摘要：This work presents a study and design of a large-scale solar energy powered groundwater pumping system for irrigation in Najaf city - Iraq. The system is expected to produce sufficient water pumping to cover the specified area. We built two system depended on daily water use for wheat to calculate number of pumps, panels and the power of each panel, the first case study for 28 m ground water depth which needs 16 pumps and each pump need 80W,10 panels and 300 w power for each panel. The other case study for 100 m ground water depth which needs 5 pumps and each pump need 500W, 20 panels and 250w power for each panel. The System is done by using Matlab/Simulink which contains solar arrays; stages DC-DC boost converter, DC shunt motor, and centrifugal pump. In addition, perturbation and observation (P&O) algorithm based maximum power point tracker (MPPT) was used to improve the system efficiency. The results show that the system able to coverage the specified area with sufficient water to irrigate the crops required. And in RETSCREEN after determined our location calculated the Daily water use per unit, Water use reduction, Electricity- daily, Electricity-annual and reduction and the emission of 5.9 tco2 that is equivalent to 13.8 Barrels of crude oil not consumed. The result show that the system able to coverage specific area with sufficient water to irrigate the crop required.
