Can power factor be different in each side of a generator transformer that's connected to an infinite bus (grid)?
Example...
Generator at LV connected to a HV public utility grid via a step-up transformer. The generator is running in 'power factor' control mode. This means that the alternator will always run at the desired power factor, in this case it's unity. There's more than enough reactive power being generated elsewhere on the grid for load that requires it.

In a word, yes.
The transformer is a load on the generator/system. One of them (or both) have to supply the reactive requirements which will be reflected in the power factor.
All that being 'infinite' confers to a bus is constant voltage for 'any' load. It says nothing about the power factor of the load.
Hi
Generator is running in constant power factor mode so all generator that are connected to same grid through the unit transformer shall see the same power factor anywhere in the grid connected system

see strictly speaking there will a very negligile difference in power factor betwwen LV AND HV sides of transformer. it is because a transformer draws a negligible magnetsing current ( reactive power) to maintain the varying flux and a very little real power due to the loses in it. so if u ask me i will just say NO. because what that a transformer draws a just a trivial thing right. bye
Under any significant load, the pf on both sides is, for all intents and purposes, the same. Under very light load, the small magnitizing current within the transformer will make the supplying side have a different pf then the load side.
