Simulation of A Solar Powered Water Pumping System Using Induction Motor

Abstract: Sun is one of the most abundantly available sources of renewable energy, which is the major solution for future energy crisis. In this paper presents solar based water pumping system. The pump system uses two converters. One is a DC-DC boost converter and the other is a three-phase DC-AC inverter. Boost converter used to step up the voltage from PV panel also to obtain constant voltage to the inverter. VSI is used as the inverter and used to provide AC voltage to the motor section. Motor used here is a three-phase induction motor since it shows more advantages concerning of availability and cost. The installation cost of the PV is very high, so when it is installed the next step is to extract maximum power from the panel of installed capacity. Suitable MPPT method is also used. To control the speed of induction motor V/F control method is used. The detailed design and MATLAB /SIMULINK model of the system is given.
