[IEEE 2019 7th International Renewable and Sustainable Energy Conference (IRSEC) - Agadir, Morocco (2019.11.27-2019.11.30)] 2019 7th International Renewable and Sustainable Energy Conference (IRSEC) - Design and Performance Analysis of a Photovoltaic Water Pumping System based on DC-DC Boost Converter and BLDC Motor
摘要： This paper presents the modeling, control and optimization of a photovoltaic water pumping system. The system consists of a DC-DC Boost converter, which is used as a link between a Solar Photovoltaic (SPV) panels and the three-phase inverter (VSI) to feed the BLDC motor. A centrifugal pump is connected to this motor in order to use the water pumped afterwards to multiple applications. Maximum Power Point Tracking (MPPT) control techniques are an essential part of improving the efficiency of photovoltaic (PV) systems. It is principally used to extract maximum possible power of the PV modules under any condition of solar irradiation. For this reason, P&O algorithm is used due to its high performance and its simplicity of implementation. The DC-DC Boost converter, compared to the various common DC-DC converters (Buck, Buck-Boost, SEPIC, Cuk...) has many benefits in SPV based applications, such as limiting the starting current of the motors. Using a BLDC motor is found to be the best option because of its high efficiency and reliability, better performance, and requires low maintenance. The considered system as well as the control strategies has been implemented in MATLAB-Simulink environment. The results show the effectiveness of the studied photovoltaic water pumping system.

[IEEE 2017 International Conference on Current Trends in Computer, Electrical, Electronics and Communication (CTCEEC) - Mysore (2017.9.8-2017.9.9)] 2017 International Conference on Current Trends in Computer, Electrical, Electronics and Communication (CTCEEC) - Development, Testing and Performance Analysis of SPV Powered 0.5HP AC Water Pumping System
摘要： This paper presents the implementation and testing of SPV powered 0.5HP AC water pumping system. DC pumps are widely used in SPV based systems. However, the cost employed for DC pumps is much larger in comparison to conventional AC pumps. In the proposed system inverter is designed for 400 W SPV panel connected to 0.5HP pump. The experimental setup is in Energy Park, Basaveshwar Engineering College built (Autonomous), Bagalkot, India. Further, performance analysis of the SPV water pump under varying conditions of solar radiation is carried out. Solar radiation, SPV output, Inverter output, Inverter efficiency, Flowrate from pump, Hydraulic power output and Pump efficiency are experimentally obtained and tabulated. Performance results revealed that, proposed model delivers 45-50 liters of water per minute from the depth of 3m water tank. Maximum efficiency of inverter and entire unit is obtained at highest solar radiation of 1195W/m2. The results indicate the efficient working of the implemented system for at least 4 hrs, between 11:00am to 3:00pm of a day. The proposed the cost and decreases dependency on conventional energy sources, while satisfying the water requirement in small scale agriculture and gardening.

AIP Conference Proceedings [AIP Publishing TECHNOLOGIES AND MATERIALS FOR RENEWABLE ENERGY, ENVIRONMENT AND SUSTAINABILITY: TMREES19Gr - Athens, Greece (4–6 September 2019)] TECHNOLOGIES AND MATERIALS FOR RENEWABLE ENERGY, ENVIRONMENT AND SUSTAINABILITY: TMREES19Gr - Comparative study on photovoltaic water pumping systems driven by direct current motor (DCM) and induction motor (IM) optimized with P&O control
摘要： This paper presents a comparison between two photovoltaic water pumping system driven by a separately excited DC motor (DCM) and an induction motor (IM), via a DC/DC buck-boost converter coupled to a centrifugal pump. The two systems are optimised by a P&O MPPT algorithm, which aims to the maximisation of the global efficiency, will lead consequently to maximize the drive speed and the water discharge rate of the coupled centrifugal pump. Each component of the PV water pumping system is studied and analyzed in MATLAB/SIMULINK. The two systems are then compared in terms of efficiency and quantity of water pumped per day. The study concludes that the IM-driven PV system yields highly favorable results and requires less maintenance compared with other systems.
