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!

I agree with chaitanya this may happen due to the variation
of reactance produced
by the capacitors connected to that line it will be better
to maintain the Power Factor 0.90 only every where and the
next and only cause is that AVR problem may be some loose
connection in power as well as control side because AVR has
to take care of that MVAR.
