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!

Hello everyone, somebody knows what is a "surplice power" ? The hole phrase is: "This rating is appropriate for a generator set paralleled with an infinite bus e.g. a national electrical supply network or grid where the generator set is run at 100% load, 24 hours a day, 365 days a year and any surplice power is exported into the grid" Thanks in advance.
