Excitation, Governor and Power Stabilizing System Diagram?
Excitation, Governor and Power Stabilizing System Diagram?
(OP)
Hello all and thanks for your review.
We have applied for a utility interconnect which will use a 3.5MVA 3 phase synchronous generator, driven by a steam turbine.
A oneline diagram depicting the disconnects and protections was supplied and approved.
A follow up request for our application is:
Please provide an IEEE model block diagram of the excitation system, governor system and power system stabilizer (PSS).
Any guidance for where I can seek information to help create this block diagram?
Thank you, Triage

Can you cite an equipment mfg and/or product designation that I could look into for this?
It is interesting that you suggest the system is probably too small for a PSS, they followed the request saying that PSS may not be necessary and should be included as an optional component.
Governor and Excitation control equipment mfg?

But you should really be getting it from your actual suppliers. But for a 3.5 MW unit, you may not have much luck.

Appreciate all the help!

As far as I'm aware, there is no IEEE standard for governor control systems, so dpc's suggestion of getting a standard steam turbine governor model from say Woodward, Siemens, etc would be reasonable. I would also recommend getting a model for the steam turbine, which will give you the relationship between the steam valve position (i.e. output of the governor) and the mechanical torque / power output of the turbine (i.e. input to the generator).
Unless you're connecting quite a few of these units onto the network, I seriously doubt you'll need a PSS.
