Performance Evaluation of Doubly Fed Induction Motor for Smart Irrigation Systems

This article investigates the performance of the doubly fed induction motor (DFIM) in smart irrigation systems, where the motor's ability to control water flow by adjusting its speed is explored. The study demonstrates that DFIM can be treated as a variable-speed synchronous motor with similar torque-speed characteristics. A mathematical model is developed to optimize its performance in smart irrigation systems, considering specific application conditions. The experimental setup results show a good correlation with the theoretical findings, indicating the potential of using DFIM in smart irrigation systems to enhance their efficiency and control while lowering costs. The results also investigate the influence of stator and rotor voltage and current variations on the motor's characteristics and power factor, highlighting the DFIM's ability to change its power factor by adjusting the rotor current and thus improve its performance as a synchronous motor.
