Aplicação do algoritmo de evolução diferencial na estimação dos parâmetros elétricos de um MIT operando em regime permanente

Abstract

This work consists of the study about the electrical parameters estimation of a threephase induction motor, at permanent scheme, through a differential evolution algorithm, given that this motor has great importance in the national energy scenario, by being widely used in many industrial sectors. Therefore, it is extremely important the suitable control and drive of this motor, but for that, its parameters must be considered. Thus, the algorithm will have the purpose of estimating them through the minimization of an objective function that compares the estimated phase stator current with the acquired real phase stator current. For this purpose, the entire modeling of the motor and of the optimization algorithm, in addition to the computational simulations, were performed in MATLAB® software. Lastly, experimental tests were carried out to validate the proposed methodology, comparing the estimated parameters through the differential evolution with the parameters determined by the no-load and locked rotor tests according to IEEE Std 112-2017.
