Hello all,
Can any one give a explanation on the difference between VAr control or Voltage control on a synchronous generator automatic voltage regulator (AVR)?
I know by lowering the field current on one generator (two generators in parallel) you increase the VAr consumption going in to that generator which will read a lag Power Factor PF.
Also by raising the field current to one generator (two generators in parallel) you increase the VAr production going out of that generator witch will read a lead PF.
So if an AVR was in VAr control mode will the system voltage drop?
When is VAr control used?
When is voltage used?
How does it work?
Thanks
