General Discussion

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,

Ahsan (KTH)

Hi everyone!

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

Thanks in advance.

Ignat.

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...

I am looking to model wind turbines for the purpose of an insulation co-ordination study.

Due to the damping effect of  the transient overvoltages when there is a generator power flow into the wind farm network, I am unsure on most most accurate way to represent them.

Any help would be greatly appreciated

Hallo everyone,

I want to create a simple model in EMTP that has many almost identical parts. For example 100 capacitors in series, but each one with a different capacitance. Is there a way to quickly create this circuit with a script?

It is very tedious to double click on all devices and change each and every parameter every time there is a new model.

Cheers,

Ronald

Hello everyone!

My experience of EMTP usage is connected to investigation of electric railway system influence on metal structures located nearby railway overhead lines. I found that EMTP is the appropriate software program for railway system modelling, current distribution analysis (interfering current) and induced voltage calculation.

Compared with other similar software program, EMTP is easier to use: the user friendly desktop calculation allows fast modelling, calculation time is shorter and possibilities of result analysis are excellent.

The associated EMTP help link for BCTRAN Transformer Data Calculation has poorly formated formulas. Does anyone have a clean readable pdf of this help topic.

I have been studying DFIG based wind turbines.

I just want to know....

what are the improvements of the DFIG model in version 2.5 compared with the DFIG in version 2.4?

Thank you.
