Simulation and experimental validation of AC motor and PMDC motor pumping system fed by photovoltaic cell

Abstract

<span style="font-size:9.0pt;mso-bidi-font-size:12.0pt" lang="EN-US">Solar water pumping is a promising renewable alternative to conventional water pumping for large, medium and small power applications. This system is also useful in remote areas where electricity is not available and it is very expensive to lay long transmission lines. This paper deals with basics of solar powered water pumping system and the comparison of performance between AC motor and PMDC motor pumping systems. In this work, the MATLAB based modelling of a PV array, single-phase induction motor and permanent magnet DC motor are studied and developed.<b> </b>The photovoltaic is used to feed power to the water pumping systems. <span style="mso-bidi-font-weight:bold">The performance characteristics of single-phase induction motor and permanent magnet direct current motor are obtained by using MATLAB simulation and are validated with experimental results. From the experimental results, it is found that the<b> </b>permanent magnet direct current motor is best suitable for photovoltaic water pumping than the single-phase induction motor in low power applications.
