Abstract: Systems and methods for controlling and methods for controlling the power factor in a generator system are provided. In some embodiments, the generator system includes one or more generators configured to supply power to a power grid, an automatic voltage regulator configured to regulate a voltage of an output of the generator to a set voltage and regulate a power factor of the output to a set power factor, and a controller. The controller is configured to detect a fault on the output and to adjust the set power factor of the automatic voltage regulator based on the fault. The controller is further configured to ramp the set power factor from the adjusted value to an initial value over a set period of time.
