Performance Analysis of Solar based Induction Motor for Water Pumping System

Performance analysis of solar photovoltaic array fed single phase induction motor (IM) drive for water pumping system. In the proposed method, the output DC power of the solar PV array is stored in battery and the stored DC energy is directly fed as input to the inverter and output of the inverter is fed to the single phase induction motor for water pumping system. A centrifugal pump connected with the single phase indication motor for water pumping system. The size of PV array and motor rating selected such that the water can also be pumped during the varying in temperature and irradiation level. This study evaluates the performance parameters namely current, speed, temperature and vibrations. The GUI is developed to control the action of motor and monitor the above mentioned parameters values through appropriate sensors and microcontroller. The speed control through microcontroller by varying the pulse ON duration is studied a well as the effect of speed on vibrations is also observed. The critical experimentation is carried out to analyze the above said parameters and examines the effectiveness the single phase induction motor for solar PV based water pumping system.
