Solar water pumping

Abstract

In this work, three-phase double stage water-pumping photovoltaic system using current control inverter is simulated using Matlab/Simulink. To deal with varying irradiance conditions, the Perturb and Observe (P&O) MPPT has been used. The main part of the project that is the control of AC motor using hysteresis field oriented control method has been implemented. The proposed system consists of two-level inverter, the converter used is a Voltage Source Inverter (VSI) which is controlled using synchronous d-q reference frame to inject a controlled current into the AC induction motor .
