[Vwdiesel] Genset talk for BEGINNERS ---- (using the VW diesels)

[Val Christian]

Hagar,

Aside from dynamic loads, can we not assume that the static load 
limitations (to avoid lugging, etc.) can be adequately provided
by limiting the generation capability of the altenator on the 
genset?  That will in turn limit the torque.

The industrial pumps, which I first saw using a 1.4 or 1.5l
VW diesel, had ways of limiting the torque on the pump, so the 
engine didn't lug (for example, with higher water lifts / head).

Power factor indeed limits the genset total output, but does not 
impact the powerplant operation, because if anything, lower torque 
is presented to the powerplant, due to the fact that PF will limit
to total power output.

To be fair, there are simply people who have to be off the grid, 
perhaps because of their location.  Grid prices are not outrageous, 
when you consider that a gallon of diesel is about 41 kWhr.  Assume
a 1/3 effiency, and you might generate 13 kWh of power, for a gallon
per hour.  The meter looks good.

All that said, I like the idea of grid independance, even if just 
long enough for the clean-up of the ice storm.
