1. In an isolated electrical power generation system having multiple isochronous, load-sharing engine-generator units including(1) load sensing means for generating a signal representing the individual power output of each engine-generator unit,(2) means for generating a signal representing the total power output of all the engine-generator units in said system, and(3) load-sharing means responsive to deviations between each individual power output signal and said total power output signal for controlling the fuel inputs to the respective engines in said units,the improvement comprising load simulating means responsive to the occurrence of a preselected condition in an individual unit for adding a simulated power output signal to the individual power output signal for the unit to reduce the fuel input to that unit without reducing said total power output signal, thereby avoiding a reduction in the fuel inputs to the other units and a resultant reduction in the frequency of the power output of the system.
