PMSM-Driven Solar Water Pumping System

Abstract

In this paper the study describes a single-stage, self-contained solar photovoltaic (SPV) array-fed, permanent magnet synchronous motor water pumping system (PMSM). The two main contributions of this research are i) the development of a novel modified vector control (MVC) that improves the system's torque behaviour and (ii) the development of a special incremental conductance with variable step size (VSS-INC) with a stage technique that results in a rapid response. Maximum Power Point Tracking (MPPT) is offered, a DC-DC converter between stages is not required, and (iii) the system's overall response time under dynamic conditions is enhanced with the use of an SPV Power Feed Forward Term (FFT). A pump, a three-phase voltage source inverter (VSI), a PMSM, and an SPV array are among the parts of this system. Solar energy is transformed into electrical energy by the SPV array. The VSI performs the role of a power processing unit (PPU), supplying the necessary power to drive the PMSM. The motor-coupled pump completes the task of pumping water while the PMSM rotates. The provided empower system toolbox is used with MATLAB/Simulink to model and simulate this system.
