Modelado en el dominio de la frecuencia de un variador trifásico de velocidad conectado a un motor a partir de un método de ajuste basado en medidas de corriente y tensión

Abstract

This paper assess the performance of a model fitting method in the frequency domain from v ñoltage and current measurements. This method is presented as an option for modeling in the frequency domain and the subsequent estimation of the current distortion caused by a group of non-linear loads,compared to complex models in the time domain. In this way, it may be possible to implement distortion evaluation scenarios in MCCs (Motor ControlCenters) with a lower computational cost than a time domain simulation.
