This work aims to design a standalone solar photovoltaic (SPV) system to operate variable frequency drive (VFD) for palm trees irrigation using bubblers and control the irrigation network. A complete irrigation system is designed and constructed in two fields of date palm trees. A small photovoltaic (PV) system is used to operate the rainbird controller which changed water delivery from one subline to another after a predetermined time. The performance of the developed system is evaluated under different operating factors and its costs are analyzed. Water distribution uniformity and soil moisture at different depths in the root zoon are measured. The frequency of supply voltage is influential in controlling the speed of the induction motor, whereby operating the inverter, the motor speed is constant without any oscillation. Irrigation through the last two laterals in field II indicated that the required maximum hydraulic energy and maximum PV array power was 7.81 kW h/d and 3.74 kWp, respectively at the total dynamic head of 22.75 m. The coefficient of variation of bubblers flow was a small value for a single lateral (3.83 %), while for two laterals it varied from 8 to 12 %. The total dynamic head reached about 22.75 m for the last sublines in field II. The average subsystem efficiency was about 0.41. The annual cost of unit power of PV system was 0.161 $US /kWh without subsidies. The proposed SPV pumping is cost-effective and controlled the motor efficiently without energy backup.

这项工作旨在设计一个独立的太阳能光伏 (SPV) 系统，以操作变频驱动 (VFD)，使用鼓泡器进行棕榈树灌溉并控制灌溉网络。在椰枣树的两个领域设计和建造了一个完整的灌溉系统。一个小型光伏 (PV) 系统用于操作雨鸟控制器，该控制器在预定时间后将供水从一条支线更改为另一条支线。在不同的操作因素下评估开发系统的性能并分析其成本。测量了根区不同深度的水分分布均匀性和土壤水分。电源电压的频率对控制感应电机的速度有影响，从而操作逆变器，电机速度恒定而没有任何振荡。通过田地 II 的最后两个支管灌溉表明，在 22.75 m 的总动态水头下，所需的最大水力能量和最大光伏阵列功率分别为 7.81 kW h/d 和 3.74 kWp。起泡器流量的变异系数对于单支管来说是一个很小的值 (3.83 %)，而对于两条支管，它的变化范围为 8 到 12 %。油田 II 中最后一条支线的总动态水头达到约 22.75 m。平均子系统效率约为 0.41。光伏系统年单位功率成本为0.161美元/千瓦时，无补贴。提议的 SPV 泵送具有成本效益，并且无需备用能源即可有效地控制电机。起泡器流量的变异系数对于单支管来说是一个很小的值 (3.83 %)，而对于两条支管，它的变化范围为 8 到 12 %。油田 II 中最后一条支线的总动态水头达到约 22.75 m。平均子系统效率约为 0.41。光伏系统年单位功率成本为0.161美元/千瓦时，无补贴。提议的 SPV 泵送具有成本效益，并且无需备用能源即可有效地控制电机。单支管的起泡器流量变异系数很小 (3.83%)，而两条支管的变化系数从 8% 到 12%。油田 II 中最后一条支线的总动态水头达到约 22.75 m。平均子系统效率约为 0.41。光伏系统年单位功率成本为0.161美元/千瓦时，无补贴。提议的 SPV 泵送具有成本效益，并且无需备用能源即可有效地控制电机。
