Torsional Dynamics of Generator-Units for Feeding Induction Motor Drives

The paper analyses the torsional dynamics of generator-units for feeding induction motor drives. A unique mathematical model of the integral motor drive has been developed, consisting of: a Diesel engine, a synchronous generator and a non-regulated motor drive fed directly from the generator-unit terminals. The validity of the mathematical model was checked by comparing the results of simulation and measurement on the generator-unit with a Diesel engine of 46.4 kW and a synchronous generator of 40 kVA, to which a motor drive of 7.5 kW was connected.
