Abstract

La caracterización energética de motores de inducción se dificulta por el volumen de mediciones y cálculo a realizar cuando el número de motores es superior a la decena. En este trabajo se desarrolló un modelo de motor de inducción agregado que permite la caracterización energética equivalente al grupo de motores. El modelo de motor de inducción agregado se obtuvo por balance de potencia entre el equivalente y los motores individuales en régimen estacionario. Se utilizó la herramienta SimPowerSystem de MATLAB en la simulación del motor agregado y los motores individuales para determinar el comportamiento energético ante las cargas acopladas y comparar los resultados. Los cambios en las cargas de los motores individuales originaron respuestas en las magnitudes del motor agregado con errores menores del 5 % comparada con las respuestas resultantes del grupo de motores, concluyendo que el agregado respondió satisfactoriamente y existe una equivalencia con fines energéticos al grupo de motores.

Palabras claves: motor de inducción, motor de inducción agregado, caracterización energética.

Abstract

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.

Key words: induction motors, aggregate induction motors, energetic characterization.
