Synchronous Condensing capability of a typical turbine generator

[123MB]

Hi all,

For a typical turbine generator in the MWs range , i.e. a Mercury 50, what work is theoretically required for it to provide synchronous condensing capability while it is not generating.

I am not talking about decoupling the generator from the turbine, I am more talking about the excitation and associated control, and even starting it up.

Is this something that is typically done without any modifications required?

I have been researching and it looks like it is common for hydro power plants to be retrofitted to provide this functionality and I have been trying to determine if the excitation and associated control are changed but I can't get much information.

Also, it looks like Hydro generators are a popular choice for this kind of conversion - why is this? Is it due to their typically high inertia?
Thanks all

You already asked this question here

What are your additional / different questions now?

Note that gas turbines, and particularly their compressors, will absorb a considerable amount of real power when motoring at synchronous speed.

Note also that steam turbines will have to be supplied with "ventilating" steam to prevent blade overheating if motoring.

Oh my god, I am so sorry, I totally forgot that I wrote that post!

My apologies Sir and all!
