Use Chart recorder too it help for PID tuning ....

I have. ^^! It's quite good so that to follow and review the engine speed.

 

The main problems is how to control the generator with sudden load test

I still do not know if the problem is related top Diesel engine (Prime mover ) than Generator itself...
What you mean by "control the generator " ...you should provide details on droop /isochronous mode scheme installed..

Regarding the datas that you provided ...and assuming that tehre is no alrms coming from AVR ..problem reside mostly on Prime mover controls system configuration /tuning...

Thank you @ControlsGuy25
I used PST to record RPM when I increase load and then load steady to check when there is abnormality.
I adjust the parameter by User interface because the generator reacts faster than adjusted with PST.
Attached photo below is a original of the generator. And it's not control the generator when the load increase from 0 to 50% load and decrease from 100% to no load.
I will increase the P ( Proportional ) and D ( Derivative ) and OVG to control the generator.
I will continue to check next Monday. If It will be OKE, I will begin the synchronizing 2 generator. The generator use AVR MX341 board.
Looking forward to your support ? Thanks

Derivative gain is decreased from 25 to 12...can you expalin why ...

It's from the manufacturer and that also is my question ^^! I think it is the best choice from them.

Hi james,
I still perform test the standalone generator, and i adjust the droop CT about 5% for noload follow the recommend from manual instruction ( AVR MX341 )
I think this problem we must be adjust the PID and Gain from Woodward Governo. It's cannot to control the generator.

 

hi lee tons same problem now I'm facing.
kindly assist me to solve the same problem. I'm adjust PID value but problem still present.

Hi

Can we get an update on this issue ..

Cheers
