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.

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

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

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

Hi I makesure this issue not relevant with the ComAp Controller. I think we need to adjust the PID, OVR gain so that the generator respond to sudden load increases and sudden load reductions.

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...

Thank you @ControlsGuy25,PhilCorso. -Today we follow the process of suddenly increasing the load from no load to 50% of the load, then the motor can meet. From 50% to 100% ( 40kw to 80kw ) load, the engine speed gradually decreases from 1500rmp to 860 rpm and then shuts down. (If every 20kw...

Thank you very much for your comments. ( munna, ControlsGuy25 ) The generator is runned standalone, not yet synchronized. Currently I'm load test to check generator load response. Today I isolated the control wire from the main electrical panel to the governor and ran the test again, the...
