General Discussion

I am wanting to model a 50 MVAr 132 kV shunt reactor (1.11 H), which is being supplied as part of a 132 kV cable project.

As I am looking at ferroresonance issues, I'd like to model the reactor as a non-linear reactor.

How do I translate the reactor design parameters to a current versus flux relationship ?

The reactor must be linear to 130% pu of rated voltage (= 171.6 kV ph-ph). Maximum flux density in iron at power frequency, principal tapping and 130% rated voltage is 2.1 T. This is the only information available as it is still under construction.

Hi there,

I'm fairly new to the software and have been doing some analysis on EMPT using a frequency dependent model. I was wondering if someone could explain or refer me to a paper/journal/book, as to why I see negative voltage plots using this method and only positive voltages when using a constant parameter model. Does it have to do with the initial conditions on each phase (ie 1.1pu of say 118, -59, -59) and a negative polarity surge (ie connecting -ve end of current source to the system)

Cheers

I am inquiring following questions:

[1] Can I set simulation options and run the simulation (including setting simulation configuaration) from Javascript in EMTP?

[2] Can I link Javascript to Netlist file?

How can i model a vertical configuration indoor substation for ferroresonance analysis in EMTP?

Can somebody please instruct me on how to design a three phase inverter in Atp/Emtp. Manythanks in advance.

hello, may i ask for help on how to import the data from Matlab to EMTP?

thank you for answering my question.

hi,

how can I simulate a conductor with its screen? and the mutual inductance?

thanks

It would be interesting for all of us who have chosen EMTP to discuss the pros and cons of EMTP compare to other similar packages. So I hereby open the discussion about this.

Dear all,

I'd like to active one of my controllers at the time t_init and would like to use this time point (t_init) in my simulation functions. How could I get the t_init?

Thank you very much!
