In the modelling of induction motor drives it is common to choose only a first order representation of the torsional elements of the motor drive. When there is a requirement for more detailed information on the behaviour of the torsional elements of the drive a method of analysis is often chosen which inherently suppresses the important features of interaction between the torsional elements and the drive motor. This can lead to completely erroneous results as to the level of transient torques seen at various points in the drive during faults or switching operations. The analysis is often further simplified by the neglect of mechanical system non-linearities, the most important of which are backlash and torsional couplings having non-linear stiffness versus deflection characteristics. The paper discusses the basic modelling problem and highlights the differences in computed responses obtained when using mechanical system models of varying complexity. The practical implications of this topic are highlighted by examining the behavior of a power station circulating water pump and the practical problem areas are stressed. Comparisons of dynamic torque-slip curves for the drive motor with a single inertia representation of the mechanical load and those obtained with more complex modelling are shown |
