Abstract
A method and apparatus are disclosed for controlling a genset having an engine and an alternator in order to prevent an excessive change in a speed of the engine because of a sudden change in a load on the alternator. The method includes obtaining a first measured value of an actual AC output power of the alternator at a genset controller during a first time period, and obtaining a second measured value of the actual AC output power of the alternator at the genset controller during a second time period. The method further includes determining at the genset controller a first output power based upon at least the first measured value, and a second output power based upon at least the second measured value. The method additionally includes determining at the genset controller, based upon the first output power and the second output power, whether the actual AC output power has changed in an amount greater than a first threshold, and providing a first control signal from the genset controller to the genset causing a position of a throttle to be modified when it is determined that the actual AC output power has changed in an amount greater than the first threshold.
