Torsinal Dynamics of Generator-Units during the Start-up of the Induction Motor

The paper analyses the torsional dynamics of generator-units during start-up of induction motor. A unique mathematical model of the integral motor drive has been developed, consisting of: a diesel engine, synchronous generator and non-regulated motor drive fed directly from the generatorunit terminals. The mechanical system of motor-generator set is modelled as rotating system with two concentrated masses connected with elastic coupling. The main objective of this paper is to take this elastic coupling into consideration and analyse torsional dynamics in the coupling. The validity of the mathematical model was checked by comparing the results of simulation and measurement on the generator-unit.
