General Discussion

Hi,

I'm a new user of EMTP. Just would like to ask if EMTP can be used to perform dynamic simulation study similar to what PSSE can perform using its DYRE file?

Thanks.

Is it possible to model a substation ground grid in EMTP that includes the effect of lightning surge dissipation into earth?  I would like to calculate the voltage surge on control cable shields during a lightning strike to a grounded substation structure.

Any examples available?

How can we calculate the positive , negative and zero sequence currents of double circuit transmission line in EMTP?

Help

[1] How can I generate *.pun files by changing the line length and the ground return resistivity  from Javascript in EMTP?

[2] How can I assign a *.pun file to  a  FDline from Javascript in EMTP?

Would any one be kind enough to share the model of a small synchronous generator, including exciter and governor?

I am trying to model a 1.4MW diesel generator. I will greatly appreciate any help. I am struggling to stabilize it using the library components.

Regards.

Dear Ladies and Gentlemen,

this is my first forum contribution so please excuse me, if I should post anything wrong.

I have the following set up for my recent project:

3 cables with 2 conductors each (layed straight)

and another cable with 2 conductors which is continously transposed (twisted (like a twisted two-pair)).

Question:

Hi,

I am working with the HVDC MMC models. 

In the MMC controllers to calculate the parameter values (such as #Pctrl_Ki#) there is a script in the folder toolboxes, but if I change a parameter on that script the simulation result is same. That is why I want to know what values are the controllers using during the time domain simulation. Can anyone help me be by giving the information, how can I calculate or get these parameter values?

Thank you.

Sincerely,

Hi everyone!

Is it possible to load the new data in a computing machine EMTP during the calculation?

Thanks in advance.

While installing the EMTP 2.6 i am getting the Xgridctrl.ocx is not getting the register.

asynchrons motor with given data parameters is done perfectly.. even though speed calculation error. 

if the steady state checkbox is removed from the emtp stimulation tab...then it runs with variable speed...
