This paper proposes parameterized models to predict core losses in the stator and rotor of a caged induction machine. The parameters are identified from results of finite element simulations, using a differential evolution search algorithm. To account for flux distribution and frequency characteristics, it is found that variable flux power coefficients for hysteresis terms are required for both stator...
This paper deals with the resistive losses in the deep-bar induction motor fed by a PWM inverter. The effect of harmonics from the inverter on the resistive losses of the induction motor is investigated by varying the amplitude or phase of the harmonics. The investigation is performed on 45 kW and 1250 kW induction motors. The equivalent circuit of the deep-bar induction motor is presented and used...
This paper is aiming at presenting parameter estimation using the Differential Evolution algorithm. Previously, evolution based algorithms has been applied to frequency domain data. Within this study, the Differential Evolution algorithm has been applied to time-domain data. Convergence of this estimation procedure, presented within this paper, is validated by using synthetic data. Results obtained...
This study aims to estimate equivalent circuit parameters for a synchronous machine. The need for equivalent circuits rises from practical applications. Accurate models are needed for control design and power system analysis. The research was conducted using the 2D finite element analysis and the differential evolution algorithm. As an input to the synchronous machine, a pulse is used within the FEA...
