Method for operating a combustion engine coupled with a generator and device for carrying out the method

The invention is a method and a device for operating a system (10) comprising a generator (12) and an internal combustion engine (14) driving the generator (12), wherein a rotational speed of the generator (12) is regulated by means of a speed controller (34), which is characterized in that the speed controller (34) outputs a target torque as a control variable and that the target torque is subjected to an additional torque, wherein the additional torque is calculated or determined on the basis of a measured value acquired from the system (10).
