Mr Design and Analysis of Fully Solar driven Mini-Food Processing Unit

Abstract

This paper comes with an optimized design to drive the mechanical agricultural processing units associated with the existing underutilized solar photovoltaic (SPV) power, available at solar water pumping (SWP) system. This enables energy independent solar driven mini-processing units. The fabricated system is designed to operate at a low cost, as energy storage system is not being utilized, and it aims to retain the DC power supplied by SPV via DC-DC power conversion stage. The PV system is integrated with a power electronic interface to supply power BLDC motor drive coupled with wet grinder. The developed hardware was tested under different load conditions and data was analyzed through graphs. The experimentation is carried out in fabricated setup to validate the design and results indicates the operational efficacy. Additionally, the impact of weather intermittency is considered on proposed system to confirm its effectiveness. This proposed system is well suited for rural areas to reduce the grid dependency and boost rural economy utilizing the under tapped SPV power.
