ROMERO-RUEDA, Ignacio; PEREZ-MENA, Bárbara M.  and  GOMEZ-SARDUY, Julio Rafael. Aggregate induction motor model applied in energetic characterization. Ingeniería Mecánica [online]. 2012, vol.15, n.3, pp.213-223. ISSN 1815-5944.

The energetic characterization of induction motors is difficult by the volume of measurement and calculation to carry out when the number of motors is bigger than the tens. In this work developed a model of aggregate induction motor that allows the equivalent energy characterization to a group of motors. The model of aggregate induction motor was obtained by the balance of powers between the equivalent one and the individual motors in steady-state. Used the toolbox SimPowerSystem of MATLAB the aggregate motor and the individual motors are simulated, to determine the energy behavior before the coupled loads and to compare the results. Changes in the individual motors loads originated answers in the magnitudes of the motor aggregate with errors smaller than 5% compared with the resulting answers of the group of motors, showing that the aggregate responds satisfactorily and exists an equivalence with energy conclusions to the group of motors.
