Novel control of Multi Motor Driven Photovoltaic (PV) based Water Pumping System with HIL

Abstract

Photovoltaic (PV) based water pumping systems driven by induction motors are used for many applications recently. Using of batteries for power backup can increase the overall system cost as well as required daily maintenance. Hence, the designing of a water pumping system without using battery backup is very important aspect when power supplied by PV panels. N efficient energy management system is developed in this paper and compared the response with various conditions. Hardware-in the-Loop (HIL) based results are incorporated in results section along with Simulink results to validate the proposed configuration. Two different control schemes based on power and voltages are proposed in this paper with the help of vector control of induction motor. Moreover the control scheme is implemented to operate identical multi motors. The seamless control technique is implemented to switched ON second motor based on availability of power from PV system.
