Solar Powered Based Water Pumping System Using Perturb and Observation MPPT Technique

ABSTRACT:

This paper concentrates on solar photovoltaic(PV) water pumping system using perturb and observation maximum power point tracking(MPPT) technique. This whole system is divided into two stages. In the first stage, an arrangement of PV modules is made which is a combination of number PV cells in series or parallel to extract the solar energy and convert into electricity. To maximize the power output of PV module, perturb and observation (P&O) MPPT technique has been used. In its second stage, direct torque and flux control(DTFC) with space vector modulation(SVM) is used to control switching pulses of the voltage source inverter(VSI). The speed of induction motor drive is controlled by DTFC technique. The whole system is developed in MATLAB and outputs are observed.

CONCLUSION:

In this paper control methods which regulates the flow rate of water supply of solar powered based water pumping systen using IMD is illustrated. From the simulation results it can be concluded that this system has good performance. As per view of irrigation system , the SPV array has been operated under standard enviromental conditions. The system is operated on maximum power by using P&O MPPT algorithm. Water flow rate and stator current of motor is controlled by the speed PI controller.
