Single Stage Solar PV Inverter Equipped to Water Pumping System

Abstract

One of the greatest issues facing Egypt's agriculture sector is proper irrigation management. The Egyptian government is currently working to extent the area of cultivated land, especially in remote and rural areas. Since these areas are not connected to the national electric grid, it was necessary to migrate to the new and renewable energy alternatives. Due to Egypt's geographical location, solar energy is one of the most viable choices to these new technologies. Solar inverter is considered as one of the most important components of solar energy systems especially those operating irrigation pumps. This study details the design and development of a single stage solar photovoltaic (PV) inverter that powers a water pump for irrigation. The pump is driven by a three phase AC induction motor powered by the inverter output. A new control approach could be used to control the suggested three phase boost type inverter. The suggested inverter can inject sinusoidal currents into induction motors that drive pumps. The proposed topological design, as well as the analysis and operation concept, are addressed. To demonstrate the suggested inverter's effectiveness, simulation results are run in Matlab/Simulink software. Finally, Computer simulations and experimental verification have shown encouraging results and it is felt that the proposed topology has good potential for applications in water pumping systems.
