synchronization question

Your question is a bit confusing, you can synchronise a unit to the system because you have control over the unit speed and voltage, that is normal, to do so you have to select the synchronizer, that synchronizer is normally on the control panel for that unit only. System control then has control over the other circuit breakers on the infinite bus, as you call it, or the system at large. As a unit operator you will be advised by system, if necessary, to any adjustments to speed and voltage, if they need to close up the system.

Sir,

You cant synchronise 2 buses when you dont have control. Generally during synchronisation the first one is taken as REFERENCE where the voltage, frequency are maintained constant. Of course the reference one has a specific phase sequence. Now you have to bring the second one to this stage for synchronising. When you both the buses are independant & you have no control over them then you cant make them parallel as they have different voltage, frequency levels.

Synchronising means two make parallel two sources. Check synchronisation means a relay which supervises these paramenters & closes the breaker for paralleling the supplies

Thanks very much for the response. It helps.
