Power factor correction for generators
Posted 11 October 2002 - 09:48 AM
Can I upgrade power factor of genset for ex. from 0.8 to 0.98 by using a power factor correcting system?

Yes, you can increase the power factor by adding correction, however I would not go too far!!
If you have a single generator, the impedance will be moderately high and if you correct to too high a value, you stand the chance of resonances and rising voltages. I am not sure what is the mazimum pf that you should aim for, but would suggest that if you were at 0.95, you would have little to gain by going further and less problems with resonances.
Perhaps you should aske the genset supplier what they recommend as a maximum. - we would be interested in their comments also.

The engine is loaded by KW and the alternator is loaded by Amps.
To correctly size and match, you should select the engine on your KW loading and th alternator on your Amp or KVA demand.
