Design and Analysis of a Water Pumping System with Photovoltaic Source and Switched Reluctance Motor

Solar energy is a clean energy and it is increasingly being used all over the world. In this study, a centrifugal water pump system driven by switched reluctance motor (SRM) has been designed with powered by a photovoltaic (PV) energy source. The voltage of the PV source has been increased by using a boost converter. The mathematical model of the system has been composed in the Matlab/Simulink and simulation results have been obtained. Proportional–integral–derivative (PID) controller has been used to control output voltage of the boost converter at 50 kHz switching frequency. The boost converter is controlled by an eight-bit PIC16F877A microcontroller. The electrical energy obtained by PV panels has been stored in batteries. Battery charge testers have been used to control the battery charge level. The speed and current control of SRM has been done by using DS1103 Ace kit. The values of phases currents have been measured by using hall sensors and transferred to the digital signal processor (DSP) by analog to digital converter inputs. The accuracy of simulation results has been proved by experimental results.
