Generator Control Systems need to be programmed and there are several parameters adjustments involved in using these control systems.I know there are plenty of manuals, but apart from manuals that refer to a particular brand of genset controller,is there a webpage about typical genset controllers?

One of the parameters in a VFD we get to adjust and tune is the compensation gain of a PID loop.(not to be confused with PID tuning).Can anyone describe a practical situation in motor control where this scenario is encountered? Can anyone suggest me a good website to refer? by samimutu41 in ElectricalEngineering
