We operate a 10 Mw facility and we have been experiencing several trips due to fluctuations on the MVAR? We have checked all issues related to the AVR and we have found all OK? Can anyone help us? The grid voltage, internal voltage, all regular parameters look ok. MVAR fluctuate and there it goes the unit? What could be happening? Thanks!
