Abstract:
This paper deals with a stand-alone, improved, reliable and efficacious water pumping system utilizing a brushless direct current motor (BLDC) drive. The developed topology of BLDC pump drive is energized by solar photovoltaic (SPV) array and supported by the battery energy storage system (BESS) which facilitate SPV-BESS hybrid system competent enough to pump required volume of water uninterruptedly the whole day regardless of variations in atmospheric condition. A 2-stage interleaved boost converter (IBC) is employed in conjunction with drift free P&O MPPT algorithm to extract maximum accessible power from the PV array. A 3-ph voltage source inverter (VSI) is utilized to control the BLDC motor complying a fundamental frequency switching. A bidirectional DC-DC converter (BDC) is intended to regulate DC link voltage at a desired value to control the power flow by charging/discharging operation of the BESS to maintain the rated speed operation of the motor. The continuous conduction mode (CCM) operation of 2-stage interleaved converter reduces the ripple current, I2R losses, increases the effective switching frequency and fasten the transient response of the system. The proposed system is modelled in MATLAB/Simulink and is examined under dynamic operating conditions. The obtained results validate its efficacy and effectiveness of the developed BESS assisted stand-alone water pumping system.
