Prime Mover input versus Generator output
Prime Mover input versus Generator output
(OP)
I was hoping someone could set me straight and maybe point me to some helpful technical papers or documents relating to prime mover input as a function of generator output. What I am really looking to find out is does a unit's prime mover input increase (connected to synchronous generator) as a function of real power (kw) or apparent power (kVA)? I am familiar with varying field current to adjust power factor and I'm curious if load on the prime mover also increases when generating further VARS (keeping KW constant).

RE: Prime Mover input versus Generator output
Output power of the prime mover (net power) plus the losses of the prime mover equals the gross power of the prime mover.
The losses of the generator are mostly related to the current.
With a poor power factor, the current for the same kilowatt output will be higher, hence the slightly higher losses with poor power factor, as mentioned by skogsgurra.
