Intelligent Solar Water Pumping Scheme with BLDC

Abstract

Along with increased pumping system reliability, this also allows for the full usage of a PV array and motor-pump. A single-phase voltage source converter (VSC) uses a unit vector template (UVT) generation technique to achieve bidirectional power flow control between the grid and the voltage source's DC bus. A BLDC motor is fed by an inverter (VSI). Furthermore, a PI controller cannot achieve enhanced PQ features by regulating the DC capacitor voltage in the UVT controller to a desired level. However, the tuning concerns of the existing controller lead to its unpopularity; a revolutionary intelligent fuzzy-logic controller can resolve these issues and achieve good performance features. The suggested intelligent fuzzy control systems, which outperform the traditional PI controller, find widespread employment in various applications. In order to improve PQ, this study evaluates the efficiency of solar-PV and grid-integrated water pumping systems using traditional PI and intelligent fuzzy-logic controllers. Results are presented on how the Matlab/Simulink platform is used in this system to achieve the maximum power point (MPP) functioning of a PV array and power quality enhancements such power factor adjustment and reduction of the total harmonic distortion (THD) of the grid.
