The influence of impact load on torsional dynamics of generator-units for feeding induction motor drives

摘要

The paper analyses the dynamic behavior of generator-units, as well as induction motors, during start-up of the induction motor drives fed directly from generator-unit terminals. A unique mathematical model of integral motor drives has been developed, consisting of: a diesel engine, a synchronous generator and two non-regulated motor drives. The aim of this paper is to compare dynamics behaviors of the generator-units during starting the second induction motor that coresponds with conection of load on first induction motor shaft.
