Solar PV based permanent magnet synchronous motor drive for water pumping application

Abstract

In remote and hilly areas water pumping for domestic usage can induce heavy cost due to high cost of power transmission to those areas. The utilization of solar photo voltaic (SPV) energy is progressive at these areas. The conversion efficiency of SPV is increased efficiently by improving Maximum power-point tracking (MPPT) techniques which are easier, low cost and can be implemented on existing SPV systems. Moreover, using PMSM drive for water pumping will reduce the size requirement of SPV compared to Induction motors (IM) and brushed DC motors and also PMSM provides almost no maintenance. Keeping in view the present requirement, this project proposes an SPV powered PMSM water pumping drive with Perturb&Observe(P&O) and Incremental-Conductance (INC) MPPT techniques for optimizing the efficiency of SPV.
