This paper is dealing with the design and
simulation of single stage solar powered water pumping
system using 5 hp three phase induction motor coupled
to the pump. The main scope is for providing a economic
way for pumping water to sub-urban areas. In this paper
the designing and evaluation of the solar panels powered
induction motor driven water pumping system is
configured. The main functions of the proposed control
strategy are: 1) making sure that starting motor is
successful, 2) matching the available PV power with the
available induction-motor pumping load, and 3) making
the PV system for operating at the maximum power
point by using MPPT algorithm. The simulation outputs
will be available in numerical or graphical format. The
induction motor has been chosen because these type of
motors are low cost and are more robust when compared
to the conventional DC motors. It is being expected that,
with use of an induction motor, for equal amount
investment the system performance may improve
significantly. The energy source is a photovoltaic (PV)
module as it is a current source. The Modelling &
Simulation of system is being carried out with MATLAB
software. The PV panel structure is designed for
maintaining the systems operating point at the PV
operation of the unified system using and not using
controller in non varying and varying solar irradiations.
The important objective is to run the system in non
varying and varying solar irradiations as close as
possible at the maximum power point operation
