Feedback voltage usually come from potential transformer connected at generator output

When feedback voltage is lost to the AVR, there is still an open-loop control (voltage reference setpoint) as well as an inner stabilizer that will kick into action if the field voltage drops. Thru amplifier action, the field current will be boosted to compensate for the drop in field voltage. There are AVRs that have feedback from field current and field voltage to prevent exactly this sort of collapse. So you will not have terminal voltage regulation, but may be able to still supply power. If on the other hand, the field voltage collapses entirely, then as the previous poster writes, there will be no electrical power output. Read on IEEE AVR Types to get an understanding of this.

If there is no excitation voltage then there is no power output.

The generator may lose synchronization with the rest of the power grid and either overload or underload.
