Wind turbine generators
Wind turbine generators
(OP)
How is shunt-capacitor size chosen for this wind induction generators farms?
I need rule of thumb if possible. I understand there is range for generator power factor, i.e 0.9 leading p.f. to say 0.95 lagging. Does this mean that VARs are exported to the grid in preference? If gen is 1500KW then capacitor need to be huge (1200KVAr)
Reason why I ask this is I need to model this generator, and I am stuck right now with what capacitor size to use , one for exporting or importing reactive power.

RE: Wind turbine generators
This is typically done a per-turbine basis with switched capacitors. Var requirements change with output (wind speed). If you size the cap bank to correct to 1.0 at full output, you're going to be overcorrected most of the time unless you have a lot of switched stages. Wind farms average only about 30% output on average.
Induction generators have horrendous power factor when generating. Much worse than motors.
