1. A method of controlling an engine-driven, electrical generator system configured to generate an alternating current (AC) power at a desired output frequency for a plurality of electrical loads, comprising the steps of:

  • determining a value of the AC power output by the generator system at least once during each electrical cycle of the AC power;

    detecting a change in the value of the AC power output greater than a preset threshold;

    opening a switch to disconnect at least one of the electrical loads from the generator system responsive to detecting the change in the value of the AC power output greater than the preset threshold;

    accelerating the engine to a maximum operating speed; and

    closing the switch to reconnect the at least one electrical load to the generator system upon acceleration of the engine to the maximum operating speed.
