PV System Based Speed Control of Induction Motor by Space Vector Pulse Width Modulation

This work uses green energy to solve the problem of lacking electrical energy in agricultural areas. Thus, it suggests using photovoltaic systems to supply the engines used in irrigation in these areas where the load is variable. In addition, this work uses a three-phase inverter to achieve the lowest possible total harmonic distortion. Furthermore, the motor's torque is fixed at all speeds, while the volt-to-hertz ratio speed control of the induction motor is discussed in this paper. By varying the modulation index of the space-vector-pulse-width, the stator voltage of the induction motor can differ correspondingly. The time duration of gate pulses is changed to maintain the constant voltage-to-hertz ratio. Space-vector-pulse-width-modulation technique delivers the simulation and theoretical analysis. Moreover, PV cells drive the induction motors with a wide speed range. Simulation results were validated with practical outcomes.
