Synchronized Power Plant to Grid Station

Sure, why not?

Crank that sucker up to 55 Hz and show that mutha who's boss.

That'll bring it to its knees in short order.

You know that, and I know that, but if he doesn't know that, he shouldn't even be in a position to try.

Anyone foolish enough to come to an anonymous public forum for advice on how to run a bloody power plant deserves whatever answers he gets.

It would be nice if we knew what the question asker's native language was, then we could back feed that through Google's Universal translator and see what he was really asking. Then the engineers here could help him.

Just..no..don't do this. Consult a qualified professional immediately for assistance before doing anything. Seriously.

I shouldn't have to say this but on the off chance this is not a joke or a troll, running a power plant is a very serious affair and must be handled by trained professionals.

Comment about your numbers....

1 Correct.

2 When 11kV bus available, 11 kV/400V and 11kV/?? volt transformers must be connected to provide auxiliary power for prime mover, generator and site. Only then can genset be started and synchronized.

3 The phase sequence cannot be matched except by correct connection of busbars or cables to switchgear. Once built, prime movers only turn in one direction but generators theoretically can turn either way to change sequence. Once voltage and frequency are matched [usually 2% voltage & 0.1 Hz difference are acceptable] 11 kV breaker must be closed at right [in phase] moment in "slip cycle" using phase indicators and manual close or [usually] automatic synchronizer unit ASU.

4 Once connected, individual generators on a Grid usually have negligible effect on frequency. About 750 MW is required to change frequency of 25000 MW 50 Hz Grid by 1 Hz. Increasing the prime mover power driving generator will increase power delivered to Grid without change of frequency.

thanks for the brief reply,

if we increase the primover to meet the load put on the genrators from the system which we connect then the frequency change and may be increased then the system frequency ?

It sounds like you, anonymous grasshopper #1, may need to study on the topic a bit more before we can place the controls into your hands.

Please revert back to square one at HR, and they will provide you with a map to your next learning station.

Adding a "slave" unit onto the grid "master", does not change the frequency, although if things are misaligned as badly as you seem to intimate, there could be a sudden release of excess smoke contained within the wires and connections.

You are right to question my item 4!

Much power supply theory simplifies by assuming Grid frequency is fixed and synchronous generator theory shows that increasing prime mover power does increase electrical power delivered to Grid with fixed frequency.

Systems with a small number of generators always need a control system [originally an operator with hand controls] which keeps frequency at near 50 or 60 Hz and spreads load around generators for best operating cost.

I refer you to http://www.gridwatch.templar.co.uk.

This is a time display of UK Grid. You will find that Grid frequency varies over day within operating limits of 50 +/- 0.2 Hz with considerable load variation. Frequency change plays its part in coping with unpredictable load changes.

It does not have to be 50.1, but it needs to be advancing phase just slightly, so that once the indicator arm reaches TDC, and the phase lamps dim to zero, the synd lever is activated at just that moment and no other. At that point, since the voltage was previously lined up, and now the phases are aligned and in sync, and the systems are physically attached, you need to increase load on your prime mover, and ensure that your generator does not end up in motorized mode. You will need to adjust VARS to maintain the specified power factor on your output load.
