Experimental Evaluation of BLDC PV Agricultural Irrigation Pumping System in Desert Environment at Ghardaia, Algeria

This study presents the outdoor performance assessment of 1. S kW solar-photovoltaic water pumping installed in real well at Ghardaia, southern region of Algeria. A typical PV pumping system for irrigation is placed on a 25 m head water well employing the recent version of centrifugal Lorentz PS2-1800 C-SJ5-12 solar pump based on three phase brushless DC motor. The performances of three oversized PV array generators ($4s\times 3p$, $4s\times 4p$, $4s\times 5p$) are compared to obtain the suitable configuration. In other hand, to determine the lowest limit performance of the selected configuration, the system is examined in winter (cloudy and short days in unfavorable month) and in summer (warm and tilt angle). The experimental results demonstrate that an oversizing rate of 46% offer the better operating performances which can gives 47.49 m3/day and 34.42 m3/day in summer and winter respectively.
