Infinite Generator
I'm setting up a case representing an infinite generator. I assume modeling this dynamically is just as simple as having a large inertia and large damping coefficient for said generator?
Thanks

The short circuit power in MVA for the "infinite bus" is determined by Mbase/Zsorce. Select GENCLS with H=0 to make the generator infinitely heavy in the dynamics (infinite inertia and constant frequency)
can you explain why the H should be zero please?? i thought with higher values of H , less movement of the frequency, thanks
In GENCLS model, H=0 menas infinit inertia. It is explained in the model sheet for GENCLS. The frequency will be constant during the whole simulation, i.e. PU speed deviation =0.
thanks a lot!!
I have done same .. On tripping one of generator ... Initially, my infinite generator is picking up the load, however, later , that additional load is being distributed on all of remaining generators and infinite generator is going back at its initial load... whereas, I want to have that infinite generator to keep serving that deficit..
I wanted to attach the Pelectrical images for your reference.. however, website is denying by saying to "not have Karma>10"...
What is the purpose of this Xsource = 0.01 ? What is the relation between the modeling Infinite Bus and the Xsorce parameter ?
jesus...is no one else running into this problem?!?!?
I decided to post in here because my question is relevant: "How do I model an infinite bus?" To be more exact, I need to model many infinite buses so "How do I model a number of infinite buses in a case?" I am asking in both load flow network data and dynamic model terms.

Thanks jconto, the damping and inertia coefficients should be large though correct?
Yes, that is correct.
The damping factor shall be zero!!!!!
