研究目的
Investigating the performance of a hybrid photovoltaic (PV)-thermoelectric generator (TEG) system for pumping applications, focusing on improving system performance and reducing cost and complexity by eliminating the need for DC-DC converters and batteries.
研究成果
The hybrid PV-TEG system significantly improves the motor output power and pump flow rate compared to using only a PV array, without the need for DC-DC converters or batteries. This results in improved system performance and reduced cost and complexity. Experimental measurements validate the simulation results, demonstrating the potential of this system for pumping applications in remote areas.
研究不足
The study assumes uniform irradiation level distribution over the PV modules and a constant ambient temperature, which may not always be the case in real-world applications. The performance of the TEG array is not maximized at all irradiation levels, indicating a potential area for optimization.
1:Experimental Design and Method Selection:
The study employs a hybrid PV-TEG system connected to a synchronous reluctance motor (SynRM) for pumping applications. A control strategy is designed to maximize the output power of the PV system and achieve maximum torque per Ampère condition in the motor.
2:Sample Selection and Data Sources:
The system uses PV and TEG modules with specified models to simulate and validate the theoretical model under different weather conditions.
3:List of Experimental Equipment and Materials:
Includes PV modules (KD135SX-UPU), TEG modules (TE-MOD-1W2V-40S), a three-phase voltage source inverter, a synchronous reluctance motor, and a centrifugal pump.
4:Experimental Procedures and Operational Workflow:
The system is simulated in MATLAB environment, and an experimental test bench is constructed to validate the simulation results. The test bench includes a SynRM, an induction motor, power analyzers, sensors, a dSpace controller board, and a controlled DC supply.
5:Data Analysis Methods:
The performance of the system is analyzed based on motor output power, pump flow rate, and efficiency under different irradiation levels.
