A Comparison between Directly Connected and MPPT Connected Solar Powered Water Pumping System using PMDC Motor
Abstract
This paper represents a comparative analysis of two photovoltaic pumping systems. To study the performance of the MaximumPower Point Tracking (MPPT) system, two models were simulated using Matlab/Simulink and the performance of a directlyconnected photovoltaic (SPV) pumping system was compared to an MPPT connected SPV pumping system at various levelsof solar irradiance. The MPPT system maximizes overall system efficiency, but makes the system complex compared to thedirectly connected SPV pumping system. Instead of the conventional boost converter the MPPT system contains a buckconverter to maintain overall system voltage at the lower levels required by the permanent magnet DC (PMDC) motor. Forsimplicity, the MPPT controller follows the perturbation and observation (P & O) algorithm and controls the buck converterto maximize overall system efficiency at various levels of solar irradiance. The PMDC motor provides high weight-to-torquedensity, better speed control, low inertia, and lower losses compared to induction and the conventional DC motor. Thecomparative analysis shows that the MPPT connected SPV system is more efficient than the directly connected SPV systemfor water pumping purposes using a PMDC motor.References
