YES WARREN  THAT IS CORRECT AND THAT IS  ANOTHER APPROACH INSTEAD OF AC THEN DC  THEN BACK TO AC THE 3 PHASE VIA SUITABLE TRANSFORMERS WOULD BE EFFICIENT.
GETTING SUITABLE TRANSFORMERS COULD BE A PROBLEM BUT I HAVE SEEN NORMAL 50 Hz TRANSFORMERS USED BUT HANDLING LARGE CURRENT MIGHT BE A PROBLEM

Stefan, Mal,
 
   Very interesting project !
Automotive alternators are actually 3-phase ac alternators with a bridge rectifier to get d.c.
If you could remove the bridge you could feed the A.C. into a step-up transformer for transmission at higher voltage/lower current.

Mal,

100A?
What is the cable length Mal? 2x 100m, using 2,5mm^2? Or do you use an inverter next to the generator output to transform up to 200V or so?
