Hi,
I have a customer with 2 old Rolls Royce 250KVA 1978 model gensets which he want to use in sink maybe once or twice a year when the need arises. Both are still equipped with their original panels with breakers and then also a combiner panel when they are in sink. Controls are done manually and then hope for the best.
I suggest that we put VT's on say the red phase of each generator and connect that to an oscilloscope. Start genset1 and bring up to 50Hz and running stable. Start genset2 and sink the corresponding phases (red). Then close breakers on gensets and then close onto load.
As a second phase to take the VT output feed them onto a comparator and then vary the throttle control via a step motor to keep them in sink.
Do you think it can be done and how?
Awaiting your response. Thanking you in advance.
Friendly greetings.
Chris
