Grid Tied PV with Reduced THD Using NN and PWM Techniques

Abstract

Modulation of the PV inverters has been shown to significantly minimize the harmonic distortions found with Pulse. For three phase squirrel cage induction motors, Harmonic Tuning is important. Reducing the THD in the three phase squirrel cage induction motor allows for improvement in motor output. This study looked at the three-phase induction motor's harmonic distortion in terms of simulating it with the sinusoidal feedback, comparing it to the sinusoidal input values for optimal performance. To cut down on VTHD, using the PWM method was used on the three-phase induction motor. Neural networks are used to find the THD with the least amount of distortion for a given frequency. You have set the chosen modulation amount and frequency to the inverter's input. at this stage, we have the ability to link the PV circuit to the grid.
