Hi everybody,

I am writting in this opportunitty because I would like to ask if someone have worked/programed FACTS devices UDM Fortran models.

In this opportunnity, for a FACTS device (UDM Fortran code) I would like to program some protections; and if a fault appears in the system I would like the FACTS UDM device to trip.

For machines I usually use GENTRP(IBUS,I) command in Fortran and I call this function for trip de machine, but what should be the similar function for a FACTS device? I was looking in the documentation but I couldn’t find any.

Thank you in advanced.

Good morning,

I have a question regarding the different PSS/E versions.

I’m creating a User Defined Model and this is compiled for the PSS/E version 34.4.

It is possible to use this UDM compiled for v34.4 in the PSS/E versions 34.5 and 34.7?

Thank you in advanved.

Hi everybody,

I am writting a very long user defined model code for PSS/E, so I would like to know if is possible to separate the code in different fortran files and then compiled them together with the PSS/E compiler? It is really annoying fix a bug with such amount of lines in the same file.

Thanks in advance.

Hi everybody,

I had created an user defined model code in Fortran for PSS/E and then compiled into a .dll for develop dynamic simulations. I am going to start to use PSCAD so I would like to know if is possible to use the Fortran developed for PSS/E in PSCAD because I need to build the same user defined model. Have somebody done something similar? Does PSCAD have some API document as PSSE for build its own user defined models using Fortran?

Thanks in advance.

Hi everyone,

Does anybody know if the IEEE SCL2C stator current limiter model is available in PSS/E?

I was looking in the Model Library document of PSS/E 34.6.1 and I couldn't find it in this version.

I would like to know if this models is available in a more recent PSS/E version.

Thank you in advanced.

Hi everyone,

Does anybody know if it is possible to used an IEEE library from PSS/E v34.5 in PSS/E v32.0?

For example, I would like to use the IEEE SCL2C (Stator current limiter model) and the IEEE ST10C (excitation system model) models, but these models are defined in PSS/E v34.5 but not in v32.0, is there a way to copy them in this version?

Thank you in advanced.

Hello everyone,

Is there any problem if an user model (.dll) is compiled in PSS/E v34.4 and later used in PSS/E v34.3 ???

A third party sent me a model compiled in PSS/E 34.4 using Intel Visual Fortran 2017 & Visual Studio 2015 in 64 Bit Operation System, but when I try to do the simulations in PSS/E 34.3 an error appears: "Library not found (000281)".

Is this error appearing because the PSS/E versions are different or because the IVF Fortran & VS software versions used for compiled the model are not the correct ones? As far as I know PSS/E 34 (in general) requires IVF 2015 and VS 2013.

Thank you

Hi @txc I found how to write both renewable generators using just one WAUX :D Thank you for your replies!

2/2 @txc signals two this second generator but I do not see any control. I have tried with other generator udm whose have the inputs defined as VARs and if I placed a second generator works as fine, but the issue is when the inputs are defined as arrays.

1/2 - Hi @txc I already made the interface between the auxiliary signal model with the generator udm inputs (WIPCMD(I) and WIQCMD(I)). The issue is I connected another generator udm (this one does not have any auxiliary control) and I updated the auxiliary control to send the WIPCMD(I) and WIQCMD(I)

Hi everyone!

I will try to explain my doubt with an example.

I have build my own WAUX (Wind auxiliary control) UDM model and placed it in bus bar No 100; for example; and also I placed the UDM renewable generator associated. For control of the generator I am writting WIPCMD(I) and WIQCMD(I) arrays with the WAUX results. This is working perfectly.

Now, I have to connect other UDM renewable generator this time in bus bar No 200, and I need to control this generator, as the one placed in bus bar 100, by writting its WIPCMD(I) and WIQCMD(I) arrays with the values of the WAUX placed in bus bar No 100.

Do you know if is possible to write WIPCMD(I) and WIQCMD(I) of renewable generator in bus bar 200 with the results of the WAUX placed in bus bar 100.?

Thank you in advanced.

HI @txc at the end I found how to write WPCMND(I) and WQCMND(I) :) now the wind generator udm and my auxilary control udm are working together as expected! Thank you very much for your previous answers!

Hi @txc the wind generator is reading WPCMND(I) and WQCMND(I). I already started to program my Auxilary Control Model code but right now I am not so sure on how to pass the information to those parameters. Any suggest?

Hi @txc thank you for your response :) In this case the renewable machine is also an user defined model made by a third party, so I would like to create the UDM for the Auxiliary Control. It is the wind model arrays being affected if the machine is an UDM model as well?

Hi everybody,

I am writting in this opportunitty because I would like to ask if someone have worked with the Wind Auxilary Control Model of a renewable machine?. I would like to build an auxiliary control user defined model for the renewable machine I am using but I would like to know if building the model from scrach should follow some specific requirements.

I have some experience creating UDM models for syncronous generators but this is my first time working with the slots of a wind generator.

Thank you in advanced.
