Generator GSU paralleling
Generator GSU paralleling
(OP)
Dear all,
is there any considerable problems of paralleling generators' GSUs with OLTC to the same busbar.
will there be any problem if operating the OLTC action is delayed from the first generator on the busbar to the last one?
This question is concerning thermal power plants with several generators (> 200 MW).
Thank you.

RE: Generator GSU paralleling
With OLTC or without, is not problem.
Do you have some synchrocheck ( 25 )?

Slavag the question is concerning the mismatch of the OLTC during operation.
Scotty mismatch and circulating current were the things I am looking for. Any literature about that, specifically for generator GSU?
Thanks.

So, as Scotty said.
But, from other hand: for what you need OLTC in GSU? Do you regulate reactive power with OLTC?

But usually the voltage steps are small enough that the operator's can make the required generator voltage adjustements to maintain the desired system and generator voltages.
