Abstract
A method of controlling operation of a variable speed, constant frequency generator system is disclosed. During operation, loads may be added to or removed from the output of the generator system. A controller monitors the power output by the generator system and detects a change in the output power exceeding a predefined threshold. The change indicates the addition of a large electrical load. The controller quickly detects the change in power output and activates a relay to disconnect the load from the generator system. The controller then accelerates the engine of the generator system to maximum speed and reconnects the load to the output of the generator system.
