Harmonics Analysis of Six-Phase Induction Motor Drive Mohd. Rizwan Khan, Md Nasim Akhter, Mohd. Sartaj 2023 International Conference on Power Instrumentation Energy and Control Piecon 2023, 2023 In high-power applications, including ship propulsion, aviation, military, medical device applications, and paper mills, multi-phase induction motors are used because of their enhanced torque density, fault tolerance, volume reduction, noise reduction, and current per phase. This research examines three stator supply methods for six-phase and three-phase induction motors. A six-phase inverter and multi-phase transformer conversion approach compare the harmonic behavior of six-phase and three-phase induction motors.
Consideration of Dynamic Cross Saturation in Mathematical Modeling of an Asymmetrical Six-Phase SEIG for Wind Energy Applications Mohd Rizwan Khan, Mohd Faisal Khan, Mohd Sartaj Pesgre 2022 IEEE International Conference on Power Electronics Smart Grid and Renewable Energy, 2022 Compared to three-phase, the multi-phase electrical machine technology renders a reduction in size and weight and an increase in efficiency and reliability of the machine. Self-excited induction generators (SEIGs) are preferred for wind energy conversion systems because they are simple, low-cost, and durable. It is vital to get comprehensive insights into an induction generator’s dynamic behaviour to develop an effective control system governing its voltage, frequency, and reactive power. This study analyses the performance of two non-linear models of an asymmetrical six-phase SEIG using stator and rotor currents as state variables. The mathematical models of SEIG differ in terms of the presence or absence of a dynamic cross saturation effect. Transient events, including voltage build-up, sudden load perturbation, and unloading of the six-phase SEIG, reveal substantial performance variations between the studied modeling approaches. When comparing the full model (which contains the cross-saturation effect) to the simplified model, the full model shows a faster steady-state convergence. Experimental and simulated results are presented to support arguments.
Analysis of Considering Dynamic Cross Saturation in Mathematical Model of a Symmetrical Six-Phase Self-Excited Induction Generator Mohd Rizwan Khan, Mohd Faisal Khan, Mohd Sartaj Proceedings of 2021 IEEE 2nd International Conference on Smart Technologies for Power Energy and Control Stpec 2021, 2021 The onset of the multi-phase technology for electric machines reduces their size and weight and improves efficiency and reliability compared to three-phase counterparts. Because of its simple, low-cost, and durable construction, self-excited induction generators (SEIGs) are favorable for wind energy conversion systems. Gaining deep insights into an induction generator’s dynamic behavior is crucial for designing effective control systems to govern its voltage, frequency, and reactive power. Present work undertakes performance comparison of two non-linear models of a symmetrical six-phase SEIG using stator and rotor currents as state variables. The considered models differ in the presence and absence of dynamic cross-saturation effects in their mathematical models. The performance deviations are observed quite clearly in transient events such as voltage build-up, sudden loading, and unloading of the six-phase SEIG. The presented work shows that the full model (considering the cross-saturation effect) has faster convergence to steady-state than the one neglecting it. Presented work shows experimental and simulated results to validate arguments.
Modelling of Five-Phase Induction Generator Incorporating Magnetic Cross Saturation Effect Mohd Sartaj, Mohd Rizwan Khan, Mohd Faisal Khan Proceedings 2019 International Conference on Electrical Electronics and Computer Engineering Upcon 2019, 2019 Due to the depletion of fossil fuel and problems of pollution associated with them, the contribution of renewable sources of energy is increasing day by day to encourage sustainable living. Various researches are going on in the field of solar and wind power generation to achieve this goal. With inbuilt attributes of robustness, exciter-less operation and squirrel cage structure the Induction Generators (IGs) are well suited for application in wind energy conversion system (WECS). Further consolidation of these attributes may be achieved by using high (more than three) phase machine for IG operation. In high-phase machines the per-phase current can be reduced without increasing the per phase voltage for the same power rating. In this study two non-linear dynamic models for a five-phase induction generator are compared. One of the models includes magnetic cross-saturation effect and is referred as the full model while the other one is simplified model that neglects magnetic cross saturation and other non-uniformities of the machine.
Comparative Performance Study of Five-Phase Induction Motor Zeeshan Sarwer, Mohd Sartaj, M. Rizwan Khan, Mohammad Zaid, Umair Shahajhani 2019 Innovations in Power and Advanced Computing Technologies I Pact 2019, 2019 Research in the area of multi-phase machines are attracting more and more researchers due to the inherent advantages of these machines. In particular, there is a rapid increase of research work being carried out on multi-phase induction machines. A Five-phase supply is an obvious requirement to make the operation of a five-phase induction motor possible. To fulfill this particular requirement, the possible choices may be to use a three to five-phase converting transformer and the other option is to use rectifier-inverter set i.e. a three-phase rectifier combined with a Five-phase inverter. This paper attempts to provide a comparative analysis of the performance of a five-phase induction motor when the motor is supplied through each of the two methods. Also, this work presents the effect of unbalanced input voltage fed to the five-phase induction motor. Simulation has been performed for different cases and obtained results of different parameters are shown here. MATLAB/SIMULINK platform is used here for performing the simulation.
