Motor drive experimental setup parameters determination

The training and practice of future marine engineers in the field of marine electrical systems in realistic conditions presents several risks, especially if the training is regarding high voltage electrical systems. In order to minimize the aforementioned risks, the training should be conducted on a simulation model that can adequately simulate the behaviour of the analysed systems so that the quality of the training is not affected. In this paper, the steady-state behaviour of an induction motor fed by a two-level voltage source inverter (2L-VSI) is investigated. Lucas-Nulle devices allow the measurement and recording of a large number of values such as voltage, current, slip, power factor, active power, reactive power, power, voltage and current frequency spectrum, modulation signal. In this work, the objective is to build a simple space vector modulation signal generator using "black box" library components in Simulink and use the measurement to validate the parameters of the inverter and induction motor. The results of the Simulink model on the motor side show good agreement with the measurement result, indicating that the motor parameters are correctly determined.
