Vector Control of an Induction Motor in a Solar Water Pumping System

This paper analyzes the performance of a solar water pumping system based on an induction motor, utilizing vector control and solar energy optimization to enhance system efficiency. The proposed system comprises solar panels, boost converter, a three-phase inverter, and energy storage systems that ensure stable power during reduced solar radiation. The Incremental Conductance (INC) algorithm is used for the Maximum Power Point Tracking (MPPT) of the solar panels, and vector control is applied to regulate the motor's torque and speed. Simulation results demonstrate that the solar water pumping system can perform effectively under varying radiation conditions using vector control and a battery energy storage system to improve stability. Additionally, the impact of an LC filter on improving stator current quality and reducing Total Harmonic Distortion (THD) is investigated. The results indicate enhanced system efficiency and stability across diverse environmental conditions.
