- Parameter estimation method for induction machines using instantaneous voltage and current measurements Johnny Wladimir Rengifo-Santana Joseph Benzaquen-Suñe José Manuel Aller-Castro Alexander Alfredo Bueno-Montilla José Alex Restrepo-Zambrano Ingeniería Induction machines parameter estimation nonlinear estimation rotating machine transient This paper proposes an off-line method to determine the electrical parameters of an induction machine based on two instantaneous indicators (impedance and power). The method uses the induction machine start-up voltage and current measurements. Also, the proposed method employs a space vector dynamic model of the induction machine referred to the fixed stator reference frame. This model allows the representation of the instantaneous indicators in terms of the machine electrical parameters. An error function is defined using the indicators obtained from the measurements, versus the corresponding derived from the dynamic model of the machine. The estimated parameters are obtained by minimizing this error function by means of a constrained nonlinear optimization algorithm. The effectiveness of the proposed method was experimentally validated. The results from the model using the estimated parameters fit the experimental data sets with average error below 5%. 2015 artículo científico 0120-6230 https://www.redalyc.org/articulo.oa?id=43038630007 en http://www.redalyc.org/revista.oa?id=430 Revista Facultad de Ingeniería Universidad de Antioquia application/pdf Universidad de Antioquia Revista Facultad de Ingeniería Universidad de Antioquia (Colombia) Num.75
