When an electric appliance 28 is connected, the output Pe of an engine 22 is maintained by reducing the output of a generator 28 by the equivalent of the power A - B consumed by the electric appliance 28 while maintaining the revolution speed Ne of the engine 22. The revolution speed Ne of the engine 22 is then gradually increased by adjusting the field current If of the generator 18 while monitoring the output PG of the generator 18. When the output Pe of the engine 22 is increased by this control, the engine 22 is operated at a constant revolution speed and a constant output at the operation point P. Thus, the engine 22 is prevented from stopping due to a rapid increase in the load. Owing to a gentle change in the output, the emission is favorable. Since the output of the engine does not deviate from the output line of the engine with WOT, the fuel consumption is also good.
