Hi

Is there a quick way to convert PSS/E .dyr file to PSLF .dyd? Is there a way to extract the file in .dyd format from PSS/E?

Thanks, Omid

Yes, it is modeled as wind machine, and I can see the modules load up in DYR when I load the dyr file in PSSE. What is Erun? How do I enable Erun? I don't see it listed under Dynamic Disturbances menu? Is Erun the equivalent of Vref step change that works for renewable models?

I'm trying to implement a step voltage change in a generator modeled with WECC second generation models, i.e. the exciter is REECA1.

WHen I apply the 'Dynamic Disturbance' 'VRef, I get an error that 'there is no excitation system model.'

Does anyone know if the VRef (V step change distrubance) doesn't work with REECA1 or wind models? Is there an equivalent?

Thanks

Thank you, I think that works, though the response is not as good as Power World. But anyways I think that's how that works. BTW how about TSTGOV1? Is it better than PLBVFU1 for testing freq step?

Thanks for the prompt response; but I'm still puzzled...a swing bus by definition is one where P and Q cannot be assigned...so how could I set the P and Q there exactly equal to 0 (I can only fix V and angle at the swing bus)?

Many thanks; the manual, however, says: "PLBVFU1 model must be attached to this generator with the following conditions: Vscheduled =Vinitial of the bus, generator Pgen = 0.0, and generator QMAX=QMIN=0.0." How can the slack gen have Pgen=0 and Qmax/min=0?

Many thanks;what I mean is,this will only graph what was gathered in the field right?What I'm trying to do is this:I have modeled a generator,G1,with models GENTPJU1/ESST4B/WSIEG1,and a slack gen.I want to now make a system frequency step change and simulate G1's gov response. Would PLBVFU1 do this?

Thank you for the answer; it looks like that model is to 'play in' field-measured signals, rather than force a frequency step for the generator I'm trying to simulate, is that correct?

Hello,

I have a frequency step test, dynamics study.

In Power World, one is able to simulate a frequency step test by changing the frequency at the slack generator.

In PSS/E, I couldn't find an equivalent 'disturbance' to emulate a frequency step test. The closest I found is the GRef, but I understand that changes the Pmech of a generator directly, instead of emulating a frequency step change. Is this correct? Or does PSS/E have a frequency step function similar to Power World?
