from a sub-circuit named lets say ' substation'?

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

Hi,

I am trying to connect to a remote system which has the physical license dongle for EMTP Work V4.1.0.

But it shows an error stating that the hardware key ID is not installed correctly.

Does EMTP prevent working through remote desktop connection ?

Thanks!

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.

Good afternoon,

I would like to know how it is possible to initialize the line voltage before simulating the lightning stroke by LIOV toolbox.

Thank you in advance.

Best regards.

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

How can i sample an analog signal coming from CT's with 16 samples/cycle for a power system frequency of 60 Hz. Is there any block for this purpose?

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.

Is there any way to apply an internal short-circuit at stator windings (at a certain percentage of the windings) in a synchronous machine?  

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?
