A study of starting current due to a group of induction motors using an aggregation model

This paper presents a generalized aggregation model for representing a group of induction motors. The mathematical equations and computer models are detailed. The model, then, is used to predict the starting current from the group of induction motors. Tests are performed on various sizes of induction motors so that the model can be verified. Results, obtained from measurements, are compared with those from simulations. It is found that the proposed aggregation model is able to give satisfactory results for determining the starting current from the group of induction motors.
