Design and Analysis of Solar PV Fed IMD Water - Pumping System

This paper presents a water-pumping system using solar photovoltaic Arrays. The system consists of PV array, DC-DC boost converter, voltage source inverter, 3$-\Phi$ induction motor drive (IMD) and centrifugal pump. The modified space vector pulse width modulation (MSVPWM) method for control of inrush current and drive's commutation uses lower number of sensors. The main advantages of MSVPWM are its high efficiency, low cost due to reduced number of sensors and low harmonic current. The developed system model is simulated in the MATLAB/ Simulink software and its results are discussed in this paper. The system provides satisfactory performance in the dynamic, steady state conditions.
