International Journal of Power Electronics (IJPELEC), Vol. 7, No. 1/2, 2015

Abstract: This paper deals with a solar photo voltaic (PV) array fed water pumping system. This system includes solar PV array, a boost converter controlled by using perturb and observe (P and O) control algorithm for extracting the maximum power from solar array and the vector control for the controlling speed of an induction motor drive used for driving the water pump. The reference speed is estimated from the affinity law and dc-link voltage proportional-integral (PI) controller. The developed model of the system in Matlab/Simulink has been used to simulate its performance. Simulated results have demonstrated the satisfactory performance of the controllers both in steady state and dynamic conditions.
