Sensorless SRM driven Solar Irrigation Pump with Grid-Support Using Vienna Rectifier

This paper presents power quality improvement in AC mains of grid-supported solar fed switched reluctance motor (SRM) water pump drive using a three-phase Vienna converter. The Vienna converter used at the front-end improves the quality of power drawn from the utility grid by reducing the harmonics and maintaining the unity power factor. Besides these features, The Vienna converter provides the DC link voltage regulation with balanced dual-output voltage making it highly suitable for mid-point converter fed SRM drive. The conventional diode bridge rectifier along with power factor correction converter uses a greater number of elements to achieve the similar performance. The overall grid-supported SRM driven solar water pump drive is modelled and simulated in Simulink environment and the performance of the drive is evaluated during different operating modes. It is observed that, under all operating conditions, the power quality indices of the utility mains are in compliance with the IEEE-519 standard.
