Design and Analysis of PV Powered Water Pumping System using Permanent Magnet Synchronous Motor

Solar powered water pumping is one of the major applications of solar energy in remote areas. Mostly in developing countries the rural areas are not often connected with main grid hence people have to depend on standalone system for various energy needs. In remote areas supply of electricity from national grid has remained largely uncertain and out of reach as well as the price of diesel makes cultivation costly. Moreover during summer months the erratic and non-availability of power supply creates hindrance in the daily activities of rural people For water pumping purposes traditionally DC motors were used but due to easy availability of AC motors with highly efficient features and rigid construction the trend has shifted from DC motor to AC motor. Moreover among AC motors permanent magnet synchronous motor is highly efficient and available in more compact size as it includes features of both DC motor and induction otor. Use of battery also increases maintenance cost. In this paper Photovoltaic water pumping system is designed using ac motor i.e. permanent magnet synchronous motor and without battery. MATLAB/Simulink is used to carry out the research work.
