Abstract: Pulsations in an electrical parameter on the output of a synchronous generator powered by a Diesel engine at a frequency which differs from that of the synchronous generator's natural frequency are smoothed out, whereby, a controlled variable (X) corresponding to the pulsation is tapped from the stage formed by the Diesel engine (5), the generator (3), and the network (4). From this controlled variable (X) and a reference input (W), a control difference (.DELTA.) is calculated, by means of which a correcting variable (y) is set in the stage indicated for the purpose of control.
